Flight Data, Navigation And Instruments

Question 1

From where do the ADC’s get pitot/ static information

Answer 1

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.​

Question 2

What do the ADC’s feed information to

Answer 2

Three ​ independent​ ​ pitot-static ​ systems​ ​ pro• ​vide​ ​ pitot​ ​ and​ ​ static ​ pressure​ ​ to ​ various​ ​instruments and​ systems,​ ​ and​ to the​ air data ​computers.​ ​

Question 3

What happens when an ADC fails ? What can you do about it

Answer 3

In the​ event​ of​ a ​fa​ilu​r​e​,​​ 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

Question 4

Where do you set the QNH reference pressure

Answer 4

The ​ QNH​ ​ reference ​ pressure ​can ​ be​ ​ set​ ​ at​ ​ the​ ​ altimeter​ ​ set ​ panel.

Question 5

What feeds the standby altimeter and standby ASI

Answer 5

System 3 
Standby ALT (static only)
Pitot static system standby ASI

Question 6

What does the angle of attack vanes provide information for

Answer 6

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.

Question 18

What can you do if an ILS fails

Answer 18

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

Question 19

When is ILS frequency tuning inhibited

Answer 19

Frequency​ tuning​ is ​inhibited​ when​ the​ LAND mode​ is engaged.

Question 20

What can you do when an RA fails

Answer 20

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

Question 30

How is avionics cooling accomplished

Answer 30

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.
