SLOD practice Flashcards
Recall the radar’s functionality during the automatic self test.
-Radar is fully operational and radiating energy when first turned on during it’s 45 second self test.
-No warm up period required.
-Quick self tests are performed after every sweep.
-Radar system fault/malfunction indications are ONLY displayed on ND
Describe the FMGCs navigation auto-tuning feature.
-Provides localizer guidance during takeoff roll for runways served by an ILS
-Auto tunes VOR and DME stations enroute for position and orientation updating
-Auto tunes the ILS frequency for final approach guidance, when an ILS approach has been loaded into the flight plan.
Recall how VOR information is displayed, and how ILS information is displayed.
VOR
-displayed on ND’s
-When respective EFIS VOR 1 or 2 selector switches placed in the VOR 1 or 2 position
-When identified by the FMS, the station’s 3 letter ident will be displayed
ILS
-displayed on PFD’s
-When respective (I)LS pushbutton is pressed
-When identified by the FMS, station’s 4 letter identifier is displayed.
Describe SELECTED guidance of the autoflight system
-Pulling the SPD/MACH knob selects specific target airspeed
-Pulling the HDG/TRK knob selects specific heading
-Pulling the altitude knob engages an open climb/descent
-Pulling the V/S / FPA knob selects a specific vertical speed or flight path angle climb
Selected guidance ALWAYS takes priority of MANAGED
Describe MANAGED guidance of the autoflight system
-Allows the autoflight system to follow commands generated by FMS
-Autoflight system complies with the lateral, vertical and target airspeed profiles defined by the FMGC’s entered into the flight plan and constraints entered by the pilot.
-MANAGED guidance is engaged or armed by momentarily pushing the respective knob on the FCU
Note: Pushing the V/S / FPA knob does not result in a MANAGED mode. This action would command in an immediate level off.
Recall how to engage and disengage the autopilot.
To Engage - select the AP1 or AP2 pb on the Flight Control Unit (FCU)
To Disengage
-Pressing the autopilot disconnect pb on either sidestick (preferred)
-Selecting the illuminated AP1 or AP2 pb on the FCU
-Displacing either sidesticks or rudder pedals
Where can you monitor the temperature of the aft cargo compartment?
ECAM COND or CRUISE pages
Recall Indications of external high pressure air being applied to the pneumatic system.
With NO internal air source being provided (i.e. APU or engine bleed air), a PSI value is displayed on the left side of the ECAM BLEED page.
Recall Indications when APU bleed air is in use.
APU Bleed valve indicates open on the ECAM bleed page
APU bleed is displayed in green on the memo section of the E/WD
Describe the G/S mode pb on the GPWS panel
G/S Mode
-Inhibits the excessive deviation below glideslope waring “GLIDESLOPE”
-Used for approaches with glideslope out of service, or LDA/LOC approaches
Recall the function of the APU BLEED pb
ON - Commands the APU bleed valve OPEN
Recall the function of the APU GEN pb
Light Out - APU generator will automatically energize once APU is on speed
OFF - APU generator is de-energized
Why must the aircraft batteries be on for all APU starts AND when the APU generator is the SOLE source of electrical power.
Turning the batteries ON permits the APU starter motor to connect to the battery busses, which are the sole source of power for the APU starter motor.
On the ground, in the event of an APU fire while the APU generator is the sole source of power, the batteries being on ensure a power source for proper APU shutdown and extinguisher discharge.
Recall the Emergency Equipment stored on the flight deck
4 crew life vests (orange)
1 Halon Extinguisher
1 Crash Ax
4 Crew Oxygen masks
2 escape ropes
1 Protective Breathing Equipment (PBE)

- AC BUS 2 automatically, via auto switching logic (AC BUS 1 fails)
Describe ignitor behavior during manual starts
Both ignitors (AB) are activated ONLY AFTE the Engine Master Switch has been selected ON.
What is Pitch Protection? When is it available?
ELACs will allow no greater than 30deg nose up/15deg nose down, regardless of side stick input.
ONLY AVAILABLE in NORMAL LAW
High Speed Protection
Attempts to prevent aircraft from exceeding VMO/MMO
ELACs automatically pitch up to limit further acceleration
- even if sidestick is held full forward
ONLY AVAILABLE in NORMAL LAW
Maneuver Protection
Think G’s!
Restricts flight control surface movement that would cause the aircraft to exceed its designed structural limits.
Clean Config : -1.0g to +2.5g
Slats Extended, Flaps retracted : -1.0g to +2.5g
Slats and Flaps Extended : 0.0g to +2.0g
Alpha Protection (Alpha Prot)
- Flight Control computers prevent the aircraft’s AOA from exceeding a predetermined threshold at low airspeeds.
- AP disconnects, spoilers retract
- Sidestick changes to direct pitch control
- Pilot inputs can override protection and further degrade AOA
ONLY AVAILABLE IN NORMAL LAW
Alpha Max
Alpha Max is the highest AOA that the flight control computers will allow.
CANNOT BE OVERIDDEN
ONLY AVAILALE IN NORMAL LAW
When are High and Low Speed Stabilities available?
Alternate Law
Alpha Prot PFD Indication

Maximum fuel imbalance between the wing tank inner cells.
Approx 3,300lbs.
Are Wing Tank fuel pumps equipped with automatic logic?
No. Pump operation is controlled by the respective pb and must ALWAYS be manually controlled.
When will the transfer valves automatically open? What is their purpose?
Both transfer valves automatically open when EITHER wing tank inner fuel cell level reaches approximately 1650lbs. They transfer fuel from wing OUTER tanks TO the wing INNER tanks.
With fuel in Center Tank, explain the normal (automatic) fuel feed priority
With flaps fully retracted…
- Center tank fuel is consumed first followed by wing tan fuel. ONLY the wing tanks pumps are equipped with pressure reducers. Reducers allow center tank pump pressure to preferentially supply the respective engine.
With flaps extended…
- Center tank pumps automatically shut off, per auto logic, allowing wing tank fuel to be consumed.
What is the function of the L & R TK PUMPS pbs?
Manually control their respective wing tank pumps.
ON (light out) - pumps runs continuously
OFF (white) - pump is deactivated and remains off
Effect of using the EMER CANC pb in response to ECAM WARNING
Warnings

- Extinguishers MASTER WARNING lights
- Does not affect the ECAM message display (MASTER MARNING message remains in view).
EMER CANC pb should only be used to suppress spurious MASTER CAUTIONS
Effect of using the EMER CANC pb in response to ECAM CAUTION
Cautions
- Extinguishes the MASTER CAUTION lights
- Cancels (stops) the aural warning (single chime) for as long as failure continues
- Cancels ECAM message display for the remainder of the flight (MASTER CAUTION message is removed)
- Canceled MASTER CAUTION messages can be recalled by pressing the RCL pb for 3 seconds.
EMER CANC pb should only be used to suppress spurious MASTER CAUTIONS
EMER CANC pb is NOT to be used in place of ECAM CLR pb when performing ECAM non-normal procedures.
