Navigation System Flashcards
VOR stations transmit beams, called _____, in every direction. In the T-6A, these signals are detected by the VOR receiver and displayed on the ______.

False
Any aircraft within line of sight and equipped with a transponder set to the same code as either the ground station’s or airborne interrogation system’s query responds ______ with a coded signal to the system interrogating it
Automatically
When you are requested to “SQUAWK ALTITUDE,” you press the mode select switch on the right side of the field to change the mode from “ON” to what?
ALT
When requested to “IDENT,” press the “IDT” button on the RMU. The ident signal will transmit for how many seconds, before returning to the previous mode?
20 seconds
True or false: NACWS data is continually displayed on the engine/systems/NACWS display
False
A white unfilled rectangle symbol on the NACWS display indicates within plus or minus ______ feet of aircraft attitude
300
True or false: TAS traffic warnings and advisories are displayed on the AEDD in both cockpits
False
What are the TAS range selections?
3, 5, 10, 20, 40 NM
Proximity traffic is displayed as a filled white diamond indicating the intruding aircraft is within +- how many feet relative altitude?
1200
True or false: In Above mode, traffic from 9000 ft above to 2700 ft below the aircraft is displayed
False
True or false: The front cockpit GPS unit must be on and functioning for either the front or rear unit to be used
True
The information on the right side of the Self Test display of the GPS should usually be correct since it is stored in what kind of memory?
Battery-backed
True or false: If on the first GPS system self-test attempt, TEST FAIL replaces ANNUN ON on the Self Test display, you must notify maintenance
False
The large outer knobs on the left and right sides of the GPS panel are used to select ______ for the left and right sides of the screen respectively
Page types
To change an item on a displayed page, first press the CRSR button, then use the ______ knob to move the cursor to the field to be changed
Outer
To declutter a GPS display, which button would you push?
CLR
The GPS can store up to ____ flights plans in memory, each of which can contain up to ____ waypoints
25, 30
The DME system displays what from the aircraft to the ground station?
Slant range in nautical miles
When the GPS first activates, the screen will display the ____ page as the default page for the left side of the display, and the right side will display the waypoint page for the last active waypoint
NAV 2
The 360° radial of each VOR station is oriented to what?

Glideslope scale and indicator
On the NACWS display, an upward or downward triangle with no altitude tag denotes traffic where?
1000 to 2700 feet off altitude
To use DME from one navigation facility while on approach to another facility, what should you do before switching the primary navigation frequency to the approach facility?
Press the DMEH button on the RMU
To transmit a special pulse to aid in immediate identification on a controller’s scope, you press which button on the RMU?
IDT
True or false: An advantage of the GPS flight plan function is that desired routes can be created before flight
True
TAS detects and tracks other aircraft by interrogating their transponders and then analyzing the replies to determine range, bearing, and relative what?
Altitude
