Question 1

CAT IIIb Operations

Answer 1

A precision approach operation with a DH lower than 50 ft, or no decision height,
and an RVR less than 175 m but not less than 50 m.

Question 2

Fail Operational Automatic Landing System

Answer 2

An automatic landing system is fail operational if, in the event of a failure below
alert height, the approach, flare and landing can be completed by the remaining
part of the automatic system.

Question 3

Fail Passive Automatic Landing System

Answer 3

An automatic landing system is fail passive if, in the event of a failure, there is not
significant deviation of aircraft trim, flight path or attitude but the landing will not
be completed automatically.

Question 4

Head Free

Answer 4

The Head Free pilot is responsible for calling external references as they
become visible and for making an assessment of the visual segment.

Question 5

Head Down

Answer 5

The Head Down pilot monitors instruments.

Question 6

Head Down

Answer 6

The Head Down pilot monitors instruments.

Question 7

ILS Critical Areas

Answer 7

Environmental changes including the presence of vehicles and aircraft will cause disturbances to the ILS signals, which will probably be unacceptable to an aircraft using the signals.

Question 8

ILS Critical Areas

Answer 8

Environmental changes including the presence of vehicles and aircraft will cause disturbances to the ILS signals, which will probably be unacceptable to an aircraft using the signals.

Question 9

ILS Sensitive Areas

Answer 9

parking and/or movement of vehicles and aircraft will affect the ILS signals and may be unacceptable to aircraft using the signals for automatic landing or rollout guidance.

Question 10

Low Visibility Operation (LVO)

Answer 10

An operation involving:
* a low visibility take-off (LVTO)
* an approach using minima less than the CAT I minima published in the AIP for the runway in use

Question 11

Low Visibility Takeoff (LVTO)

Answer 11

A take-off with an RVR or runway visibility (RV) lower than 550 m.

Question 12

Low Visibility Procedures

Answer 12

Procedures applied at an aerodrome for protecting aircraft operations during low visibility operations

Question 13

Mid–Runway Portion (MID)

Answer 13

The portion of a runway at approximately 1,000m to 1,500m from the threshold, near the mid portion of the runway.

Question 14

Runway Visibility (RV)

Answer 14

The distance along a runway over which a person can see and recognise a visibility marker or runway lights. It is assessed by an approved observer and reported by ATC.

Question 15

Runway Visual Range (RVR)

Answer 15

Runway Visual Range (RVR) is the range over which a pilot of an aircraft on the centreline of the runway can see the runway surface markings or the lights delineating the runway or identifying its centreline. RVR reporting must be available for all CAT II and CAT III operations.

Question 16

Special Authorisation Category I (SA CAT I) Operation:

Answer 16

A precision approach CAT I operation with a DH lower than 200 ft, but not lower than 150 ft; and an RVR not less than 450 m.

Question 17

Special Authorisation Category II (SA CAT II) Operation:

Answer 17

A precision approach operation to a runway where some or all of the elements of the precision approach CAT II lighting system are not available, and with:
* a DH lower than 200 ft, but not lower than 100 ft
* an RVR not less than 350 m.

Question 18

Standard IFR Takeoff Minima

Answer 18

The AIP specifies the following standard takeoff minima:
* a ceiling of zero feet; and
* visibility of:
(1) 550m - but only if the following conditions are complied with:
* the runway must have runway edge lighting at spacing intervals not exceeding 60m, and Runway centreline lighting (RCLL) or centreline markings (RCLM); and or less.
* if the aerodrome is a non-controlled aerodrome, or a controlled aerodrome without ATC in operation - the takeoff be conducted by day only, and the aerodrome must be one at which carriage of radio is mandatory; or
(2) 800m applies.

Question 19

Stop End or Rollout Portion (END)

Answer 19

The portion of a runway at approximately 300m from the runway end to the runway end. Selected to provide information relating to the latter part of the takeoff and landing runs.

Question 20

Stop End or Rollout Portion (END)

Answer 20

The portion of a runway at approximately 300m from the runway end to the runway end. Selected to provide information relating to the latter part of the takeoff and landing runs.

Question 21

Touchdown Zone (TDZ)

Answer 21

The portion of a runway, beyond the threshold, where it is intended landing aircraft first contact the runway.

Question 22

Touchdown Zone (TDZ)

Answer 22

The portion of a runway, beyond the threshold, where it is intended landing aircraft first contact the runway.

Question 23

Controlling RVR or RV

Answer 23

For any take-off or approach operation, a report from a particular RVR or RV reporting location is always controlling, whether or not the particular operation identifies that report as required.
