V-speeds

Weight & balance method

1. List each station's weight: empty aircraft, front seats, rear seats, baggage, fuel (gal × 6 lb for 100LL).
2. Multiply weight × arm = moment for each station.
3. Sum the weights; sum the moments.
4. Total moment ÷ total weight = CG.
5. Confirm weight is at or under max gross and CG is inside the envelope at that weight — check the envelope, not just the numbers.

Worked scenarios (including the over-gross trap case) live on the Performance & Limitations task page.

Study strategy — spaced repetition, chair flying, aircraft-specific numbers — lives on the How to Prepare page.
