ESIS SFD Flashcards
Where is the ESIS SFD ADC located?
Nose compartment (ADC 4000)
What causes the VMO bar to be displayed on the SFD?
Anytime 170 KCAS is displayed on the airspeed tape
(Max Operational Speed)
tied to Vne of aircraft
Under what circumstances is there a need to initiate a FAST ERECT action from the menu list on the SFD?
Extended maneuver error;
DG indication continues-loss of magnetometer heading source
What is the maximum that pitch trim can be adjusted on the SFDs?
7 degrees
What are the components that make up the ESIS system for the SFDs
x2 Detachable Config Modules, x2 SFD, the ADC-4000, and a Magnetometer
What are the four selectable menu items on the SFD?
-fast erect
- set pitch trim
- set brightness
-Baro Type
A loss of heading information on the SFD indicates a possible failure of the?
Magnetometer
Where does the ESIS system receive electrical power from?
No. 1 Essential DC BUS for SFD 1
No. 2 Essential DC Bus for SFD 2
Define ESIS
Electronic Standby Instrument System
What information does the magnetometer provide to the SFDs?
Computes magnetic heading with pitch and roll data
Where is the magnetometer located?
AFT Pylon
A failure indication on the sides of the SFD indicate a failure of what ESIS component?
ADC-4000
What conditions must the aircraft be in to perform a Fast Erect on the SFD?
On the ground or straight and level non accelerated flight
What type of information does the ADC-4000 provide to the SFDs?
-Airspeed
- vertical speed
- altitude
DCM
Detachable Configuration Module (DCM-3000)
How long is SFD blank when going through power-on self test
15 seconds

Error Code
Error Message
What constitutes an extended maneuver
maneuver exceeding 6 minutes at a roll angle > 7° from level
What indicates a failure on the SFC
Red X’s
What indicates Attitude Failurex
“ATT FAIL”
How is power reset to the SFD
pulling circuit breaker
When is the DG (Directional Gyro) displayed within the SFD’s display area
With a temporary loss of magnetometer heading source
What type of failure stops the start-up process
System Failures
What does the ADC provide to the SFD’s
Airspeed, Vertical Speed, Altitude Data
What is the corrective action if “WARNING Power Reset Needed” appears on the SFD display
Bring aircraft to straight and level non-accelerating flight and then reset/recycle power to GH-3001
When does the menu listing automatically terminate with no mode activity on the SFD’s
15-20 seconds
