True

20
Q

______ is equipment (airborne and ground) used to measure, in nautical miles, the slant range distance of an aircraft from the DME Navigational aid.

A

Distance Measuring Equipment (DME)

21

A

In the aircraft

23
Q

DME operates on what frequency?

A

UHF

24
Q

A

VHF mono directional range/tactical air navigation (VORTAC)

25
Q

What 3 individual services does a VORTAC provide at 1 site?

A

  • TACAN azimuth
  • TACAN distance (DME)
26
Q

The frequency channels of the VOR and the TACAN AT EACH _______ facility are paired to simplify airborne operation.

A

VORTAC

27
Q

DME distance is displayed ________.

A

As a slant range distance

28
Q

What DME equipment on the ground is required to respond to the aircraft interrogator?

A

29
Q

The ILS is designed to provide: (2)

A
  • approach path with both course and altitude guidance

- exact alignment and descent of an aircraft on final approach to a specific runway

30
Q

The directional transmitters for the ILS are what?

A

Localizer and glide slope transmitters

31
Q

Name the 4 parts of an ILS:

A
  • localizer: provides horizontal (lateral) guidance along the extended centerline of the runway
  • glide slope: provides vertical guidance along the descent path toward the runway touchdown point
  • marker beacons: range information along the approach path (distance to threshold info)
  • compass locator: low power, low or med frequency (l/mf) radio beacon installed at the site of the outer or middle marker
32
Q

T/F: Where a complete ILS system is installed on each end of a runway, the ILS systems are not in service simultaneously.

A

True

33
Q

The approach course of the localizer is called the ________.

A

Front course

34
Q

Where is the localizer signal transmitted from?

A

Departure end of the runway

35
Q

The localizer sends out how many radials?

A

1

36
Q

Ils approach is not usable if ______ is out of service.

A

Localizer

37
Q

Glide slope

A

Provides the pilot with vertical guidance to the runway in the direction of the localizer.

38
Q

Marker beacons

A

Identify particular locations on the approach to an instrument runway; 3watts or less and produce an elliptical pattern
