Many aviation apps don’t necessarily fit into the usual categories covered here. Below are five “general” apps that handle different pilot tasks. These are not endorsements of any app.
I-Timer (free in Google Play)—This app serves as a simple timer for IFR and VFR pilots. Functions include a countdown timer in seconds, countdown in degrees for standard-rate turns, and the option to use any phone button to start and stop.
FlightWinds (free in iTunes and Google Play)—This app acts as a graphical wind component calculator. In addition to breaking the wind into headwind and crosswind components, it also alerts the pilot if a personal or aircraft wind component limitation has been exceeded.
Aviation Tools (free in Google Play)—This smartphone app offers users instant access to information including METARs, TAFs, notams, and airport/facility directories, available in eight languages. The map feature displays nearby airports; after one clicks on an airport, the app displays bearing and distance, elevation, and a link to the airport/facility directory.
Aviation Pocket Knife (free in Google Play)—Users of this smartphone app have access to tools including a unit converter, fuel calculator, and crosswind calculator.
Aircraft G Meter ($2.99 in Google Play)—This smartphone app displays G forces in the style of a standard G meter. It also keeps track of the minimum and maximum G forces that an aircraft has experienced.
