Answer 20

DA is referenced to mean sea level (MSL) for precision approaches.

Question 21

How is the ‘procedure identification’ on an approach plate structured?

Answer 21

Question 22

What is the ‘marginalia’ in an approach plate?

Answer 22

The section that includes tower controller elements identification numbers and relevant procedural reference.

Question 23

How are different ILS categories defined?

Answer 23

ILS categories are defined based on operational minima with CAT I allowing operations down to a minimum of 200 ft DH at 2600 ft RVR and CAT II and III having even lower DH and RVR requirements.

Question 24

What is an ILS?

Answer 24

ILS stands for Instrument Landing System.

Question 25

What is the typical angular width for LOC adjustments?

Answer 25

The LOC is adjusted to provide an angular width typically between 3 and 6 degrees depending on runway length.

Question 26

Where is the transmitter antenna array located with respect to the runway?

Answer 26

The transmitter antenna array is located at the far end of the runway away from the approach.

Question 27

What does CAP provide in terms of localizer data?

Answer 27

CAP provides an estimation of the range of the localizer data displayed like this EO 303.2.

Question 28

What frequency range does a glide path transmitter operate within?

Answer 28

The glide path transmitter operates within the frequency range of 329.3 to 335 MHz.

Question 29

How is the glide path frequency paired?

Answer 29

The frequency is paired with the associated LOC frequency in accordance with ICAO standards.

Question 30

What is the typical approach angle for a glide path?

Answer 30

The glide path is adjusted to a published approach angle typically 3 degrees.

Question 31

What is the beam width for the glide path?

Answer 31

The beam width of the glide path is 1.4 degrees.

Question 32

How far is the glide path antenna array located from the approach end of the runway?

Answer 32

The antenna array is located approximately 1000 ft from the approach end of the runway and offset approximately 400 ft from the runway centerline.

Question 33

What can negatively affect the beam-forming area in front of the glide path antenna?

Answer 33

Heavy snow buildup can negatively affect the beam-forming area in front of the glide path antenna.

Question 34

What measures do airports take for heavy snow buildup near the glide path?

Answer 34

Airports have snow-clearing plans in effect for this area as the snow must remain below the allowable design depth for proper glide path operation.

Question 35

What happens if there is excess snow in the vicinity of the glide path?

Answer 35

If there is excess snow in the vicinity of the glide path the glide path may not issue reliable signals and must be shut down.

Answer 39

Some ILS may also have an associated DME.
