FlyBy Nav 4+

I have been looking for an app like this for some time. Very useful for quick trip calculations and charter quotes. Thanks for making this available.

I have used palm versions of this program for years, and now that it is available for the I-phone I can finally put my palm to rest. This I-phone version is easier to use and way more intuitive. I love the fact that I can show my crew a map of where we are going and the new expanded worldwide data base makes it easy to find destinations, waypoints and navaids. I highly recommend it.

Have used the PRO version for years on my (modified) Palm LifeDrive. In this version, you may only use two waypoints, However, if you have a trip with several waypoints, you may put them in one after the other, creating the navlog as you go. The PRO version would allow one to create the entire navigation log in one shot.

Once you have the legs stored, you can change info for any given leg. EG: A descent from one altitude to another might need a change in the wind vector. No problem! Just type it in!

Magnetic variation changes all the time. Ease of access to any given waypoint. I had one waypoint whose default values was 22 degrees East, but it's current value is 18.5 degrees. Bingo! just change it out. (The app will "warn you" about the change, but, caveat emptor!)

My usual procedure is to create the nav log first, with no wind applied. With an UP TO DATE chart you just make sure that the magnetic track shown in the navlog is, at least within a 'couple of degrees. (Usually, if you've made sure the variation in the waypoints concerned are up to date, it's bang on.)

When helping out with private pilot students, we must make sure they learn the basics first, as is normal. Instructors can give them the problem and let them sweat it out, while Fly by Nav will make short work of the problem, and he may drink coffee 'till he/she bursts.

My hope is that we will see the PRO version added to the app store. IMHO, the time it saves is worth $
