A propulsion system coupled to a vehicle. The system includes an ejector having an outlet structure out of which propulsive fluid flows at a predetermined adjustable velocity. A control surface having a leading edge is located directly downstream of the outlet structure such that propulsive fluid from the ejector flows over the control surface.

A flight augmentation system with optical sensors to capture information from aircraft instruments. The system may determine a status of the aircraft based on the captured information and provide guidance to an operator. The system may collect long term data and determine an operational history of a pilot or an aircraft. The system may provide instruction based on the data or provide to interested third parties.
