CPL Aircraft General Knowledge · Mock exam

The 'Vmo' marking (if present) on a high-performance aircraft ASI represents:

• A.The speed for best rate of climb that gives maximum altitude gain per unit of time at the aircraft's current weight and configuration
• B.The minimum speed at which the aircraft may be operated in clean configuration without risk of stall in normal flight conditions
• C.The maximum operating speed — a red radial line or barber pole above which structural damage may occur
• D.The maximum landing gear extension speed above which extension would cause structural damage to the gear doors or actuating mechanism
