Note: This checklist step applies only to aircraft with autobrake system
installed. Lift Spoiler lever into ARM position. Rotate Auto Brake selector to T.O. and move ARM/DISARM switch to ARM. Check AUTO SPOILER DO NOT USE light is off.
If rejected takeoff is initiated above 70 knots (nominal) with flaps at a takeoff setting, nose wheel on ground and throttles retarded, activation of reverse thrust levers will initiate deployment of ground spoilers and full braking will be applied after spoilers are deployed. (Full braking will also occur with manual deployment of ground spoilers.) If initiation speed is less than 70 knots (nominal), automatic braking sufficient to achieve “minimum” deceleration will be applied. In this event manual braking may be required when remaining runway distance is short. Pilot takeover of the brakes is available at any time by applying the brake pedals.
Note: The actual speed switch point is nominally 70 knots ground speed. If an RTO is initiated between 65 to 75 knots, ABS may apply either minimum or maximum braking. Also between 65 and 75 knots, if an RTO is initiated when speed switches within the ABS box are in disagreement a disarm of the ABS will occur. (ABS, AUTOBRAKE FAIL, and MASTER CAUTION lights will illuminate).
Caution: If during a high speed taxi, above 70 knots, the spoilers are deployed, (manually or by thrust reverser, flaps in takeoff and ABS armed) maximum braking may occur.
Note: Operation of the spoilers in the rejected takeoff mode requires the following:
-
Anti-skid operational and armed.
-
Autobrake system operational, armed, and set to T.O.
-
Spoiler system operational with spoiler lever armed.
It is Continental policy that the autobrake system (if operational) will be armed for all takeoffs in ABS equipped aircraft. For takeoff with a non-operational autobrake system in an ABS equipped
aircraft: Set autobrake selector to OFF, and do not arm the spoiler lever. If an RTO is required, the ground spoilers must be manually deployed by squeezing the spoiler lever, lifting to the ARM position, and pulling fully aft into the latch.
Note: This differs from aircraft without automatic RTO ground spoilers where the spoiler lever must be pulled up, fully aft, and up into the latch.
Takeoff Warning.............................. C+F .................................. CHECKED
The Captain will advance both throttles momentarily to check for a
takeoff warning horn.
Flight Guidance & TRI ..................... ..................................................SET
Verify that V2 speed is set. Verify that the initial level off altitude is selected and armed. Press either TO/GA button and confirm TAKE-OFF, TAKE-OFF annunciated in the roll and pitch windows of both FMAs.
Check that navigation equipment is operating and set for takeoff. All
warning flags should be out of view.
Pitch and roll attitude information on the flight director indicator and
standby horizon should reflect the aircraft attitude while taxiing.
The compass information displayed beneath the lubber line on the
azimuth scale of the course indicators should agree with the opposite
RMI’s. Electric compasses should agree within 4° of each other and
within 10° of the standby magnetic compass.
Set the course arrow and heading marker as required for the departure
clearance.
Verify T.O. or T.O. FLX is selected on the TRI.
Takeoff Briefing, Harness .............................................COMPLETED, ON
Prior to the first leg of the trip series, the Captain will conduct a complete departure briefing. This briefing should include, but not necessarily be limited to, a review of the following areas: 中國航空網 www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：MD-80 Flight Manual 麥道80飛行手冊 1(146)
