RAF Airmanship Practice Exam 2026 - Free Airmanship Practice Questions and Study Guide

The correct choice regarding the engine that powers the Griffin helicopter is the option referring to one Pratt and Whitney Turbo. The Griffin helicopter, specifically the Griffin HT1 variant used by the RAF, is designed to be powered by a Pratt & Whitney Canada PT6A-113 engine, which is known for its reliability and performance in a variety of conditions. This engine provides the necessary power and efficiency that is essential for the helicopter's operations.

The other options refer to different types or configurations of engines that are not utilized in the Griffin helicopter. For example, Turbomeca Arriel engines are typically found in other helicopter models, while Avro Lycoming TSS-L-712 Turboshafts are not related to the Griffin. Similarly, the mention of a Rolls-Royce Turbomeca is a mischaracterization of the specific engine used in the Griffin. Thus, the choice identifying the Pratt and Whitney Turbo engine is accurately aligned with the specifications of the Griffin helicopter.
