What is the general purpose of having a limitation envelope in the AFM?

• A. To regulate catering options.
• B. To define safe operating boundaries across all flight phases.
• C. To determine crew uniforms.
• D. To set cabin crew rest periods.

Answer: (B)

Limitation envelope defines safe operating boundaries for the aircraft’s performance and systems across all flight phases. It sets the maximum and minimum values for airspeed, altitude, configurations (like flaps and gear), weight and balance, engine parameters, and structural load limits. Staying within these limits protects against structural stress, control problems, and degraded performance, and it guides how flights are planned and flown from takeoff through landing. Choices about catering, crew uniforms, or rest periods aren’t part of these flight limitations; those are policy or regulatory areas, while the limitation envelope specifically governs safe flight operation.
