Excellent app for Instructors

This app is excellent for Instructors to use when teaching VOR, HSI, RMI and NDBs. It is a visual tool to help students earn the principal methods to do when intercepting Navaids. Highly recommended this app

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

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.

Response from developer

Hi, I'm sorry that you find the app unuseful. The OBS, in fact, ticks once per degree like you said. This is consistent with the way the OBS knob works in many modern, non-analog, VOR displays. Please feel free to contact me if you have any further concerns.

Disappointed

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.

Buggy and not intuitive

Better IFR trainers out there for less money - wish I could get my money back

Excellent, and it has an RBI!

Wonderful as an instructing tool to introduce my students to VOR and NDB tracking and interception. Particularly useful is the Relative Bearing Indicator (RBI). Lots of training aircraft do not have a more expensive RMI, and if, like me, you teach NOT to use the rotatable compass card on the RBI (if you have one) because it’s too easy to forget to ‘twist’ it, then this I think is the ONLY app that offers a pure RBI.

Thank you for this nice review 👍

While I don't disagree with those who suggest that this has little use for those who don't know how a VOR or ADF operate, I would suggest that most apps have little value for those who don't know what they are for. For those who DO know how a VOR or ADF works, this is a great practise app. I use it for both practising and helping my students learn things like VOR intercepts, hold entries and getting established on an approach. The ability to turn off and on the plane is VERY helpful because it makes the user actually USE the instruments. Track trails then help to confirm if I got it right. The speed controller allows me to customize the tool for my needs. The time is a very thoughtful touch making it possible to practise Time-Turn-Throttle-Talk although you have to talk to yourself. :-)
I would suggest this for all instructors and IFR students.

iOS 11

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

Response from developer

The App has been updated and works on iOS 11. You may be experiencing a problem as a result of updating the app after updgrading iOS. If thats the case deleting the app and reinstalling it could solve the issue. Please let me know if you are still experiencing a problem. Safe flying!

CFI-I Review (Updated)

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.

Thank you for the detailed review. I am considering updates to address some of the issues you mentioned. 1. I've tested it on different devices. Std. rate turn in the app is correct at 3º per second. Please note that the turn buttons are multi-rate. Each press on the button increments the rate starting at 0.5 to 2.5 x Standard Rate. You might have hit the button only once, which resulted in a 1/2 standard rate turn. A second tap on the button will produce 1x standard rate. 2. Position of the panel is configurable via the settings screen. The reason the displays are on the right by default is that most users are right-handed. Therefore, it is much easier to control the instruments from the right side for most users. However, you can change this on the settings screen. 3. I'm not sure why you'd expect the heading indicator on top. In a traditional instrument panel, the HI is on the bottom row and the VOR displays are to the right of the primary instruments. In the app, the heading indicator doubles as a control for the airplane's heading. The middle position on the screen is easier to control. I will look into having an option to reconfigure the position of the instruments in a future version if more users are interested. 4. This is a very specific configuration that may work for one user but not for another. I'm considering adding an option to save airplane and navaid positions for quick scenario setup. 5. Not sure why you'd expect specifically 5 NM, but it's a good idea to add an option of configuring grid spacing in the settings. I'll work on this for a future update. 6. Since the controls are being so sensitive, I will work to improve this soon. 7. That is a good idea for an improvement, thanks. 8. Please keep in mind that Nav Trainer is not a flight simulator, and therefore doesn't have all the instruments you'll find in an actual airplane. That would be a distraction from the scope of the app of training pilots on the use of radio navaids. However, this may be a nice idea for an add-on in the future. I appreciate the feedback, and hope I've addressed some of your concerns. Safe flying!
