At what speed does the lead smoothly raise the nose prior to rotation during takeoff?

• A. 70-75 knots
• B. 75-80 knots
• C. 80-85 knots
• D. 85-90 knots

Answer: (C)

The correct choice reflects the optimal speed range for initiating the nose-up attitude just before rotation during takeoff. In aviation, particularly for multi-engine aircraft or commercial jets, the pilot needs to establish the correct speed prior to taking off to ensure safe and efficient lift-off. The range of 80-85 knots is typically determined by the aircraft's performance specifications, which take into account factors such as weight, balance, and environmental conditions. At this speed, the aircraft has sufficient airspeed over the wings to generate enough lift while maintaining control. Raising the nose at this speed helps smooth the transition from grounded to airborne, allowing for a more gradual lift-off and reducing the risk of stalling. Other options might suggest speeds that are either too low or too high, which could affect lift dynamics and control during the critical phase of takeoff. Specifically, going too low could lead to insufficient lift, while going too high might cause an abrupt ascent, leading to potential control challenges. Thus, 80-85 knots is within a safe range that balances performance and safety parameters necessary for rotation.
