dimitrischal Posted August 3, 2017 Posted August 3, 2017 Well in civilian aviation we have readings in the cockpit so we don't do this. It's a flight crew thing only. I stand corrected.
Eagle7907 Posted August 10, 2017 Posted August 10, 2017 why speedbrakes are fanned out during cold start? Interesting that the speed brakes don't gravity fall when hydraulic pressure goes to nil.

Bulldog_1 Posted October 19, 2017 Posted October 19, 2017 I fly T-38's and it is procedure to have speed brakes extended and gear doors manually extended after landing for maintenance purposes. After engine start it is a team effort between crew chief and pilot to test all flight controls for proper movement (trim, stabs [including trim disconnect at max deflection], ailerons, rudder, speed brake operation, flaps [all configurations], and pitot heat). We cannot see well behind us so the crew chief moves his arms to indicate how flight controls are moving and checks to make sure they are operating and moving correctly. Habu This is 100% correct. :thumbup: DELL OptiPlex AIO 7410: i5-12500T 2.00GHz: 2TB SSD: 64GB RAM: UHD 770 1920x1080 @ 60Hz: ThrustMaster HOTAS X: IRL Retired Maintainer of the AT-38B: F-4E/G: F-15A/B/C/D: and McDonnell Douglas/Boeing Technical Advisor for the F-15C/D.

bcradio Posted October 22, 2017 Posted October 22, 2017 Slightly OT, but did you notice that the landing gear doors were closed, then opened, then closed again before taxi? How's that work?
dolfo Posted October 22, 2017 Posted October 22, 2017 (edited) Slightly OT, but did you notice that the landing gear doors were closed, then opened, then closed again before taxi? How's that work? Gear doors are closed during normal operations, including after landing. They can be released for inspection using a switch on the right gear well, and this is normally done for preflight checks. You can observe gear doors are open before engine start, and they close as hydraulics pressurise during engine start (about 0:37). Crew chief releases them again during his walk-around (5:27), closes them at 7:27. Edited October 22, 2017 by dolfo
