A reactive wind shear detection system is activated by the aircraft flying into an area with a wind shear condition of sufficient force to pose a hazard to the aircraft. A predictive wind shear detection system is activated by the presence of a wind shear condition ahead of the aircraft. In 1988, the U.S. Federal Aviation Administration (FAA ...
Wind shear refers to the variation of wind velocity over either horizontal or vertical distances. Airplane pilots generally regard significant wind shear to be a horizontal change in airspeed of 30 knots (15 m/s) for light aircraft, and near 45 knots (23 m/s) for airliners at flight altitude. [3]
Pilots may decide whether to land (or conduct a missed approach) after wind shear alerts are issued. LLWAS wind shear alerts are defined as wind speed gain or loss of between 20 and 30 knots aligned with the active runway direction. "Low level" refers to altitudes of 2,000 ft (610 m) or less above ground level (AGL).
The aircraft will be used to study the northern polar vortex and its influence on global weather patterns. [2] It has already surpassed the sub-sonic altitude record set in 1989 by a Lockheed U-2. The program also hopes to beat the 85,069 ft altitude record set in 1975 by a Lockheed SR-71 Blackbird. [3] The aircraft is made from composites.
The Grob G 520 ‘EGRETT’ is a turboprop-powered long-endurance, high-altitude reconnaissance and surveillance aircraft designed and produced by the German aircraft manufacturer Grob Aircraft. Since September 1988, it has been the holder of several world records relating to altitude and time to climb.
Best Off Aviation Skyranger being tied down at Sun 'n Fun 2006 Skyranger cockpit with optional extended panel. The Best Off Skyranger is a French-designed two-seat ultralight utility aircraft, produced by Best Off, of Toulouse. It is a high-wing conventional monoplane with tricycle undercarriage, and of fabric-covered tubular construction. [1] [2]
On December 2, 2020, Textron updated the King Air 200 series with the 260, with deliveries expected in early 2021. The model has an improved autothrottle, a Multi-Scan weather radar, a range of 1,720 nmi (3,190 km) and a top cruise speed of 310 kn (570 km/h) with up to nine passengers. [30]
The prototype aircraft (registered N3621G) first flew on May 1, 1962 [2] at Torrance. A second prototype flew in November 1964 but crashed a few weeks later due to an in-flight airframe failure. [3] A static test aircraft and two more aircraft were built for testing which resulted in the award of FAA type certificate A9WE on December 20, 1966. [2]
