I currently have a couple products available to the general and commercial aviation community. More will be forthcoming in the near future.
Cellphone Applications:
Aircraft Weight Limits (Free): Calculates the payload limits for a selection of aircraft types based on the BEW, Fuel Loading, Taxi Fuel and Crew Weight for the leg.
CANPA Approach (Free): Calculates a CANPA (Constant Angle Non-Precision Approach) based on an approach fix giving check heights to the fix.
E6B Calculator: Combines the functions of a standard hand held flight calculator (e.g. CX2), a wizz wheel plus multiple other useful functions and calculations.
FDP Calculator (Free): Calculates the maximum allowable FDP and latest scheduled sign-off time based on the FDP limits for 2 pilots acclimatised to local time.
* The cellphone based applications will run on any java enabled handset in either "online" or "flight safe" mode
