After tuning the correct ILS frquency, and receiving the correct ident, the pilot notice that the Localiser (LOC) and Glide Path (GP) indicators are both showing warning flags. The pilot confirms that the aircraft is within the prescribed coverage area of the ILS. What is the most probable reason for the warning flags showing?

More than full scale deflections are indicated.

The aircraft fails to receive any modulating signals (90 Hz and 150 Hz).

Another aircraft ahead, on the same ILS approach, is disturbing the transmission.

An incorrect course is selected on the OBI or HSI.

A pilot has selected the appropriate ILS frequency for the approach that they are currently established on. Which of the following scenarios would cause a warning flag to appear on both the Localiser (LOC) and Glide Path (GP) indications?

Excessive LOC and GP deviations.

Absence of both carrier waves.

A difference in depth of modulation of zero.

Loss of ILS ident transmission.

Every 10 kt decrease in groundspeed on a 3° ILS glide path will require...

an increase in the aircraft's rate of descent of approximately 100 ft/min.

a decrease in the aircraft's rate of descent of approximately 50 ft/min.

an increase in the aircraft's rate of descent of approximately 50 ft/min.

a decrease in the aircraft's rate of descent of approximately 100 ft/min.

Which failure in radio navigation is connected with "Fading"?

Twilight/night Effect

Static Discharge

Shoreline/coastal Effect

A crew is briefing for a procedural VOR approach that requires a procedure turn for their destination airport, which involves a 80 turn to the left. This procedure turn consists of a straight track with track guidance on the 098 radial from a VOR, followed by a turn of left to a heading of 018 , followed by a:

Timed straight leg without track guidance and a 180 turn to the right to intercept the inbound track.

260 turn to the right to intercept the inbound track.

Timed straight leg without track guidance and a 180 turn to the left to intercept the inbound track.

Timed turn to the left to intercept the inbound track.

Which information should be provided by a single direction-finding station on request from an aircraft that is within range of the direction-finding system?

The magnetic bearing of the aircraft from the station, magnetic heading to the station, aircraft position in

relation to the station, and distance from the station.

The true bearing of the aircraft from the station, magnetic bearing of the aircraft from the station, true

heading (in no wind) to the station, and magnetic heading (in no wind) to the station.

The true bearing of the aircraft from the station, true heading (in no wind) to the station, aircraft position in

relation to the station, and distance from the station.

The true bearing of the aircraft from the station, magnetic bearing of the aircraft from the station, true heading

to the station (with a wind correction angle applied), and magnetic heading (with a wind correction angle

applied) to the station.

A CAT ILS with a decision height of 240 ft is what type of approach?

Type B, 3D approach

Type A, 2D approach

Type A, 3D approach

Type B, 2D approach

Why do VHF radio signals used for communication and navigation have a limited range?

Direct waves interfere with ionosphere waves.

Sky waves are refracted from the D-layer.

Because of the curvature of the Earth.

Ground waves are absorbed by the Earth's surface.

When raising the frequency of an electromagnetic wave, the:

Wavelength decreases

Wavelength and amplitude increases

Wavelength remains the same
