737 Pilot is a set of useful tools for airline pilots flying on the Boeing 737-800. It provides a very easy way to scan your airline roster. You can see all the information about your duties, hours, salary etc… with 5 different views: day by day, week by week, month by month, year by year or with FTL. You can also get the current weather and NOTAM for any day selected in your roster, and export your flights to your calendar or to LogTen Pro. And if you want to know what you’re doing next with just one swipe, you can use the great widget included in the app which displays information about your next duty in the notification center. WARNING: in this version the only airline supported to download schedules is Ryanair. If you fly for a different airline you will only be able to create your events manually. The app includes Brake Cooling Schedule calculations for the 737-800. It also contains a tool to assist you during refueling operations (expected fueling time, expected quantity in each tank, x-check actual liters delivered against expected liters). A list of the IATA and airline specific delay codes is provided with a very convenient search feature. Finally, a non-exhaustive list of airports is available with details about each airport. You can manually add new airports to this list. More features to come in future versions!
