Instruments Flashcards
During normal operations, which flight instrument receives information directly from the ADC?
Pilot’s altimeter by ADC#1 and co-pilot’s by ADC#2
What information does the #1 ADC receive?
Pitot, static, temperature, altimeter setting, encoding altitude, altitude selection, overspeed, HSI selection #1 Nav Data
What does the HSI SEL switch do?
Couples the HSI selected side and the ADC to the autopilot
What is the indication of an ADC failure?
A flag will appear on the affected altimeter.
What action should be taken if an ADC fails?
Switch HSI SEL to the other side
What are the standard operating modes for the AHRS?
Normal for Attitude, Slaved for heading
What are the reduced operating modes of the AHRS?
Basic for Attitude, DG for Heading
What is the BASIC mode of AHRS?
Attitude information not corrected for acceleration
What are the limitations for take-off in reduced operating mode of the AHRS?
Not Approved - Prohibited
What action should be taken in the event of an ATT failure?
Engage ATTITUDE REVERSION by pushing ATT REV on the EFIS Controller
What happens when you engage ATT REV on the EFIS Controller?
Attitude information is displayed on the EADI from the cross-side and the opposite side ATT1 or ATT2 is displayed on the reverted EADI
What action should be taken in the event of a HDG failure?
Engage Heading Reversion by pushing HDG REV on the EFIS controller
What happens when you engage HDG REV on the EFIS Controller
Heading information is displayed on the EHSI from the cross-side and the opposite side MAG1 or MAG2 is displayed on the reverted EHSI
Where does the standby altimeter receive static pressure from?
Pilot Static Source or Alternate Static Source (depending on MOD)
What does the alternate static selector do?
Provides an Alternate Static Source for either the Pilot or Co-pilot
What does the AOA F-S indicator on the left side of the EADI indicator?
Speed relative to the Vref speed
What are the indications of a radio altitude failure?
Dashes after the RA on the EADI and the Rising Runway is removed
Where is the digital RAD ALT information displayed?
Lower right corner of the EADI
What are the indication of a CRT failure?
Blank screen
What action should be taken following a CRT failure?
Turn the failed unit off and switch to the composite mode display
What limitations are there when using composite mode
No ILS permitted on the composite side
What is the indication of a symbol generator failure?
Blank screen on EADI and EHSI
What is the indication of a symbol generator data failure?
Large X across screen, SG FAIL screen
What action should be taken in the event of a symbol generator failure and what is the indication following the action?
Push REVN button above the EADI to get the opposite side information on the failed side, noted on left side of EADI
What are the marker indications displayed?
EADI under the vertical Glide Slope. On the annunciator panel above the EADI
Where is the DH set and displayed?
Set on the EFIS controller and displayed on the lower left side of the EADI
Where does the standby altimeter receive static pressure from?
Pilot or Alternated Static depending on MOD
How does the standby attitude indicator operate?
Electrically powered gyro
