This incredible app just got even better with the addition of the Cost Per Hour function. Once you input your aircraft cost per hour you can then calculate the cost of each trip with wind taken into consideration. Now when the boss asks how much will it cost to go from A to B, I can give him an accurate estimate of how long it will take and how much it will cost for each LR of the trip. This is the BEST flight planning software for the price available today. I have used it since its earliest days on a PALM. Additionally the support is second to none. If you ever have a suggestion or comment, your email is returned immediately. A long time ago I suggested Fuel and Flight Time bias options to account for takeoffs, climbs, descents, and landings in order to more accurately compute actual flight times and more importantly fuel burns. I have used this software for everything from small experimental aircraft to large business jets. The accuracy is incredible especially when using the fuel bias. Can't tell you how many times the boss has asked me "how long would it take us to go from a to b"... Within seconds I have an answer. I typically leave the average wind stored for the current season and it is a great WAG. If I need more accurate flight times and fuel burns I average the winds aloft at departure and destination and insert those. Try it. You will love it.

Had previously utilized FlyBy Nav, FlyBy E6B, & FlyBy Nav Pro on an HP PDA since 2004 and am glad to see it was available for iPod/iPhone. Both the E6B & Nav are greatly improved with easy to use features such as fuel burn rates and ETE when current winds are know and added into calculations. Impressive data base of airports. Even if you are enroute destination not in data base, you can easily input the lat/long, enter, and save in your favorites. Would definitely recommend to fellow aviators. Tech support from skywritersoft and Mr Ganz is top notch. Look forward to release of FlyBy Nav Pro in iPhone iteration.

This is fast becoming my favorite flying software. I downloaded this and did some backcountry flying over the weekend and was impressed how easy it was to use. It is very intuitive and laid out with just the right info for on the go flight planning.One of the coolest features is when you save to your favorites list, it adds the airport name as well as the identifier. This is a real help if you are flying to small airports that only have three digit codes such as U87. I also fly an expermental, so being abe to add all the current info for my aircraft was way cool. Now I just go to my favorites and choose where I want to go and bingo, the route, time in flight, and fuel burn is right there. Awesome! If you`re looking for a great program to get you to where you want to go without all the hupla, this is the one to get. I highly recommend it.

Too many flight planning apps require either a WiFi connection, 3G, a logon or a subscription. FlyByNav only requires a one time fee and can be used offline!Here's what I like:Off Line Use of entire USA databaseQuickly calculate Time Enroute between airportsSaves multiple aircraft flight profilesQuick Charter QuotingQuick METAR/TAF of departure and arrival airportsOne Time Fee for Life! No SubscriptionsMy only wish is for the app to download current winds aloft for a selected cruise alititude. Although the app does allow manual input of winds aloft the info must be found somewhere else.A Must Have App!
