Approaches Flashcards
What are the required conditions for LNAV/VNAV, Fully Managaed ?
(3)
- Approach is defined in the Data Base.
- Approach has been crossed checked by the crew with the published procedures.
- Final approach has not been modified.
NPA Flying Reference:
Fully Managed ?
VNAV/SEL ?
Fully Selected ?
FINAL APP
LOC FPA, NAV FPA
TRK FPA
How should the flight crew proceed on a Fully Managed Approach should (NAV ACCY DNGRADED) or (GPS PRIMARY LOST) message is displayed.
VOR,ADF,VOR DME:
Cross check the NAV accuracy: if positive, continue the Appraoach.
If Negative, revert to selected approach with raw Data.
GPS approach:
Interrupt the approach if external visual reference are not sufficient.
Fully managed, steps on Approach: actions and reactions ?
Press (APPR) p/b on FCU,
1. On FMA - [APP NAV] becomes active, [FINAL] becomes, (ARMED).
2. VDEV or “BRICK” scale becomes active and will only be displayed
If LS pb is not pressed. If pressed the VDEV will flash in Amber.
3. ND should display a BLUE Arrow where the FMS predicts Engagement of the FINAL APP. (White arrow indicates at least one condition not met)
Conditions:
1. DECEL must be sequenced and FMS approach phase active.
2. APP NAV Engaged and [FINAL] ARMED
3. FMS must provide Predictions.
Diff between Vias and Trans on app and Dep ?
Trans are the transition point between the last fix of the Sid connecting to Enroute and on the App the last Enroute fix connecting to the Star and a Via is the point that connects the star to the final app.
What is a APV?
Approach Procedure with Vertical Guidance. It does not meet the requirements established for a precision approach
Autoland has been demonstrated under the following Limitations ?
Cat 2/3 ILS beam slope angle - 2.5 to 3.25
airport elevation 9,200 feet
Landing weight 229 tons
When would you use a “Stabilized” approach ?
- NPA VNav/SEL
- G/S greater than 3.5 degrees
- Tailwind
Where do you find the Required Validity requirements
