A320 Fmgs-mcdu Little Secrets
I was wondering if any one has any little nice stuff to apply on the MCDU to share on this page for all A320 pilots and fans, I will start myself by posting the following:
From airbusdriver.net By captain anonymous
AT FL350 AND > 200 NM from destination (FLT PLN PAGE), ATC clearance: CROSS LRP AT FL 280.
1). Constraint entered on right side of FLT PLAN page (Vertical Constaints) as: “/280”
2). FCU Altitude set at FL 280 – DESCENT ENGAGE
A/C enters a “CRUISE DESCENT” to FL 280 and WILL NOT HONOR constraint entered at LRP
Indications are:
1). White message in MCDU Scratchpad – CONSTRAINT DELETED ABOVE CRUISE FLIGHT LEVEL: FL
2). CLR the Scratchpad – MESSAGE : NEW CRUISE ALT - FL280
3). FMA Indications: DES
4). PFD Indications - magenta “Target Airspeed” (Cruise Speed)
No magenta Profile Deviation Indicator (Doughnut)
5). MCDU Indications – PERF Page – Title “CRZ’ in green (Active Phase)
PROG PAGE – Title “CRZ” in green (Active Phase)
CRZ ALT – FL280 and NO Vertical Deviation Information
6). Notice where level-off arrow (blue hockey stick) is in relation to waypoint with constraint given by ATC
7). If level-off is past waypoint then you must “V/S” or “OPEN DESCENT – SELECT” in order to comply with clearance
If clearance received just prior to crossing 200 NM point, once inside of 200 NM a Managed Descent can be re-established by:
1). On PROG page enter an altitude in the CRZ field that is “ABOVE” you (example: FL370)
2). Watch FMA to change from “DES” to present “V/S”
3). Now re-enter constraint on FLT PLN page (LRP @ /FL280)
4). Re-engage “DES” (Managed Descent)
5). FMA indications: “DES”
6). PFD indications:
Managed Speed “window" indicating SPEED
Vertical Deviation Information (magenta doughnut)
7). MCDU Indications:
PERF Page – “DES” in green (Active Phase)
PROG Page – “DES” in green (Active Phase)
No Cruise Altitude in CRZ FL
Vertical Deviation Indication (Example: -1580’)
8). Look for Profile Capture Point (blue lightning bolt ) on NAV Display and blue Level-Off Point at or prior to waypoint
