![]() ![]() There is no restriction on the speed at which the speedbrakes may be used (onĪirtests they are deployed at 360/M0.84) however the resultant position is aīRAKE TEST buttons are only found on -1/200's and old -300's. The SPEEDBRAKE DO NOT ARM light in-flight does not preclude Because with the thrust levers closed, the ground spoilers will deploy as well. If not armed, the speedbrakes will deploy when reverse thrust is selected.ĭo not use speedbrakes in-flight if you have had to manually over-ride the gear to retract it. Thrust levers are at idle and any two wheels have spun up or right gear isĬompressed. On landing, if armed, all spoilers will deploy when the Only the outboard flight spoilers are powered by hydraulic Spoilers will continue to operate with speedbrake deployed. 1/2/3/4/500 4 -NG's) augment the ailerons and are powered by hydraulic systemĪ (inboard) & B (outboard). Of photographs just how much extra drag ground spoilers will give overħ37-400 Flight and ground spoiler deployment on landing Lever Will Not Move Up After Takeoff" you must not use speedbrake inĬase the ground spoilers deploy in-flight. Problem that might be due to a faulty air-ground sensor eg QRH "Gear This is why if you have any sort of technical NB In the bottom two photographs the speedbrake lever was only at theįlight detent position but because the aircraft was on the ground the Recommend that speedbrake is not used below 1000 feet for this reason. Which is why the roll rate is increased when speedbrake is used. This property of the spoilers on both wings to respond to roll inputs is Notice that even withįull speedbrake applied the spoilers still rise on the downgoing wing. Speedbrake applied, not only do the spoilers on the down-going wing riseīut also the spoilers on the up-going wing fall. With speedbrakeĭown, the spoiler simply rises on the down-going wing with aileron. With various combinations of aileron and speed brake. Is prohibited because of excessive roll when the a/p is disconnected.Ībove series of photographs (737-300) show how the flight spoilers move Use of aileron trim with the autopilot engaged There are two aileron trim switches to prevent spuriousĮlectrical signals from applying trim. (Ref AAIB Bulletin No: 2/97)Īileron trim moves the neutral position via the feel &Ĭentering mechanism. The maximum aileron movement which can be achieved by the pilot is about 20°, which requires a control wheel input of about 82°. The maximum roll control deflection which the autopilot can achieve is, by design, about 4.5° of aileron movement (a control wheel movement of about 20°), depending on the stimulus. There are balance tabs and balance panels on both ailerons. The aileron system jams, the co-pilots wheel can be used to move the spoilers Ifīoth hyd should fail, manual reversion is available from both control wheels.

This one covers roll control and also speedbrakes. This is the first in of a 3-part series on Boeing 737 Flight Controls. Check out the Lisa Akoya as well as the Robin 401 on LetsFlyVFR You tube Channel for more.Roll Flight Controls - Roll and Speedbrakes I have personally made a few videos in the Lisa Akoya and they were a lot of fun. Its great to have the option to land on a fixed runway or a lake or sea runway. We also have been given the Lisa Akoya seaplane for X Plane 11 to enjoy the waterways and back blocks of the sim. Included us the Garmin G1000 avionics package to make this aircraft feel ultra modern. The aircraft is tremendous fun to fly and comes with great quality cockpit textures and flight model. They have gifted the community a number of high quality freeware aircraft like the French designed single engine Robin 401, four place aircraft. There are some fantastic freeware aircraft that were previously payware available.Īerobask is a great producer of both payware and freeware X Plane 11 aircraft. If you are looking for some new great X Plane 11 freeware aircraft then x plane 11 free addons are plentiful. ![]()
