The middle marker beacon is modulated with an audio tone of:
In order to measure the radial from a VOR, the aircraft VOR receiver
The secondary or harmonic false glidepaths in an ILS antenna’s vertical radiation pattern result from:
An aircraft is flying a 3° glidepath and experiences a reduction in groundspeed from 150 kt at the outer marker to 120 kt over the threshold. The effect of this change in groundspeed on the aircraft's rate of descent will be a decrease of approximately:
Assuming the normal ICAO Annex 10 localiser front-course coverage, without an approved reduction and within its specified height and line-of-sight limits, which point lies within the required sector? Distances are measured from the localiser antenna.
According to ICAO Annex 10, in which frequency band(s) does a locator normally transmit?
In the EASA theoretical-knowledge objective on remaining within protected ILS approach airspace, which glidepath deflection limit is specified?
In FAA radar-surveillance terminology, the typical nominal range class of a long-range surveillance radar is approximately:
Assuming sufficient transmission power, the maximum range of a ground radar with a pulse repetition frequency of 450 pulses per second is: (Given: velocity of light is 300 000 km/s)
