Air Navigation Free app good for
You should upgrade to a moveable compass without a nav point to use whenever
Works great and is very useful. Works like the real instruments if you understand how they work.
Works really well and is accurate. Cant beat it or the "price". Thank you for doing such a great job.
Note that there is a manual on the developers website (for the Pro version) that addresses most of the critical comments in other reviews. No stability issues for me on iPhone 4. Not sure about currency of database, but it has good info for the airports near me except for comm frequencies for small fields (not inaccurate, just missing sometimes).
There is a bug with opening the list of navaids, but re-opening the list several times will get it to populate (reported long ago but not corrected).
Overall a very good app. The free version makes a possible backup to a panel mount GPS. Could be used as simple primary GPS for VFR as a supplement to FAA sectionals.
The HSI view is very nice. Setting the CDI needle to align with the runway heading provides excellent orientation when approaching and following a traffic pattern.
I have been unable to find any good HSI app except this one. Id pay for it if it had a heading bug, and the ability to make a basic multi point flight plan or load the fixes on a US approach plate. The developer has a full featured planing app but I already pay for and use Foreflight so I dont need that. However, it lacks an HSI. If the developer reads this, Id push this app to my students if those few items were added, even pay for it.
Some bad moments
The app is a good concept but the database leaves little to be desired. For Nevada in the USA, Winnemucca and Ely? Get real. Nobody has been to either places in the last century! What happened to BLD and LAS VORs? Why arent they in your database? Two of the most important VORs in Nevada. Reno? Mormon Mesa? VORS... NDBs are all gone. I deleted the app. sorry..
For some reason it wont find the GPS position. Other apps work but his one just wont.
This app sounds pretty cool, but it is missing so many nav aids and has no airports so it is pretty much worthless. Well for free it is worthless. As a pilot I recommend you not waste your memory with this app.
I like the idea, and it does have promise, but right now its hardly even worth the effort to load it and try it. Very, verrrry limited database; I mean, heck, nothing for PVD?
Im running this app on my 3GS, which has a decent gps chipset and a built in magnetometer. So why doesnt the compass know which way Im facing when I am indoors? Why dont the nav displays depict the correct bearings/radials? Cant be helped in non-S model iPhones, but apps like this are where the 3GS really shines. Cmon Mr developer, do some of that objective C stuff! Id have alteady bought your "Pro" version if youd got the 3GS features enabled.
Ive used this app for a long time and until this last update thought it was mostly good. Great concept, just missing navaids. With the latest update the developer went overboard. While there is every published vor and ndb (which is all the app was missing) there is now every grass strip someone has landed an airplane at in the last 50 years. I dont mind seeing a few private use airports as ling as they are listed on a sectional chart. If you want every 500 foot strip of grass, great. But give me the option to filter it out and browse by private airports, public airports, and navaids.
Its great that the app launches 25x faster, but it crashes far more often than before. If I ever need this to get me home in the clouds when my electrical system goes out Id like to know I can count on it to open and stay open.
Fix those two things and Ill return my review to the 5 stars it once was.
