Flight Data, Navigation And Instruments Flashcards
From where do the ADC’s get pitot/ static information
The air data system consists of three pitot• static systems, two Air Data Computers (ADC), two angle-of-attack vanes, and two temperature probes. Pressure information to various instruments and systems is provided directly from the pitot-static system, or indi• rectly via the air data computer.
What do the ADC’s feed information to
Three independent pitot-static systems pro• vide pitot and static pressure to various instruments and systems, and to the air data computers.
What happens when an ADC fails ? What can you do about it
In the event of a failure, an alert will be pre• sented and the offside ADC can be selected with the ADC source select p/b at the main instrument panel. Selection of the offside ADC is indicated at the onside source select and altimeter set panels
Where do you set the QNH reference pressure
The QNH reference pressure can be set at the altimeter set panel.
What feeds the standby altimeter and standby ASI
System 3 Standby ALT (static only) Pitot static system standby ASI
What does the angle of attack vanes provide information for
Two vane-type angle-of-attack sensors, 1 and 2, located left and right of the forward fuselage, provide angle-of-attack informa- tion to the respective air data computer, AFCAS, and stall prevention system.
Where does the TAS information to the IRS’s come from
ADC
From where can you enter data into the IRS’s
IDSU and FMS
If an IRS Fails , what do you see and what can you do.
Alert is represented, IRS FAULT, ATT AND HDG FLAGS ON PFD
How and from where can you align the IRS’s
Align and Nav
How long does the alignment take
10 minutes
Can the aircraft be moved during alignment
No
What mode will the IRS’s be in after alignment
NAV
How could you realign the IRS
Align or Nav
Where can the weather radar be displayed
On the ND in map or arc mode
Can the pilot display be individually controlled
Yes
What so dashes in the VOR/DME mean
VOR/DME tuned Automatically
What can you do if an ILS fails
In the event of a failure an alert will be presented and the offside ILS can be selected with the ILS source select p/b at the main instrument panel
In the event of a failure an alert will be presented and ILS 3 can be selected with the ILS source select p/b at the main instrument panel
When is ILS frequency tuning inhibited
Frequency tuning is inhibited when the LAND mode is engaged.
What can you do when an RA fails
In the event of a failure, an alert will be presented and the offside radio altimeter, or system 3 radio altimeter where fitted, can be selected with the RA Source Select P/B at the main instrument panel
What do the EFIS displays consist of
PFD, ND
How many EFIS Control panels are there
Two
What can you do in case of display unit failure
A PFD/ND transfer push button is provided in case of unit failure
Where are pitch, roll and heading compared
On the PFD, FWC
Where is the attitude normally displayed
On each PFD and standby AH
Where is ILS information displayed
PFD as well as ND
Where is heading and course normally displayed
ND
What can be displayed on the RMI
VOR AND DME OR ADF AND DME
When is the standby horizon powered
When battery is on or when either eng is running
How is avionics cooling accomplished
Avionics compartment, main instrument panel, glare shield, and pedestal are cooled by the avionics cooling system. The system consists of three blower fans, two suction fans, and an emergency cooling fan. Cabin air is ducted to the system by the blower fans. The spent air is drawn from the system by the suction fans and is dumped in the area aft of the forward cargo compartment.
