Section X - Flight Instruments, Displays Flashcards
At what airspeed will the Mach/Airspeed indicator (CFD) begin to display current indicated airspeed? At what speed will it display Mach?
30 knots / Mach .40
During climb, at what altitude will the Altimeter ALT light illuminate?
- 900 feet prior to the selected altitude.
- 300 feet prior will extinguish.
With respect to the standby instruments (CFD), what is the power source for the Standby Attitude Director Indicator (Standby ADI) in the event of a dual generator failure?
STANDBY DC BUS.
Where do the STANDBY Attitude Director Indicator get the ILS Information?
Provided by the C-ILS Receiver
With respect to the standby instruments (CFD), from which source does the Standby Airspeed Indicator receive information?
L AUX PITOT and ALTERNATE static ports.
What information is provided by the Integrated Standby Flight Display?
- Attitude (Internal inertial sensor)
- Airspeed
- Altitude
- ILS (center ILS receiver)
- Magnetic heading information (from the left IRS only).
With respect to the Instrument Source Panel what is accomplished when selecting the Captain’s Electronic Flight Instrument (EFI) Switch from Normal to Alternate?
The captain’s displays will now use:
- The Center symbol generator
- Center ILS receiver
- Center radio altimeter.
What is the primary purpose of the Inertial Reference System (IRS) Switch on the Instrument Source Panel?
It switches IRS as the source of information for:
- Left and Center Symbol Generators
- Captain’s VSI
- First Officer’s RDMI
What is accomplished by switching the IRS Switch from normal to alternate mode on the captain’s side?
It switches the CENTER IRS as the source of information
What is the primary purpose of the Air Data Switch on the Instrument Source Panel?
Selects the AIR DATA COMPUTER used as the source of information for:
1. The Mach/airspeed indicator
2. Primary altimeter
3. And vertical speed Indicator (via the selected IRS)
The Speed Trend Vector (green arrow) on the airspeed indicator indicates the predicted airspeed in _________ seconds based on current acceleration or deceleration? (ADV)
10 seconds
When does the Flight Data Recorder (FDR) turn on?
The recorder automatically turns on when either engine is operating or the airplane is in flight.
How many Air Data Computer’s are installed?
Two. L + R (powers left and right instruments respectively).
Where can a Total Air Temperature (TAT) information be found while in flight?
TAT appears on the primary EICAS display above the engine indications and is supplied by a thrust management or air data computer.
What are some examples of flight guidance lost that would require using the alternate switches ?
- FMC BASIC NAVIGATION
- EFI BLACK PANEL
- Air Data Alt.-Air speed- Vert. Speed.
- IRS Ball ( brick ) & Heading
- FLAGS AND X’s on screens
