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 The link is here |
