V2 - Takeoff Safety Speed

Question 1

The take-off safety speed V2 (V2min) is the highest of:

Answer 1

• 1.1VMCA
• 1.13 VSR for 2/3 engine turboprop aeroplanes and jet aircraft without provisions for obtaining a significant reduction in the one-engine inoperative power on stall speed.
• 1.08 VSR for turboprops with more than three engines and jet aircraft with provisions for obtaining a significant reduction in the one-engine inoperative power on stall speed.
• VR plus the speed increment attained before reaching a height of 35ft above the take-off surface.
• A speed that provides adequate manoeuvring capability.
