What needs to be turned off prior to takeoff?

Before takeoff, it's necessary to ensure that specific systems are appropriately configured for safe operation. One of these systems is Nosewheel Steering (NWS). Turning off the nosewheel steering prior to takeoff allows pilots to maintain a clear and unobstructed control over the aircraft during taxi and takeoff phases. It helps in preventing accidental steering inputs that could lead to loss of control, particularly during high-speed taxiing or rotation.

In practice, this is a common procedure in many aircraft to ensure that the nosewheel is in a fixed position, allowing the main landing gear to guide the aircraft's movement more smoothly during takeoff. Properly managing the nosewheel steering is part of the wider safety checks that pilots perform to ensure that the aircraft is fully prepared for departure.

The other options, such as the landing gear and flaps, must be configured correctly and remain operational during takeoff. Power to the engines must also be engaged to facilitate takeoff, making those options unsuitable.
