Frequently asked questions

Add your passengers, baggage, takeoff fuel and landing fuel. That is the entire workflow. The software arrives pre-configured with your aircraft specifications, so even the most complex weight and balance scenario resolves in a matter of seconds.

No. The software is your actual aircraft. There are no CG limits to program and no fuel moment data to enter — American Aeronautics customizes the software to your exact aircraft specifications before you receive it.

No internet connection is required. iFly calculates on the device, so it works at any FBO, on any ramp, and at any altitude.

You can install it on as many iPads and iPhones as you like. There is no limit. The license subscription includes unlimited updates and an unlimited device install license.

Yes. iFly supports dynamic curtailing of the CG envelope as prescribed in AC 120-27F and applicable Operations Specifications.

Yes. The iFly software depicts the exact fuel burn sequence of your aircraft rather than a straight-line approximation, which matters when the center of gravity moves as the tanks drain.

We build weight and balance solutions for all aircraft. If you have a Piper Cub or a Boeing 747 we have a system for you. We even support many aircraft with custom modifications.

Calculator systems fall into the same category as electronic computers, hand-held calculators and flight computers. They require no STC approval, as they are simply calculators.

American Aeronautics has been approved by every FSDO in the U.S. at least once, most many times.

Maximum Allowable Takeoff Weight is limited by whichever is most restrictive: the certificated weight, climb and brake energy limits, runway length available, or obstacle clearance requirements.

Maximum Allowable Landing Weight is determined by the certificated landing weight, approach climb and brake energy limits, or the runway length available — whichever is most restrictive.

FAR § 135.63 requires operators of multiengine aircraft to maintain a load manifest documenting the number of passengers, total loaded weight, maximum allowable takeoff weight, center of gravity limits, aircraft registration, origin and destination, and crew assignments.
