Weight & Balance
Pure moment math. Enter the numbers from your POH — empty weight, arms, envelope corners — and we'll do the rest. No hardcoded aircraft data, because every airplane weighs different.
Stations (weight × arm)
Enter each loading station from your POH / AFM. Empty weight and arm come from the aircraft's most recent weighing.
CG envelope corners
Two or more (weight, fwd-CG, aft-CG) points from your POH's CG envelope chart. Calculator linearly interpolates between them.
Status
Enter your aircraft + envelope data
Why no aircraft presets
We deliberately don't ship hardcoded numbers for any aircraft. Every airplane's empty weight, arm, and CG envelope is unique to that tail — they shift with every equipment change and every weighing. The math is universal; the data must come from your POH / AFM and your most recent W&B record.
