Flight Management Flashcards
MMR
Uses 1 ILS and 1 GPS to integrate a single unit
Manual tuning a nav radio
MCDU on nav page either enter the identifier or frequency (M on the associated ND and large font on the MCDU. Auto tune disabled
RMP by selecting the guarded NAV button. R is displayed on the ND next to the frequency indicating RMP tuning. Auto tune disabled
ADIRU power sources
When selected to NAV it is connected to hot battery bus to test the system backup source for 5 seconds.
Normal power
ADIRU 1 AC ESS
ADIRU 2&3 AC BUS 2&1
If the emergency generator is online ADIRU 1 operates normally from the AC ESS bus
If after 5 minutes with no AC power ADIRU 2&3 are disconnected for the remainder of the flight
Full alignment required
First flight of the day
Questionable nav reception (class 2 airspace)
If prompted by special pages in the airway manual
Take off managed speed
SRS (speed reference system)
SRS equals V2 +10 for both engines and V2 for single engine
FMS Decent phase
Starts 200nm from destination or TOD point
Mix IRS position
Uses all 3 IRS’s for a blended position.
If an IRS fails a mix is not used
Radio position
Used when gps is inoperative
(Vor radial dme arc)
Take off update
On aircraft with no GPS IRS input is used while on the ground.
Runway bias is the difference between IRS MIX and the runway position. Prior to t/o the runway is entered in the active flight plan in the FMS
Then when take off power is set the FMGC position is automatically updated
Can see the update on the ND when the airplane symbol moves onto the runway
Take off shift
On aircraft operating without a gps and using an intersection departure runway.
Enter the feet on the TAKE OFF page in MCDU under TO SHIFT
EPE
Estimated position error
Is a radius around the computed aircraft position with 95% probability of accurate position data. Computed or dependent on type, frequency, and quality of the position updates.
Compared to the RNP
MCDU display colors
White: active waypoint, titles and labels
Cyan: don’t that can be modified. Tuned nav aids
Amber: mandatory data is missing. Entered constraint will be missed
Green: large font indicates pilot entered waypoints and other non-modifiable data. Small font shows computed data associated with the data line
Magenta: constraints and max altitude. Also signifies that the constraint will be met
Yellow: working with temporary flight data
Data entry to FMS
Yellow boxes: data required
Blue bracket: data entry is optional
Specific order entry: precede with a / if the data is preceded with a /
Weather radar fault notification
On ND not on ECAM
Radar stability
IRU 1
Tilt setting 0 doesn’t reflect the aircraft’s horizontal axis. Rather it represents IRU 1’s definition of the horizon
