    I may be mistaken, however, I think the 16 hour maximum is only available with pilot concurrence. Otherwise the max FDP is 14 hours.

  • RAP calculation in question.

    by 117 User pilot

    I believe the RAP calculation is not accurate. A FCM should not be limited by Table B/C from show time. Lesser of table b/c plus 4 hours or 16 as measured from beginning of RAP for unaugmented ops.

  • Not worth your money

    by 121_driver

    This app doesn't track previous duty periods to "look back" and figure out legality of current assignments. It is easier to look at 117 tables.

  • Cumulative look back needed

    by Stuka242

    How can you say in the description that this was developed by professionals??? They should have thought about the look back first thing!! Bad app...

  • Far 117 calculator

    by Jblupilot

    Well, I can do this. I need multiple leg, multiple day and 168 day tracking like a log book that can look back and forward. Otherwise what's the point? Money here not well spent.

  • Needs work

    by Kkesp

    Does not have a cumulative function. No ability to indicate departure and arrival airport, which would be used to determine if you are acclimated or not. Please stop using the spinning wheels to select times. I do like the Earliest Report time function.

  • No option to track so far...

    by BB'er

    Where is the rolling 168 hrs in this app to keep track of my legality for the next flight?

  • Not that great

    by larhode

    Very complicated, no instructions. Have shown it to several other pilots, none of them could figure it out or get it to provide any useful information. Good idea, bad execution, don't waste your money.
