SYSTEMS Flashcards
(34 cards)
If windshear is encountered during an ILS approach, what will the FD command?
Glideslope and LOC; no windshear guidance will be provided until TO/GA is pressed.
The STAB OUT OF TRIM (amber) light is armed when?___________ Illuminated when?_____________
A/P engaged_______A/P is not trimming the stabilizer properly.
After the VOR/LOC and G/S are both captured, the APP mode can be exited by: _______.
pushing a TO/GA switch,
disengaging A/P and turning off both F/D switches,
retuning a VHF NAV receiver.
The Bank Angle Selector (rotate) sets maximum bank angle for AFDS operation in what modes?
HDG SEL or VOR modes
The Speed Trim improves flight characteristics during manual flight operations at ___, ___, ___, and ___.
Low Airspeed, Low Gross Weight, Aft center of gravity, and high thrust.
How many degrees of control wheel displacement initiates spoiler deflection?
When the control wheel is displaced more than approximately 10 degrees (1.6 units), spoiler deflection is initiated.
What happens when a FLT CONTROL switch is positioned to STBY RUD?
It activates the Standby Hydraulic System and opens the Standby Rudder Shutoff Valve (allowing Standby Hydraulic System pressure to the Standby Rudder PCU).
In the MAX, the rudder pressure will return to normal system operating pressure when:
An engine failure is detected or with both engines operating, airspeed is reduced below approx. 132 kts.
In the MAX, a SPOILERS (amber) Light, indicates the Spoiler Control Electronic Unit has discovered what?
A Spoiler System Fault.
The STANDBY PWR OFF (amber) light when illuminated, indicates one or more of the following busses are unpowered: ______ or ______ or _______
AC Standby Bus or DC Standby Bus or Battery Bus
When does the BAT DISCHARGE light (amber) illuminate?
When excessive battery discharge is detected on the main battery and/or auxiliary battery.
When will the Generator DRIVE (amber) light illuminate?
When there is a IDG failure
Engine shutdown
IDG disconnected by activation of the DISCONNECT switch
IDG auto-decouple due to high oil temperature (182 C).
How long will two fully-charged batteries provide standby power?
Two fully-charged batteries have sufficient capacity to provide standby power for a minimum of 60 minutes.
What does the BUS TRANSFER switch, in the AUTO (guarded) position, allow?
Allows the Bus Tie Breakers (BTB) to operate automatically to maintain power to AC transfer busses from any operating generator or external power.
The Center Switch on the EFIS control Panel must be in which mode for the VSD to display?
MAP
The AOA Disagree Alert (amber) indicates the left and right AOA values disagree by more than ____ for more than ____ continuous seconds.
10°, 10
When does the ALTITUDE DISAGREE (amber) alert appear?
When CA and FO altitude indications disagree by more than 200 ft for more than 5 continuous seconds.
A vertical (amber) bar extending up from the top of the Minimum Speed Bar indicates what on the PFD?
Minimum Maneuvering (Vmvr) Speed
How is the HGS controlled on the MAX?
MCDU
The purpose of the PTU is to provide Hydraulic System B fluid at a flow rate (approximately 6.5 GPM) and pressure sufficient to provide normal rates of operations for the ______ and ______ in the event the Hydraulic System B Engine-Drive Pump output press drops below a specific value.
Autoslats Leading Edge Devices (LED)
When is the automatic operation for Standby Hydraulic System initiated?
When flaps are extended
Aircraft is airborne, or wheel speed greater than 60 kts,
Loss of System A or B while FLT CONTROL switch positioned to ON - OR - the main PCU Force Fight Monitor (FFM) trips.
What pressurizes both System A and System B hydraulic reservoirs?
Regulated Bleed Air
When do the letters RF (white) appear?
REFILL (RF) indication is displayed (white) when hydraulic quantity is below 76%. Valid only when aircraft is on ground with both engines shutdown or after landing with flaps up during taxi-in.
How do you display the Hydraulics in the MAX?
MFD SYS Button
