.
Flight Deck Portable Oxygen bottle is 1620 psi minimum
.
Crew Oxygen bottle is 1300 psi minimum
.
Engine oil and hydraulic fluid quantities are adequate
.
Gear pins (3) are on board
.
Aircraft logbook is signed off for “R’qrd A/C Checks” and all
discrepancies cleared.
Oxygen Mask, Regulator................... C+F .............CHECKED, SET, 100%
FIRST FLIGHT OF DAY
Crew Oxygen and Mask Check:
.
Supply Toggle should be lockwired in the ON position.
.
With diluter control in 100% OXYGEN position, remove the oxygen mask from the overhead hanger and inhale several times and note that oxygen FLOW blinker is operating. Indicated pressure on crews demand regulator should continue to indicate 50 to 75 PSIG (normal range).
.
Leave diluter control in 100%.
.
Test mask/normal/emergency control NORMAL POSITION
Note: To test mask and hose assembly for possible leaks, fit mask assembly to face and move TEST MASK/NORMAL/EMERGENCY control to TEST MASK position.
Interphone Check:
Verify Boom/Mask switch on jack panel is in mask. Make a test call with
mask on interphone and verify transmission through flight deck speakers.
Return mask to overhead hanger.
OTHER FLIGHTS Crew Change Same as FIRST FLIGHT OF DAY No Crew Change Check Supply Toggle in ON position, Diluter control in 100% OXYGEN position, and indicated pressure of 50 to 75 PSIG.
CADC, Flight Director Selectors (FLOW)...................................NORMAL
FIRST FLIGHT OF DAY
Verify that the CADC selector and the flight director selector are in the NORMAL position. Check that the amber CADC and FD lights on the Captain’s and First Officer’s instrument panels are extinguished.
OTHER FLIGHTS
Same as FIRST FLIGHT OF DAY.
Voice Recorder (FFOD) ...............................................................CHECKED
FIRST FLIGHT OF DAY
Push the test button and hold for five seconds. Observe meter needle remains in green band the entire time test button is depressed. (On CVRs with a white band: momentarily push test button and observe meter needle deflects twice into white band, and drops back again.). With headset on and plugged into voice recorder test monitor jack, speak in a conversational tone and listen for same words played back after a short delay.
OTHER FLIGHTS
No test is necessary.
Electrical Panel, Emergency Power (FFOD)....................CHECKED, OFF
FIRST FLIGHT OF DAY
.
CSD disconnects normal, capped, and safety wired.
.
Move engine generator switches to RESET and ON.
.
EXT PWR and APU bus switches as required.
. AC and DC BUS X-TIE switches AUTO and OPEN.
.
Galley power on, if required. Galley power off greatly reduces electrical load on the APU allowing it to deliver more pneumatic power for air conditioning.
.
Transformer rectifier indications normal.
.
Battery switch ON and locked.
Emergency Power Check
Note: The emergency electrical power check may be accomplished any time the BATT switch is on and right AC bus or ground service bus is energized.
Verify meter selector is in BATT VOLT and rotate EMER PWR switch to ON. Observe EMER PWR IN USE light comes on and AC EMER BUS OFF and DC EMER BUS OFF lights remain off. Check for the following items:
.
HEADING and ATT flags on Captain’s instruments not in view.
.
OFF flag in F/O’s RMI not in view.
.
Comm 1 and Nav 1 radios are powered.
.
Battery voltage is 25 volts or higher.
Caution: If battery voltage is less than 25 volts, move BATT switch to
OFF. Battery must be replaced. Rotate meter selector to BATT AMP and observe 10 to 50 amps to the right. Rotate EMER PWR switch to OFF and observe EMER PWR IN USE light is off and verify battery amperage is charging in a pulsing mode to the left.
Caution: If the battery amperage indicates a steady mode to the left, it may be that the battery has not had sufficient time to charge.
The crew may continue the checklists through AFTER
START but may not move the aircraft from the gate until all
