  1. What component of the ILS provides lateral guidance to the runway centerline?

    Answer: Localizer transmitter

    The localizer transmitter provides lateral (left/right) guidance aligned with the extended runway centerline.

  2. DME slant range distance differs from actual ground distance most significantly when an aircraft is:

    Answer: At high altitude and close to the DME station

    Slant range error is greatest when the aircraft is at high altitude close to the station because the slant angle is steepest.

  3. A VOR service volume classification of 'High' (H) provides reliable reception up to what altitude and distance?

    Answer: 14,500 ft to 130 NM and 18,000 ft to 100 NM

    A High VOR is usable from 14,500 ft AGL to 130 NM and from 18,000 to 45,000 ft at 100 NM.

  4. What is the standard ILS glide slope angle for instrument approach procedures in the United States?

    Answer: 3.0 degrees

    The standard ILS glide slope angle is 3.0 degrees, providing a safe and stable descent path to the runway.

  5. During a radar approach, if the controller loses radar contact, the controller must:

    Answer: Issue missed approach instructions and advise pilot of loss of radar contact

    When radar contact is lost during a radar approach, the controller must issue missed approach instructions and inform the pilot that radar contact has been lost.

  6. The outer marker of a standard ILS system is typically located at approximately what distance from the runway threshold?

    Answer: 4–7 NM

    The outer marker is typically located 4 to 7 NM from the threshold, marking the point where the aircraft should intercept the glide slope.

  7. RNAV (GPS) approaches use which navigation specification to ensure required navigation performance?

    Answer: LPV approaches use WAAS and provide precision-like lateral and vertical guidance

    LPV (Localizer Performance with Vertical Guidance) uses WAAS augmentation to provide precision-like lateral and vertical guidance down to 200 ft DH.
