Aircraft Profile Manager
Save aircraft profiles with empty weight, arm, and envelope data so you can reuse them for future flights.
Why Pilots Use This
Weight and balance is not optional — the FAA requires pilots to verify that the aircraft is within weight and CG limits before every flight. An overloaded or improperly balanced aircraft has degraded performance, reduced stability, and can become uncontrollable in certain flight conditions.
- FAA requires W&B verification before every flight (14 CFR 91.103)
- Weight and balance problems are a leading cause of general aviation accidents
- CG envelope questions are guaranteed on the FAA Private Pilot knowledge exam
