Flight Insts/warnings Flashcards
What Flight Information is displayed by the ISFD ?
Attitude Airspeed Altitude ILS GLS and heading information
When does the EGT start limit line appear on EGT indications?
When Engine Fire Switch is in
Fuel Switch - cut off
N2 RPM below Idle
What causes the Automatic Display of Secondary Engine indications ?
- When displays first receive electrical power
- Fuel Control is moved to Cut Off in flight
- An Engine Fire Switch is pulled in Flight
- A Secondary engine parameter is exceeded
- Engine N2 RPM is below idle in flight
- A Start Selector is in the START position
- FUEL FLOW ENG L/R Advisory is shown.
When AIR DATA / ATT Source selector is in Auto what is the PRIMARY source ?
ADRS
When AIR DATA / ATT Source selector is in Auto what is the Source of the backup information
AIRSPEED
ALTITUDE
ATTITUDE ..?
1 Angle of Attack and INERTIAL DATA
2 GPS
3 ISFD
Display CURSOR Control is provided by which units? (3)
CCD. MFK . EFIS CTRL
What are the Primary source of attitude and inertial navigation system information to the flight displays ?
The IRS is the primary source for attitude and inertial navigation position information. The major components of the IRS are:
two inertial reference units (IRU)
two attitude heading reference units (AHRU)
The IRUs use what Data to compute position information ?
The IRU is the primary source for independent inertial navigation position information. The IRU processes information measured by its internal gyros and accelerometers and GPS inputs. (Refer to Inertial Reference Unit (IRU) in Chapter 11., Section 20, for additional information.)
What are the major components of the ADRS ?
The ADRS provides primary, secondary, and standby air data. The major components of the ADRS are:
six air data modules six static ports three pitot probes two angle-of-attack sensors one total air temperature probe.
What are the main components of the IRS?
2 IRUs
2 AHRUs
What is the sequence of page selections for the FMC ?
- IDENT
- POS REF
- RTE
- DEPARTURES
- NAV RAD
- PERF INIT
- THRUST LIM
- TAKE OFF REF P1/2
On what page can the Flight Crew check accuracy of the three FMC positions ?
Position Reference Page 3/4
On position reference page 3, the flight crew can observe the calculated positions of the left, right and center FMCs. The line title indicates which FMC is being used as MASTER, SPARE or BACKUP. This page also allows the flight crew to enable or inhibit position updating modes used by the FMC.
What info is displayed on POS REF 4/4 ?
Position Reference Page 4/4
Position reference page 4 displays the present position of individual navigation sensors in bearing/distance format from the Master FMC position. This page provides the capability to remove specific sensors from the FMC navigation solution.
What type of Alert messages can be shown on the EICAS
Warnings Cautions Advisory Communications Status Memo
EICAS MESSAGES - how can they be differentiated ?
RED - Warning / Aural CAUTION - Amber / Aural ADVISORY - Amber indented Memo / status - White Comms - White low indented
