Learn to Fly in Canada

I think a lot of kids wish that they could be a pilot when they grow up.  Unfortunately, many never decide to follow that dream.  I myself wasn't the same.  I can't really remember any specific career that I wanted to have as an adult, but I'm pretty certain that being a pilot definitely wasn't even on my radar.  It wasn't that I wasn't familiar with aviation ... I read tons of books about aviation, planes, rocketry, aviation, and that sort of thing while growing up.  But it was only about a year and a half ago that I decided that I wanted to learn how to fly.

People who think about getting a pilot's license are often deterred because of the challenges.  There are a definite a couple obstacles.  First, the cost is not insignificant.  It's possible to get a basic regular PPL (private pilot's license) in Canada for perhaps as little as $15,000.  But I'd recommend that students budget closer to $20,000, unless you've done a lot of studying in advance, and you're able to do it in a fairly short calendar time frame (a few months).  Otherwise, you'll end up wanting to do refresher flights quite often, because you'll forget things if you're not practicing regularly.

 



Another challenge is that the material is not easy.  Most of the material covered in a Canadian private pilot license is not terribly difficult, but there is a lot of memorization, and parts of the flight theory, navigation, and meteorology sections can be tricky.

In addition, depending on where you live in Canada, it can be difficult to find instructors.  Weather is also an issue - although a plane flies much more easily in cold weather in winter, many students try to avoid lessons when it's cold out.  And finally, if you're a bit nervous of planes or heights, or get nauseated easily, your first couple of flights might be tricky (don't worry, all of those minor problems start to disappear quickly after half a dozen lessons!).

I can't help anyone with money, finding an instructor, or a fear of heights.  However, I can help with the theory and memorization part!  As I was working on my PPL license, I made pretty extensive notes to help myself study, and I'm posting them here so they're free for anyone to use.  Please be aware that these notes are not a suitable replacement for the training that your instructor will do with you, nor as a replacement for going through ground school!  This is just some of the important information, laid out in a format that I hope will make it easier for you to study.

My notes were broken into seven sections.  I have both PDF versions of the notes, and audio (mp3) recordings, in case you want to listen rather than read.  The fastest way to download any of the items is through my public Dropbox account.  Go to this link:

www.djbolivia.ca/dropbox


Then look in the "Canadian Aviation" folder.  You'll see different sub-folders full of things, including my PDF study notes, my audio versions of my study notes, a folder full of posters and charts, and another folder full of public domain reference guides and materials.

I also have the study note PDF's available if you click on these links:



When you first go visit a flight school, you'll go on what's called a Discovery Flight.  This is a quick flight of about an hour, to let you get a sense of what it's like to be up in a small plane.  You may feel a bit nervous, but don't worry!  Your instructor may actually let you take the controls and fly the plane a little bit while you're up there on your first flight.  All training aircraft have two sets of controls, so don't worry, because the instructor will be able to override you if you do anything wrong.

For those of you who are nervous about being up there in a small plane, you've probably heard lots of statistics about how much safer airplanes are than cars.  It's true.  But here's one other thing that helps put safety into perspective.  You're used to driving a vehicle on the road, I assume?  Well, if you make a bad mistake with a vehicle, you could end up in the ditch, crashing, in about three to four seconds.  However, with a plane, it would probably take a couple minutes for you to get down to the ground.  This was one of the most memorable lessons that I learned quickly.  Even if you make a mistake and the plane starts to "fall out of the sky," you have TONS of time to think things through and react appropriately.  The only time you need to react fairly quickly is if you're diving at the ground, and that's simple enough to fix by slowly pulling up so you're in level flight again.  Incidentally, most people do their PPL training in Cessna airplanes, which are incredibly forgiving.  When you make a mistake, they're designed to usually return to a safer configuration on their own, without you touching the controls.

Anyway, some people approach their lessons differently than other.  Remember that there's the hands-on physical training, in the aircraft, but there's also a lot of theory involved (this part is called Ground School).  And there are a couple other side requirements (passing a basic "PSTAR" multiple choice exam, getting your medical done, and getting your radio license).  If I was going to recommend an order to approach everything, here's one possible way of doing it:

1.  Do your Discovery Flight, just so you feel what it's like to be in the plane in the sky.

2.  Spend a couple days reading and learning my "Beginner's Aviation" study notes.  You don't have to memorize it all, but this will give you a good base so you'll understand a lot more things when your instructor starts doing your flight lessons.

3.  Start with your regular lessons.  I'd try to go through at least two or three.

4.  Get your medical done.  Your instructor will tell you the requirements.

5.  Ask your instructor to get you set up for the P-STAR exam and the Radio License exam.  Once you have the study materials for those two exams, set of goal of something like two weeks to memorize it all and take your exam.  But keep flying while you're doing this!

6.  Once you have your P-STAR and Radio License, you need to really start learning the ground school material.  I'd recommend doing all the Air Law & Miscellaneous, and the Flight Theory & Aircraft sections first.  As you're still going through basic lessons, before you're allowed to try a solo flight, it's those two sets of study notes that will be most applicable to the hands-on learning that you're doing.  I should make a note here that if you're doing regular ground school in a classroom, you won't have much choice about timing of lessons.  If you're doing it through an online school, with videos and online testing, you proceed at your own pace.  I wouldn't recommend one approach over the other.

7.  Eventually, you'll be allowed to do your first solo.  This is a pretty significant milestone.  But before you do that, spend a day or two studying my Pre Solo Flight Basics study notes, and make sure that everything makes sense.  If it doesn't, review the appropriate manoeuvres with your instructor before you do a solo, even though your first solo will probably just be a couple of simple circuits around the airport.

8.  You still have a bunch of flight lessons to go through, but at this point, I would really take a couple weeks to go hard at learning the Navigation and Weather/Meteorology study notes.  But don't do this at the expense of continuing to fly.  You'll get rusty if you don't practice, so if it takes you more than two weeks to learn all of the Navigation and Weather/Meteorology, make sure that you keep doing at least one flight per week, to maintain your comfort level.

9.  Once you've learned Navigation & Weather/Meteorology, you need to go through the rest of your flight lessons.  While you're doing this, refer occasionally to the Abbreviations & Acronyms study notes.  That one is pretty much pure memorization, and I find that it's nice to review one or two pages each night.

10.  Now comes the big decision.  You're getting close to being ready for both your written final exam and your flight exam.  Which one do you do first?  Do you try to do them simultaneously?  Well, I wouldn't do them simultaneously.  There's a lot of last minute review that you'll probably want to do for each.  When you do the written exam, it takes a few weeks for you to get your mark back, so you might want to do that first.  With your flight exam, if you pass, you're basically going to know immediately.  But it can be tormenting if you pass the flight exam, but still need to go on to do the written exam, because that means that you can't fly your friends around for several more weeks!


Going into the flight exam, your instructor will basically take you up on mock flight tests, and make sure you're really at the point of being able to pass, before he gives you a recommendation to book an examiner.

For the written final exam, there's a really great study guide that you should pick up.  This is what it looks like:



You can find it by going to the www.VipPilot.com website, and searching for "Private Pilot Exam Prep Guide."  Worth every penny.

Incidentally, there's one more book that I haven't mentioned yet, which is pretty much "The Bible" for people who are learning to fly.  It's called, "From The Ground Up," by Sandy AF MacDonald.  A classic.  It's available from Amazon, and it also has a companion Workbook that you can buy.  I'm not sure what to recommend insofar as the "best point" in the learning process to read this book.  I didn't even start to read it until I was done ground school, and long after my first solo flight.  But it could be equally productive to read this entire book as the very first thing you do, even before your discovery flight.  It's gold Jerry, gold.




Here are links to a few websites that you might find to be useful:

Oh, and if it's more convenient, I also posted the audio versions of my study notes on Soundcloud, and you can download them individually that way too.  I'll keep updating these same widgets any time that I revise any of the material in the notes.

















Finally, learning about various types of clouds is a challenge for some students.  If you want to know about the definitive source for information on clouds, it's the World Meteorological Organization's "International Cloud Atlas."  Here's a link:




That's all for now.  Maybe some day I'll open a flight training school (although I still have a long way to go before that could ever happen).  In the meantime, enjoy learning to fly!  But be careful, it's pretty addictive ...

Learn to Use the Effects on a Pioneer DJM-600 Mixer

I just put together a video to try to teach you how to use the different effects on a Pioneer DJM-600 mixer. Although this mixer isn't really an industry standard anymore, it was for quite a few years. It will also be a good video for people with subsequent models to this mixer (such as the DJM-700, 800, 900, 1000, or 2000) because it will give you a basic understanding of how the effects on those other mixers originated. And actually, some of the effects on later mixers are the same.

Eventually, I'll put together some short update videos for some of those other mixers to give you information about effects that they have which aren't found on the DJM-600.





This is part of the "Learn to DJ" series that I'm working on. Check out my Videos page on my main website to find detailed videos about a variety of music-related topics, from audio recording, to DJ'ing, to audio software, to music production, to music videos. Here's the link:

Plosives - A Background for Singers & Audio Engineers

Plosives are something that singers and audio engineers need to be concerned with. Well, especially audio engineers, although singers should understand the subject.

Basically, a plosive is like an explosion of air hitting a microphone during a recording process. Sing something like, "I'm on a Boat," with your hand about an inch in front of your mouth. Do you feel a sudden burst of air at some point? Try singing, "I'm on a plane." And then trying singing, "I'm in a car." Obviously, different sounds cause different amounts of that burst of air.

The worst sounds, ie. the ones that create the most significant plosives, are words that start with B's and P's. These are created by the lips. Nearly as bad are K and G sounds created by the body of the tongue. Also problematic are T's and D's, which are created by the tip (blade) of the tongue. And incidentally, some of those letters can be pronounced in different ways. For example, in English, the words "truck" and "the" both start with a T, but the T in "truck" causes more of a problem. I'm not entirely sure what the correct terminology for these different pronunciations is, but I personally call the sounds a "hard T" (in "truck") and a "soft T" (in "the"). I'm pretty sure those aren't the audiologically correct terms, but hopefully most people will understand what I mean.

All of the sounds that I mentioned above are caused by what are called the "stop consonants". That's because in order to make them, the flow of air through the mouth is temporarily stopped completely. In phonetic terms, this is also known as an "oral occlusive," a consonant in which the vocal tract is blocked so that all airflow ceases.

Are there other types of consonants besides stop consonants? Of course. "Fricatives" are partial occlusives which impede airflow in the vocal tract, but don't stop it entirely. And "nasals" are when the vocal tract is blocked, but air flows out the nose instead. Examples of nasals would be "m" or "n" sounds. Want to test those? Try placing your finger just under your nose and then say a phrase like "the bird flew over the lake." All of the sounds in that sentence can be produced in the mouth and vocal chords, and you don't need your nose. But if you try saying words like "motorway" or "nunnery" you're likely to feel some air coming out of your nose. It's faint, but it's there. Anyway, fricatives and nasals are not relevant to our intended topic for the day, so let's get back to plosives.

So why are plosives important? Well, as a singer gets closer to a microphone, the burst of air that comes out of the mouth will hit the microphone. Today's microphones are pretty sensitive. That burst of air hitting the microphone sounds different than the sound that should be hitting the microphone, namely the vibrating molecules that make a noise sound like it should. So instead of recording the proper sound, the microphone is partially recording the noise of air hitting the microphone, or essentially, a little wind-storm.

A secondary problem related to plosives is the fact that the closer a singer gets to a microphone, the better their voice sounds, in general. But as the singer gets closer, the plosives become more noticeable. A typical catch-22 situation.


So what is the solution? Well, I recommend that you try using a pop filter. Actually, every audio engineer will recommend that a pop filter the best solution for almost every vocal recording situation. But what is a pop filter? Well, it's a thin fabric similar to pantyhose, stretched over a frame. The pop filter is placed between the singer's mouth and the microphone, and it blocks the bursts of air from hitting the microphone, but the fabric is still thin enough that almost all of the sound of the vocalist come through (and you can boost the recording levels by a tiny amount to compensate, if necessary).

Here's a short thirty-second YouTube video to show you a pop filter:




Here are a couple of graphics that show what kind of difference you might see between a recording of a word without a pop filter (the first graphic), versus one with a pop filter (the bottom graphic). You can probably tell just from the visuals that the initial impact of the sound in the first recording is more harsh:






Now that you understand what plosives are, and how to reduce their impact with the use of a pop filter, it's time for further research. Tom Johnson writes a blog at I'd Rather Be Writing. He's got a post on it about plosives which is excellent because it has some accompanying sound files that help demonstrate what they can sound like. I'd recommend you check out his post, at this link:

Learn to DJ using Pitch-Controlled CD Players

I get lots of emails from all over the world, from people asking me advice about learning to DJ. I've taught quite a few people the basics of DJ'ing during one-on-one sessions, but that kind of teaching is not feasible for a global audience. So I've always been interested in putting together some good quality videos that I could share on YouTube, to help people out.

Although I've put a few videos online in the last year or two, this is the first time that I've done any about using CD players for mixing music. I've just put two videos online, which will be of interest to a lot of potential DJ's out there, or even to experienced DJ's who are curious to learn additional mixing techniques. Here's a photo of part of the setup that I used for this project (click on it to see it in more detail):



Basically, what I've done here is that I've recorded an hour-long tech-house set. Since I have a weekly EDM radio show, called Subterranean Homesick Grooves, I decided to use the 150th episode of the show as the centerpiece for these two tutorial videos. I recorded the show on a laptop while DJ'ing on a pair of Pioneer CDJ-2000 pitch-controlled CD players (attached to a DJM-600 mixer), and at the same time, I also recorded the DJ's "cue" audio feed. I filmed all of this with three high-definition video cameras.

Once I had all of those files dumped into my video editor, I turned them into a pair of videos. The audio track for one of the videos is the "master" output that the dance floor would have heard (which I used as episode 150 for the radio show). The audio track for the other video has the master output in the right channel, and the DJ's cue audio in the left channel, so the viewer will hear things exactly the same way that a DJ hears when performing. And although I used three camera views, the predominant view is straight down on the CD players and mixer, so the viewer can see exactly how I'm manipulating the effects and controls on all of the equipment. The "DJ's Cue Perspective" version of the video also starts off with about twenty-two minutes of technical explanations, to further explain the equipment and technical aspects. And of course, both videos are high-def, so you can full-screen them and see the equipment in pretty good detail.



Here's a link to the show on SoundCloud, which you can download if you want:






Here's the video which presents the making of SHG 150 from the DJ's perspective:





And here's the video which presents the making of the show from the dance floor's audio perspective (the master output signal on the mixer):




As I mentioned at the end of these videos, if you find these to be useful and you'd like to see more like this, follow me on Twitter and send me a tweet to let me know what you think of the videos. If I see some serious interest there, I'll make the time to produce some more videos like this. I'm also currently working on a couple of other DJ'ing videos which cover techniques for beat-mixing, the use of various mixer effects, and several other DJ-related topics. They should be online in a couple weeks.


By the way, here's a link to the blog posting about episode 150, which has the track listings for this mix:

http://djbolivia.blogspot.ca/2013/01/shg-radio-show-episode-150.html


And I just started to create a video index page on my main website, so it's easier to find tutorials that I've put online:

Audio Recording Tutorial #01 - Basic Recording with a HD Camera and a Wave Recorder

I’ve generally been using my DJ Bolivia YouTube channel for educational purposes.   My goal has always been to feature videos teaching about a number of music-related topics:  DJ’ing, using audio editors such as Ableton and Cubase and ProTools and other DAW’s, production of dance music from scratch, and the occasional music video.  But one additional group of videos that I’ve wanted to put together has been a series on basic audio recording techniques.

I just put together the first video in that series.  This one deals with very simple audio recording using the microphone on a HD video camera, and using a portable audio recording device.  It talks about some of the basic types of processing that a studio engineer would put on an audio track (particularly on vocals), which includes reverb, delay, chorus, and EQ’ing, although it only goes into any detail on the last of those four topics.  I predominantly use Audacity to illustrate some basic concepts, with just a bit of use of  Audition and VLC to help out with some other tasks.  Essentially, I’ve recorded a song (acoustic guitar and singing) and then extracted the audio from the recording devices, then I did some very simple processing in order to come up with a better quality audio file.

Here’s the video:



The video touches on quite a few different topics that a musician should become familiar with if you want to do any recording.  Here is a list of some suggested additional reference sites that you might want to check out, in order to learn more about topics that I mentioned:

Software Used:


Recording Devices:


Extracting Audio from Video using VLC:


Audio Frequency Spectrum:


Plosives:

Glen Ballard Scholarship at Berklee

I’m currently in the middle of working through two separate Masters’ programs through the Berklee College of Music, one in Music Theory and one in Production. I just found out that I am the recipient of a "celebrity scholarship," thanks to support donated by Glen Ballard.

For those of you who aren’t familiar with the name Glen Ballard, you should be. He is an R&B, rock, and pop songwriter and record producer who has had a hand in releases by an incredible number of artists. I’m going to list just a few of the artists that he has either performed with or done production work for, and you’ll see what a huge impact he has had on contemporary popular music: Michael Jackson, the Pointer Sisters, Wilson Phillips, Paula Abdul, Evelyn King, Van Halen, Aerosmith, Alanis Morissette, No Doubt, Shakira, Dave Matthews Band, Christina Aquilera, the Goo Goo Dolls, Annie Lennox, and dozens of others. Wow.


 





It’s quite an honor to be recognized for this scholarship. Now the only problem is that my cumulative GPA is only 3.82. I’m happy with that, but it could be higher. But now that I’ve finally returned home and to my personal studio today, after four months on the road, I’m excited to really dig into the course work more heavily and see if I can get that GPA closer to 4.0.

Many, many thanks to Glen, both for his support with this scholarship, and also for his diverse contributions to contemporary mainstream music.
