Testers at Edwards AFB, Calif., have pushed the RQ-4 Global Hawk Block 20 unmanned aerial vehicle to its “fuel system limits” to ascertain just how long it could fly in the event of a missed landing, reports A1C Mike Young. The weeklong testing took place inside a weight and balance hangar at Edwards. The test team tilted the UAV at a 20-degree angle, which simulates a missed approach, requiring the aircraft to climb at a steep angle to recover. “We wanted to ensure that at the steep deck angle, the pumps would not create an engine flame out resulting in engine failure,” said 2nd Lt. Garrison Lindholm, the 773rd Test Squadron subsystem engineer.
Airmen basic rarely go on to become four-star generals, but one who did retired last week after a 42 year career that saw him rise from a lowly slick-sleeve to the head of one of the Air Force’s most important major commands.
