|
What are the three components of an ILS system
|
Localizer - Provides course guidance to the runway centerlineGlideslope - provides vertical guidance to maintain proper approach angleMarker Beacons - provide indications of progress along the approach path
|
|
How does the DME system work
|
Aircraft sends paired signal pulses (962-1213 MHz)Recieved by ground station and retransmitted to the aircraftAircraft DME measures time for round tripAircraft DME calculates SLANT DISTANCE (not horizontal distance)
|
|
What are the 3 components of the T-6 Flight Instruments
|
Electronic Flight Instrument System (EFIS) - EADI & EHSIAir Data System - Altimeter, Airspeed Indicator, VSIStandy Instruments - Airspeed Indicator, ADI, Altimeter, Turn and Slip indicator, Magnetic Compass
|
|
What are the two components of the EFIS
|
Control Panel5 inch Electronic Attitude Director Indicator (EADI)5 inch Electronic Horizontal Situation Indicator - EHSI
|
|
In composite mode what happens
|
Both Attitude and heading information can be displayed on either the EADI or EHSI
|
|
Where do the EADI and EHSI reciever their information
|
Attitude Heading and Reference System (AHRS)
|
|
What is the AHRS
|
All attitude inertial sensor system that provides:Aircraft AttitudeHeadingFlight dynamics informationto the aircraft systems and displays
|
|
Is the AHRS system automatic
|
Yes, fully automatic does not NORMALLY need interaction from the pilot
|
|
Where is the controller for the AHRS system
|
Lower-right side of the front cockpit instrument panel(2 switches mode control, and slew control)
|
|
What position should the AHRS mode control switch normally be left in
|
SLVD (pronounced slaved)
|
|
What does the meter next to the AHRS mode control switch indicate
|
Slave error indicationsHorizontal line = no errorAt an angle = slave error
|
|
What happens when the AHRS mode control is turned to the DG (directional gyro) position
|
EHSI becomes a compass card with inaccurate heading information
