2021年9月24日 · This module presents the airplane flap and slat systems with the following outline: Overview, Primary mode, Secondary mode, Alternate mode, Non-normal operations. Courses are constantly monitored and updated when …

BOEING 787 FULL PILOT TRAINING COURSE STEP BY STEP. Flap and Slat Modes. There are three modes of flap and slat operation: • primary. • secondary. • alternate. In the primary mode, the flaps and slats are controlled together and positioned. using center hydraulic system motors. Autogap and flap load relief operate in the primary mode.

The Airworthiness Directive will make the compliance tasks and times given in Requirements Bulletin B787-81205-SB270051-00 RB mandatory. When more than one OPTION is given for a CONDITION, do only one of the OPTION numbers.

2022年9月19日 · Flaps And Slats Are Computer Controlled Based On Flap Lever Position And Are Powered By The Centre Hydraulic System. The Flap/Slat System Is Equipped With Autoslats, Load Relief, And Skew/Asymmetry Protection

2019年10月11日 · The FAA is adopting an airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD requires repetitive operational checks of the leading edge (LE) outboard (OB) slats and applicable on-condition actions.

2008年12月30日 · The controller, one per slat, is located within the equipment bay and attaches to the heater mat via the Transition Wire Bundle, a specially designed telescoping wiring system that extends and retracts with the slats as they open and close during flight.

The Boeing 787 Dreamliner is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. After dropping its unconventional Sonic Cruiser project, Boeing announced the conventional 7E7 on January 29, 2003, which focused largely on efficiency.

Primary mode – positions the slats and flaps hydraulically. when the primary mode fails. 1 – prevents inadvertent retraction of the slats. 20 – prevents inadvertent retraction of the flaps past the go–around position. tion occurs before the slats begin to retract. OFF – alternate flaps are deactivated. EXT –.

RET-retraction is accompished electrically and sequenced so that full flap retraction occurs before the slats begin to retract. -maximum extension is flaps 20, with slats at the midrange position. -uncommanded flap or slat motion is detected. automatically moves flaps, ailerons, spoilers and flaperons to optimize camber.

2018年6月28日 · On 777/787 aircraft, the Krueger flap seals the gap between the inboard LE slat and the engine strut. My understanding is that slats are the more effective, aerodynamically pretty design, but Krugers are easier to engineer and implement.
