FIRST FLIGHT OF DAY
Note: Before beginning the check of the hydraulic system, verify that the flap/slat handle is in the UP/RETR detent and that the handle is in agreement with gauge. If the handle is in any other position, contact the ground crew for clearance before moving the handle or pressurizing the hydraulic system.
.
Momentarily move the AUX HYD PUMP switch to OVRD and observe the right HYD PRESS gauge indicates a pressure increase. Move the AUX HYD PUMP switch to ON and observe the HYD PRESS gauge indicates between 2800 and 3200 PSI and the R HYD PRESS LOW light is off.
.
Move the TRANS pump switch to ON, observe the left HYD PRESS gauge indicates above 2000 PSI and the L HYD PRESS LOW light is off.
Note: If either HYD PRESS LOW light is on with normal system pressure, check the respective spoiler bypass valve is set to SPOILER ON position.
Note: If either HYD TEMP HI light is on, call maintenance.
. Check RUDDER CONTROL MANUAL light is out.
.
Check hydraulic fluid quantities indicate an adequate supply of fluid
(4.25 qts minimum).
.
Move AUX and TRANS pump switches to OFF and verify ENG hydraulic pump switches are in HI.
OTHER FLIGHTS
. Check hydraulic fluid quantities indicate an adequate supply of fluid
(4.25 quarts minimum).
Static Selectors (FLOW) ................................................................NORMAL
FIRST FLIGHT OF DAY
Verify STATIC AIR switches are in NORM.
OTHER FLIGHTS
Same as FIRST FLIGHT OF DAY.
Radar (FFOD).....................................................................CHECKED, OFF
FIRST FLIGHT OF DAY
Set the radar system controls as follows:
.
Antenna Stab Switch (If installed)........................................... ON
.
Gain.................................................................................... AUTO
.
Range Control............................................................................ 40
.
Brightness............................................................... AS DESIRED
.
Mode selector .......................................................................TEST
Note: May have to press TCAS button to bring up radar test display. Predictive Windshear System: Verify the following indications occur.
WEATHER RADAR TEST PATTERN
.
TCAS DISPLAY TEST PATTERN
SEQUENTIAL LAMP TEST FIXED TEST COMMAND
Transponder, TCAS (FFOD)...........................................CHECKED, STBY
FIRST FLIGHT OF DAY Rotate the spring-loaded function selector switch to the TEST position for one second and then release the switch. Refer to pictures on page 48.
The following should occur:
.
A test pattern will be displayed on the radar CRT that allows verification of each type of intruder symbol that can be displayed. During the test, the word TEST is displayed in the lower left corner of the display. The following symbols should be observed:
.
A resolution advisory (red square) will appear at 3 o’clock, range of two miles, 1000 feet below and flying level.
.
A traffic advisory (yellow circle) will appear at 9 o’clock, range of two miles, 200 feet below and climbing.
.
Proximity traffic (solid white diamond) will appear at 1 o’clock, range 3.6 miles, 200 feet above and descending.
.
Non-threat traffic (open white diamond) will appear at 11 o’clock, range of 3.6 miles flying level 1000 feet above.
On the RA/VSI, during the first few seconds of the test, the RA/VSI red and green circumference light (the climb/descent indicators) illuminate sequentially. The TCAS flag is in view throughout the test period. After the sequential lamp test, the red and green climb/descent lights display a fixed test command similar to a representative Resolution Advisory throughout the remainder of the system test. Should a VSI failure be detected at any time, the VSI flag will appear.
At the conclusion of a successful self-test, a synthesized voice announces:
“TCAS SYSTEM TEST OK.” Should a failure be detected during self-test, the TA display indicates the failed system component, and the audio message says: “TCAS SYSTEM TEST FAIL.”
Note: Press TCAS button to regain display range marks, if desired.
