Quick Reference

Common aircraft W&B reference points:

Aircraft	Fwd CG	Aft CG	Max Wt
C172S	35.0"	47.3"	2,550 lbs
C182T	36.5"	47.2"	3,100 lbs
PA-28-181	82.0"	93.0"	2,550 lbs

*Always verify with your aircraft's POH/AFM

Understanding Weight & Balance

Why It Matters

Proper weight and balance is critical for safe flight. An overweight aircraft requires more runway, climbs slower, and may not clear obstacles. An out-of-balance aircraft may be difficult or impossible to control.

Key Formulas

Moment = Weight x Arm

CG = Total Moment / Total Weight

Useful Load = Max Gross Weight - Empty Weight

Effects of CG Position

Forward CG: More stable, higher stall speed, more elevator authority needed
Aft CG: Less stable, lower stall speed, reduced elevator authority
