first production single-seater Typhoon multi-role aircraft, designated GS002,
intended for the German Air Force, Luftwaffe, demonstrated Automatic Low-Speed
Recovery (ALSR) capability at EADS Military Aircraft Flight Test Center in
Manching, Germany, in late October 2004.
The Typhoon aircraft features a quadruple fly-by-wire flight control system,
which provides the aircraft its outstanding maneuverability and considerably
reduces workload coupled with its ease of handling characteristics. ALSR is the
most important trait of its carefree handling functionalities.
ALSR as an integral element of the flight control system prevents Typhoon
departing from controlled flight at very low speeds and high angles of attack.
When a low-speed situation occurs ALSR raises an audible and visual low-speed
warning. Thus the pilot will have enough time to recover the aircraft manually.
It this doesn't happen, the ALSR can take control of the aircraft engaging the
engines with the maximum dry power and returning the aircraft to a safe flight
condition. In that event, depending on the altitude the ALSR can either execute
a push, pull or knife-over maneuver.
During the flight test, the test pilot Karl-Heinz Mai put the aircraft at low
speed with a 70-degree nose-up attitude and power idle. Then the ALSR reacted in
a impressive way recovering the aircraft to a safe flight condition as expected.
The ALSR in conjunction with the Flight Control System (FCS) worked flawlessly.
It has been reported that the F-35 Joint Strike Fighter will integrate a similar
capability. The aircraft might fly back by its own means to the operating
airfield if the F-35 pilot suffers incapacitating damage during a combat
