Good learning tool.


Great for answering the question “where are you in relation to the VOR or ILS? Especially good for those tricky reverse sensing problems when on an ILS. Back Course.

Excellent product

I use this extensively to test VOR knowledge. It is perfect.

Unrealistic instrument behavior

rvleic on

The CDI needle has very low resolution. It ticks in 1 degree increments. One dot is 2 degrees, so from full deflection to intercept is only 10 ticks... it looks terrible. The CDI does not move fluidly in an analogue manner like in real-life. There is not as much trend information as in real-life. Not good. Update: Your response is nonsense. I’ve used plenty of modern digital displays like Garmin G5 and G1000 and while the OBS is only capable of selecting a course in 1 degree increments, the CDI needle itself still moves fluidly in an analogue manner as bearing to the station is changed. Stop making excuses. The instrument in this app does not behave the same as a real life VOR indicator in virtually any GA airplane.



Don’t get me wrong— there’s nothing wrong with the app. But the price point is off base. This is a $1.99 app at most.

It doesn’t work at ios11. Please fix it.

CFI-I Review (Updated)

yinYangMountain on

Nav Trainer 3.4.1 IPad Pro 9.7 v.11.1.2 • Settings > Instruments “BIG \/ SMALL” does not work. • Motion sensors still changes heading at warp speed. Absolutely useless. • If you are going to provide an option for turning via the motions sensors, use an algorithm which works similar to a real control wheel/yoke. [Ref. X-Plane 10 for iPad] • Add delay variable when rolling in/out of standard rate. [Ref. VOR Tracker] • Based upon most textbooks (FAA, Jeppesen, ASA, Rod Machado, etc.) and typical training aircraft with ‘standard’ instrument configurations, the HI should be either on top or bottom—not in the middle of the NAV instruments. If you disagree, make the option to place any instrument in any of the tree locations. [Ref. IFR Trainer] • My guess, however I could be wrong, it’s general aviation students/pilots or CFIs using this app. Having to press twice to achieve a standard rate of 3 degrees per second is distractive. Put an option in Settings to set the default to match the pilot’s preference. ! Based upon the Law of Primacy, train the student’s eyes, motions, and thinking (even with simple trainers) according to norms/standards from the very beginning. Negative Transfer of Learning is expensive! “It’s an iPad typically held in the left/right hand” is a poor excuse. ! “This is not a flight simulator” is not an excuse for making something that could have been made otherwise and better with a little research, foresight and testing by a few CFIs / CFI-Is.

Updated for iOS 11

Thanks for keeping this app alive with an update for 64bit!

$5 is a lot of money for an app that hasn't been updated to work with the new iOS

Not bad

Needs a bearing pointer to the station in conjunction with the HSI
