Pilot-in-command weight and balance duty
Weight and balance: PIC's legal duty, redone for every flight (TC AIM RAC 3.4.2).
Recognize effect on performance and handling, especially combined with performance-reducing factors (TC AIM RAC 3.4.2):
- Contaminated runways
- Aircraft icing
- Degraded engine performance
- Turbulence
- High ambient temperatures
- Emergencies
Weight or CG limits not observed (TC AIM RAC 3.4.2):
- Legal condition for operation not met
- Airworthiness certificate nullified
Documentation (TP 1102):
- Current W&B data carried with aircraft documentation
- Not airworthy unless loaded per that data
- Observe operational loading placards scrupulously
- PIC must know all loading information: permissible loading and its correct disposition
Report (TC AIM RAC 3.4.4):
- Preparer: crew, or another qualified person the company or operator authorizes
- Responsibility stays: PIC ensures report accurately reflects actual load
- PIC also ensures load within max allowable weight for any phase of flight
Reevaluation (PHAK ch.5):
- W&B data reevaluated often
- Certification weighing not valid indefinitely: equipment changes or modifications affect it
Trap: someone else preparing or signing the W&B paperwork does not excuse PIC from verifying it; PIC stays responsible for limits regardless of who did the math.
