A320 Navigation And Radar Flashcards
FATHAG
What do the IR’s do
Flight path vector
AC position
Track
Heading
Attitude
Acceleration
Ground speed
BOATS
What do the ADR’s do?
Barometric altitude
OAS
Angle of attack
Temperature
Speed
How to fast align the IR’s
Turn to off for less than 5 seconds and back to nav. Takes about 3 seconds to align.
How to normally align the IR’s
Switching the IRU mode selector to OFF for more than 5 seconds and then back to NAV
What does the ON BAT light mean on the ADIRS?
When must a complete alignment be accomplished?
Before first flight of the day
Following a crew change
When GPS is not available and NAVAID coverage is poor on the expected route
When GPS is not available and expected flight time exceeds 3 hours
All international and Alaska flights
Flight in class 2 airspace
What does the FMGS do to reduce the pilots workload?
The flight management and guidance system provides:
Present position
Lateral and vertical navigation
Flight predictions
Navigation auto tune
What inputs does the FMGS need in order to navigate?
-2 flight management and guidance computers
-1 Air data inertial reference system (ADIRS)
-2 radio altimeters
-1 marker beacon receiver
-DME, VOR, and ILS receivers (One ILS receiver is combined with one GPS receiver to from a Multi-Mode receiver (MMR), there are 2 MMR’s on the aircraft)
-Global positioning system
How many VOR, DME, and ILS receivers does the A320 have?
2 of each
How many ADF’s do our A320’s have?
None of our NEO aircraft have an ADF receiver. And only of few of our CEO’s have 1.
How many frequencies does each of our DME receivers have?
5 frequencies. 3 for radio position updating, 1 VOR/DME display, 1 Localizer DME display.
How can you see VOR navigation information?
By selecting the ROSE knob to VOR. That will pop up a digital HSI on your ND.
What’s a Multi-Mode Receiver?
An MMR is a combined ILS and GPS receiver.
What are the 3 ways to tune radio nav receivers?
Auto tuning via the FMGS
Manual tuning via the MCDU RAD NAV page
Manual tuning by using the STBY NAV function on the RADIO MANAGEMENT PANEL’s (RMP’s)
What 4 things does FMGS auto tuning provide?
Localizer guidance during takeoff
FMS position updating
En route VOR/DME display
Approach guidance
What does pressing the guarded NAV button on the RMP do?
It enable standby tuning of radio nav frequencies and in doing so disables autotuning.
What are the components of the Air Data Inertial Reference System (ADIRS)?
It’s composed of 3 ADIRU’s or Air Data Inertial Reference Units. Each ADIRU is separated into AIR DATA Reference information (ADR) and Inertial Reference information (IR).
Which ADIRU provide captain side info? FO side?
ADIRU 1 provides captain side data. 2 provides FO side data. 3 is standby.
