Instruments Flashcards
Putting the PFD brightness to off will
Transfer the PFD to the ND
The ADIRU provides
Speed, altitude attitude and position information
Each DMC has a channel for __ and __
EFIS and ECAM
DMC 1, 2 and 3 usually provide
CA screens, FO screens and ECAM screens
How would you know there’s a DMC failure
A crossbar in the displays affected
On the ECAM, the E/WD always has
Priority
When the upper ECAM has failed, you can see an SD page temporarly by pressing and holding the system page, how long does it stay before the E/WD comes back
3 minutes
ADIRS is 1 system that replaces the
ADC and IRS
ADIRS is comprised of 3 ADIRU, a CDU and
Many inputs and outputs
What are the 2 parts of the ADIRU
ADR and IR
The ADIRS supplies data to
FMGEC, FADEC, PRIM, SEC, FWC, SFCC, ATC, GPWS, CMC and CPC
The ADIRS can only align in those lattitude
60S to 82N (73N between 90-120W)
What are the 4 types of sensors on the side of the A/C
Pitot, Static, AOA and TAT
How many ADM are on the A/C
8
How many static ports are installed
6
On the ADIRS control panel, putting the switch to ATT is normally done when
The NAV mode a failed
Once the ATT mode is selected, the NAV mode can’t be used until
An alignement on the ground
If a Fault light is flashing in an IR pb, it means that
The attitude and heading can be recovered by putting the switch to ATT, you lose position data
You can perform a fast realignement by
Putting all switch to off and back to NAV in less than 5 seconds
The baro can display
hPa or Hg
When the FCU is initialized, the baro shows
1013 or 29.92
When you pull the baro knob, what happens
Switch to standard pressure
The ILS button shows
The LOC/GS scale on the PFD
If the ND mode or range data fails, the default ND is
Rose NAV and 80 NM scale
The normally gray background turns black if
The instrument cooling problem is detected
On ground, what is the white box and ‘‘cross’’ on the PFD
It is the max sidestick deflection symbol, and the cross shows the position of the sidestick
On ground, what is the green vertical line
It is the Ground Roll Guidance Command Bar
When bank exceed 45 degrees, all PFD symbols get removed except
Airspeed, Altitude, Attitude, Heading and V/S
