Pick up the incorrect statement from the following: A. In single engine aeroplanes, the engine is provided in the nose of the aircraft B. In double engine aeroplanes, one engine on either wing is placed symmetrically C. In three engine aeroplanes, two engines are placed on both wings and one engine is placed in the tail D. None of these

The correct answer is: A. In single engine aeroplanes, the engine is provided in the nose of the aircraft.

Single engine aeroplanes can have the engine mounted in the nose, on the wing, or in the tail. The location of the engine is determined by the type of aircraft and the desired performance characteristics.

For example, light aircraft often have the engine mounted in the nose because this provides good visibility for the pilot. However, this configuration can make the aircraft more susceptible to engine failure, as the loss of an engine in the nose can cause the aircraft to pitch nose-down.

Twin-engine aeroplanes typically have the engines mounted on the wings, as this provides good balance and stability. This configuration is also less susceptible to engine failure, as the loss of one engine will not cause the aircraft to pitch nose-down.

Tri-engine aeroplanes typically have one engine mounted on each wing and one engine mounted in the tail. This configuration provides good balance and stability, and it is also less susceptible to engine failure than a twin-engine configuration.

In conclusion, the statement “In single engine aeroplanes, the engine is provided in the nose of the aircraft” is incorrect. Single engine aeroplanes can have the engine mounted in the nose, on the wing, or in the tail. The location of the engine is determined by the type of aircraft and the desired performance characteristics.
