INSTRUMENT LANDING SYSTEM (ILS) Flashcards
1
Q
- The coverage of an ILS localiser extends to …………… either side of the on course line out to a range of …………… nm.
A
35°, 17
2
Q
- The upper and lower limits of an ILS glide path transmitter having a 3.5° glide slope are:
A
6.125° - 1.575°
3
Q
- The minimum angle at which a false glide path is likely to be encountered on a 3°glidepath is:
A
6 degrees
4
Q
- The visual and aural indications obtained when overflying an ILS middle marker are:
A
alternating medium pitch dots and dashes with amber light
5
Q
- An aircraft carrying out an ILS approach is receiving stronger 150 Hz signals than 90 Hz signals. The correct actions to be taken to place the aircraft on the centreline and on the glidepath are to fly:
A
UP and LEFT
6
Q
- In elevation the upper and lower limits of an ILS glide path transmitter having a 3.0 degree glide slope are:
A
5.25° & 1.35°
7
Q
- An aircraft tracking to intercept the ILS localiser inbound on the approach side but outside the published coverage angle:
A
will receive false on-course or reverse sense signals
8
Q
- The outer marker of an ILS installation has a visual identification of:
A
continuous dashes at a rate of 2 per second, blue light
9
Q
- The specified maximum safe fly up indication on a 5 dot CDI is:
A
2.5 dots fly up
10
Q
- An aircraft is attempting to use an ILS approach outside the coverage sectors of an ICAO standard system:
A
from the localiser needle the captain may be receiving false course and reverse sense indications and from the glideslope needle intermittent and incorrect indications
11
Q
- The coverage of the ILS glideslope in azimuth is:
A
± 8° out to 10nm
12
Q
- An aircraft’s Instrument Landing System glideslope and localiser receivers are receiving predominant 90Hz modulated signals. If the aircraft is within the coverage of the ILS, QDM of 264°, it is:
A
south of the localiser and above the glideslope
