AUTOMATIC FLIGHT OPERATION REVIEW
AUTOLAND AVAILABILITY TEST
Note: This test must be performed while airplane is on the ground.
VHF NAV Radios ....................................................................................SET
Set both VHF NAV radios to the identical, non-local, ILS frequency.
AUTOLAND Button....................................................................................PUSH
Push the AUTOLAND button and observe the following:
NO AUTOLAND legend light flashing continuously.
Autothrottle, arm, roll and pitch mode annunciators display AUTO LND / PRE / FLT / TEST.
Radio altimeters, ADI’s and ILS indications display self-test
functions.
After approximately 50 seconds, flight mode annunciator goes blank or reverts to previous display and NO AUTOLAND legend light goes out indicating a valid test.
Note: If test is invalid, the NO AUTOLAND legend light remains on until the RESET button is pushed.
Move DFGC 1-2 switch to the opposite position and repeat the test.
VHF NAV Radios ....................................................................................SET
Captain and First Officer set desired VHF NAV frequency and course.

SELECT FLIGHT DIRECTOR / AUTOPILOT TAKEOFF MODE
Note: This procedure describes steps necessary to make a flight director
takeoff, including autopilot engagement at 1000 ft. AGL. On the
ground, the takeoff mode (TAK OFF, TAK OFF) is flight director only.
In flight, the takeoff mode is both flight director and autopilot.
Note: During flight director operation with autopilot off and autothrottles
engaged, two possible incompatible modes may be displayed if non-
normal sequence of autopilot and autothrottle modes is selected.
These incompatible mode displays are speed on throttle (IAS or MACH
SEL) and speed on pitch (IAS or MACH HOLD). The incompatibility will
be displayed on non-selected side FMA. For example: With AP off
and autothrottles engaged, if DFGC switch is in 1, pushing IAS HOLD or
MACH HOLD mode button then pushing SPD SEL or MACH SEL mode
button will cause Captain’s FMA to display “SPD __ __ __” or
“MACH __ __ __” and IAS or MACH.
Note: Items 1 through 7 should be accomplished no later than the “Flight
Guidance & TRI – SET” step on the TAXI CHECKLIST.
Flight Director Switches ........................................................................FD
Speed / Mach Select Knob ......................................................................V2
Push the SPEED / MACH SELECT knob to the first detent (FAST / SLOW) and set the computed V2 speed for takeoff. Push the SPEED / MACH SELECT knob full in and set the desired climb Mach number. Verify that the SPEED / MACH SELECT knob to the maximum (full in) detent again to display V2 speed.
Note: After electrical power interruption, initial electrical power application or after a Power Up Test, the Speed / Mach Readout will revert to 100 knots.
Heading Selector ...........................................................................SET
Set the heading selector to runway heading or the first heading after
takeoff. Bank Angle Limit Selector ...........................................15 DEGREES Altitude Select ............................................................. SET / ARMED
Rotate the ALTITUDE SELECT knob to the initial level off altitude and
pull out on the knob to arm the selected altitude. ALT will be
displayed on both FMA’s.
(Continued)
TRI ................................................................................................SET
Push T.O. / FLEX on the Thrust Rating Indicator (TRI) and verify the maximum limit indexes (chevrons) on the EPR gages. Indicate the same value as the TRI Readout.
Note: If T.O. / FLEX is not used for takeoff, set 00°C in the Assumed Temperature Readout.
TO/GA Button............................................................................PUSH
Push either TO/GA button on either throttle. Verify that the roll and pitch windows in both FMA’s read TAK-OFF, TAKE-OFF. The flight director command bars will command wings level and level flight. The FAST / SLOW indicators will indicate full SLOW. The flight director command bars and FAST / SLOW indicators are not valid until after rotation. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：MD-80 Flight Manual 麦道80飞行手册 2(140)
