Profile Knowledge Flashcards
How do you perform a Glideslope capture from ABOVE?
The following procedure should only be applied when established on the localizer. The flight crew must react without delay to meet the stabilization criteria.
In order to get the best rate of descent when cleared by ATC and below the limiting speeds, the flight crew should lower the landing gear and select flaps as required (at least CONF 2 should be selected to ensure that the aircraft speed will not increase).
IF ABOVE THE GLIDESLOPE (AFTER LOC* and LOC alive):
APPR mode ARM/CHECK ARMED
Ensure the APPR p/b is pressed, or is still illuminated if it has been selected previously and ensure that G/S BLUE is annunciated on the FMA.
FCU ALTITUDE SET ABOVE A/C ALTITUDE
If the pilot does not set the altitude above present altitude, it is likely the a/c will capture altitude (and level out) before intercepting the G/S.
As soon as possible select the Go Around Altitude.
V/S MODE SELECT
Select V/S 1500 ft/min initially. V/S in excess of 2000 ft/min will result in the speed increasing towards VFE.
Note:
When reaching VFE, the AP maintains VFE and reduces the V/S without MODE REVERSION.
How do we perform a Discontinued Approach?
If at or above the FCU altitude:
Announce “CANCEL APPROACH”.
To disarm any AP/FD approach mode, press APPR pb or LOC pb.
Note:
Valid only for ILS or FINAL APP guidance.
Select lateral mode as required (NAV or HDG mode).
Select vertical mode as required (level off or adjust V/S).
Select SPEED and adjust.
