grejen Posted February 18, 2014 Share Posted February 18, 2014 Along with recently earning my Canadian Rec Pilot Permit I've also been learning how to create Android apps. Since my high school math skills were 30+ years old I built an app to practice doing the diversion / ground speed check math. Here is the trial version of Diversion math practice 1 Link to comment Share on other sites More sharing options...
Gnarly Gnu Posted February 19, 2014 Share Posted February 19, 2014 Great! I just bought this book "M3: the mile, the mach, the minute" mental math for Aviators, similar theme. Link to comment Share on other sites More sharing options...
grejen Posted February 20, 2014 Author Share Posted February 20, 2014 Very similar. I'm hoping to build more of these types of apps. Just released this one today for learning/practicing the ICAO phonetic alphabet https://play.google.com/store/apps/details?id=appinventor.ai_grejen711.ICAOPhonetic Link to comment Share on other sites More sharing options...
Oksinay Posted February 20, 2014 Share Posted February 20, 2014 Hi guys Could you make an app to practice CTA readbacks? I have a PPL with CTA/CTZ endorsement, but rarely use it and it is definitely an acquired skill. 1 1 Link to comment Share on other sites More sharing options...
grejen Posted February 21, 2014 Author Share Posted February 21, 2014 Great idea! Interesting problem too. It'd have to read out random but sensical instructions and check the read back with some ability to 'judge' for missing/erroneous content. Saying "...one six right..." instead of "...one six left..." would be a definite fail but skipping the word 'cleared' might be less so. It'd have to have some AI built in...

Oksinay Posted February 21, 2014 Share Posted February 21, 2014 Perhaps it could just record and playback so that the trainee could self assess? Link to comment Share on other sites More sharing options...
grejen Posted February 21, 2014 Author Share Posted February 21, 2014 Btw - what does CTA / CTZ stand for. I'm guessing (and googling) that it's similar to the ATC (Air Traffic Control) or Control Zone airspace (Bravo/Charlie) here in North America.

grejen Posted February 21, 2014 Author Share Posted February 21, 2014 Perhaps it could just record and playback so that the trainee could self assess? Like this: http://www.aviatorwebsite.com/education/communications/phonetic-practice.php ah.. no you mean record a practice readback so you can listen to yourself. hmmm....doable for sure. Ideally an app - like my phonetic alphabet app - could listen to your readback do the voice recognition and pick out the keywords to compare to an expected response, and then provide usable feedback (ie a 'score') about the performance. I know the flight sims are starting to include real time live ATC, traffic, and weather but I doubt any of them can listen to a pilots radio calls and make any 'sense' of them.

grejen Posted February 21, 2014 Author Share Posted February 21, 2014 Very nice blog / podcast site from an ATP. http://atccommunication.com Seems he's working on an aircraft radio simulator. Link to comment Share on other sites More sharing options...

grejen Posted July 4, 2014 Author Share Posted July 4, 2014 Published another app (free/no ads.) This one is a reenvision of the 'Whiz wheel' wind vector calculator. My hope is that it's actually quicker and easier to use and learn. Plus it includes a practice game page where you can practice estimating the WCA in your head. There are a couple of methods for doing this: http://www.luizmonteiro.com/Article_Estimating_Wind_Correction_Angle_01.aspx and https://groups.google.com/forum/#!msg/rec.aviation.student/BLgeSZRy_Mk/78cS4W_ADFEJ After reading those methods I created the game page to practice the mental arithmetic. My concept is that the best and most credible backup for any device be it a tablet, E6B, calculator, GPS or even a full glass cockpit, is the pilot's own head. My hope is to build this app into a tool to actually teach the methods above rather than just provide a way to practice them. 1 Link to comment Share on other sites More sharing options...
metalman Posted July 5, 2014 Share Posted July 5, 2014 I read the heading and was going to post something smart ar*s, but after reading the post you've got some good ideas , until we moved to Melbourne I rarely went into controlled airspace so I was really out of my comfort zone when I started doing it more often , the read back checker would be a great one if you could get it doing the word recognition , the phraseology is standard here so if you get it wrong you have to read back tiill it's right , good luck with it Matty Link to comment Share on other sites More sharing options...
grejen Posted July 6, 2014 Author Share Posted July 6, 2014 I've been keeping that one in the back of my head for a while. Would be a great app if it works really well. I have two thoughts on how to generate the instructions: 1. Use real, recorded ATC instructions which have been transcribed. 2. Randomize standard phraseology and use text-to-speech The main disadvantage of the 1st option is you need to transcribe the instructions and check the transcriptions. This is a huge ongoing resource problem. The main disadvantage of the 2nd option is that it's...well.. not realistic. Text-to-speech is typically way clearer than a real radio transmission. If there is value in simple repetitive readbacks then option 2 is the way to go. If the value rests with the ability to understand real ATC over real radio then option 1 is necessary. Thoughs?
