For aircraft owners
Pick your type's handbook, enter your airplane's empty weight and arm, and load it the way you'll fly. Over gross or outside the envelope, it refuses and says why. Takeoff and landing distance come from the same handbook.
One aircraft, its handbook and its weight and balance are free. Reference only, not an FAA-approved flight manual.
Verified handbooks you can pick for your airplane
The 1967 Mooney M20F's handbook prints no table of loading arms, so its weight and balance stays off. Its takeoff and landing calculators still work.
Demo load on this airplane's own weighing (1,422.3 lb at 37.4 in). Reference only, not the approved flight manual.
Demo on the 1967 Cessna 172H showcase handbook and that airplane's weighing. Yours runs on its own type's handbook and its own weighing.
Each refusal names the limit it broke and by how much. Where there's nothing honest to compute from, it says so instead of showing a number. Reference only, not an FAA-approved flight manual.
Refused, with how far over it is, to the tenth of a pound.
Refused when the CG sits forward or aft of the limit at that weight. It's plotted as the fuel burns, so a load that drifts out on the way down shows too.
Refused against the placard, compartment by compartment where the handbook has two.
No CG at all until you enter your airplane's empty weight and arm. It never borrows another airplane's weighing.
The calculators read the same handbook as the weight and balance: its own takeoff and landing tables, for the weight and conditions you enter.
Reference only, not an FAA-approved flight manual. Check every figure against the flight manual for your serial number.
Density altitude about 7,921 ft, from the pressure altitude and temperature.
Takeoff data, 1967 Owner's Manual. The handbook's own notes, applied as printed:
Reference only, not an FAA-approved flight manual.
Demo on the 1967 Cessna 172H showcase handbook. Try a tailwind: this handbook prints no correction for one, and the engine says so rather than treating it as calm.
For each of these the engine reproduces the handbook's published tables in automated checks, run on every change. Pick yours when you add your airplane, then enter its weighing.
Not tabulated in our copy: glide distance. That calculator stays off for this type.

No table of loading arms in its handbook, so weight and balance stays off.
How each one is checked, and the handbooks that aren't verified yet: Verification
One aircraft, its handbook and its weight and balance cost nothing, and neither does getting your data out.
Just you and your airplane.
One aircraft of your own with its handbook and weight and balance, a personal logbook, and every export.
Your airplane and your partners.
1 aircraft · unlimited partners · cost-sharing
One airplane shared with partners: scheduling, check-out and check-in, and cost-sharing by Hobbs or tach.
More than one airplane of your own.
Up to 25 aircraft of your own, each with its handbook and weight and balance.
Verified means the engine reproduces the published tables of that type's handbook. It doesn't mean those numbers fit your airplane: your empty weight, equipment and modifications come from your own records, and the flight manual for your serial number, its placards and your current weight and balance record are the authority.
One aircraft, its handbook and its weight and balance are free. Bring your partners when you're ready.
