Which data should be checked to determine safe airspeeds, weight limits, CG envelope, and operating envelopes?

• A. Pilot's license
• B. Weather briefing
• C. Airport directory
• D. POH/AFM

Answer: (D)

Knowing safe airspeeds, weight limits, CG envelope, and operating envelopes comes from the airplane’s own official limits. The data you need is in the Pilot's Operating Handbook or Aircraft Flight Manual (POH/AFM), which gives the aeroplane’s weight limits (maximum gross weight, useful load, and center of gravity range), the CG envelope, and the operating envelope including V-speeds, maneuvering speeds, flap limits, and other critical limitations. This is the reference that ensures all performance calculations and flight planning stay within what the aircraft can safely handle. The other sources don’t provide these aircraft-specific limits. A pilot’s license shows qualification to fly but not the particular airplane’s limits. A weather briefing is about conditions, not performance or structural limits. An airport directory gives airport details and services, not the aircraft’s performance data. Always check the POH/AFM for the exact data applicable to your aircraft configuration.
