iFly Weight & Balance

Your aircraft, in your hand. Signal not required.

Add your passengers, baggage, takeoff fuel and landing fuel. That is the whole job. iFly arrives pre-configured to your exact aircraft, so there is nothing to program before your first flight.

Free on the App Store — requires iOS 17.0 or later.

No internet required

Works at any FBO, any ramp, any altitude — offline by design.

Licensed to your tail

Tied to you and your aircraft serial number, not to a device.

iPad and iPhone

The same calculation on either, with a layout built for each.

The workflow

Four inputs. That's the job.

Even the most complex weight and balance scenario resolves in a matter of seconds.

01

Add occupants

Crew and passengers, actual or standard weights. Crew movement is handled for you.
02

Add baggage

Cargo by compartment, laid out the way your aircraft is actually loaded.
03

Add fuel

Takeoff and landing fuel. iFly models the exact burn sequence of your fuel system.
04

Read the answer

Takeoff, landing and zero-fuel weights, with the CG plotted live against your envelope.

Capabilities

Built for the way flight departments actually operate.

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, and licenses it to you and your aircraft serial number.

Violations are impossible to miss

Are you too far forward? The forward CG limit turns red. Stay within limits and it stays black. There is no interpreting a number against a table — the envelope tells you directly.

Exact fuel burn sequence

Complex fuel systems do not burn evenly, and the CG moves as they drain. iFly depicts the exact fuel burn sequence of your aircraft rather than a straight-line approximation.

Dynamic curtailment

iFly supports dynamic curtailing of the CG envelope as prescribed in AC 120-27F and applicable Operations Specifications — recalculated per flight, not fixed at the worst case.
