Grob G109B / Vigilant T1 - FlyingIron Simulations
(For X-Plane)

Lightweight, Efficient & A True Thrill.


The Aircraft

The Grob G109b is a twin-seat, self-launching motor-glider developed by Grob Aircraft AG of Germany. The G109b variant first took flight in 1984 and has been used in a variety of applications since: as well as civilian use and pilot training, the aircraft was also used by the RAF from 1991-2018 (known as the Vigliant T1) to train cadets in basic flying.

Experience all that this amazing aircraft has to offer; from soaring through valleys & mountains and into the clouds, careful flight-planning, Engine Management, VFR Training, Cross-wind landings & finally experience the thrill of shutting down the 95hp Engine mid-flight and masterfully gliding back to earth for a precision landing.

Our simulation of the G109B will let you experience all this & more!
