Which engine does the Vigilant use?

The Vigilant, specifically the Vigilant T1, is powered by a Grob G2500 piston engine. This aircraft is a motor glider, which means it can fly using its engine or glide without engine power, relying on thermals and other atmospheric conditions. The Grob G2500 provides the necessary thrust for takeoff and climb, allowing pilots to reach altitude where they can then utilize its gliding capabilities effectively.

Understanding the engine type is crucial for various operational scenarios, including performance calculations and maintenance requirements. While the Vigilant is equipped with a piston engine, it is designed for a specific role that combines the elements of powered flight with gliding, which is an important aspect of airmanship training. The other options listed correspond to aircraft types or designs that do not relate to the Vigilant's actual configuration.
