Answer 4

1. Segment of at least 3 consecutive lights being:
   - The center light of the approach lights, or
   - Touchdown zone lights, or
   - Runway centre line lights, or
   - Runway edge lights, or
   - A combination of these, and
2. A lateral element of the ground pattern:
   - An approach lighting crossbar, or
   - The landing threshold, or

Answer 5

300 m

Question 6

A category III operation is a precision instrument approach and landing using ILS or MLS with the following minima:

Answer 6

1. Fail operational
   - DH 0-49 ft (OS states 0 ft) // RVR 75 m
2. Fail passive
   - DH 50-99 ft (OS states 50 ft) // RVR 200 m

Question 7

No pilot may continue a precision approach CAT III fail passive below the DH unless the following visual references is attained and can be maintained:

Answer 7

At least 3 consecutive lights being:
- The centerline of the approach lights, or
- The touchdown zone lights, or
- The runway center line lights, or
- The runway edge lights, or
- A combination of these is attained and can be maintained.

Question 8

No pilot may continue a precision approach CAT III fail operational with a DH below the DH unless the following visual references is attained and can be maintained:

Answer 8

At least one centerline light is attained and can be maintained.

Question 9

Visual requirements for CAT III fail operational with no DH:

Answer 9

Not required

Question 10

The controlling RVR

Answer 10

Touchdown zone RVR
If not available, then the MID RVR should be the controlling RVR.
MID and Stop end are advisory and should allow the pilot to determine if sufficient visual reference exist to control the aircraft during roll-out and taxi

LVO is defined as operations below which RVR?

Answer 11

550 m

Non-LVO RVR/VIS required for takeoff

Answer 13

1. 500 m (Day only)
2. 400 m (Note)
   Note: At least runway edge lights or runway centerline markings at day, or at least runway edge lights and runway end lights or runway centerline lights and runway end lights at night

Question 14

LVTO RVR 300 m, facilities required:

Answer 14

1. Day: Runway edge lights and runway center line markings
2. Night:
   - Runway edge lights and runway end lights, or
   - Runway center line lights and runway end lights

Question 15

LVTO RVR 150 m (TDZ, MID, Rollout), facilities required:

Answer 15

1. Centerline markings, and
2. Runway end lights, and
3. Runway edge lights, and
4. Runway center line lights

Question 16

LVTO RVR 125 m (TDZ, MID, Rollout), facilities required:

Answer 16

1. Centerline markings, and
2. Runway end lights, and
3. High intensity runway edge lights spaced 15 m or less, and
4. Height intensity runway center line lights spaced 60 m or less

Question 17

LVTO the reported RVR value representative of the initial part of the takeoff run can be replaced by pilot assessment. As follows:

Answer 17

90 m visual segment is available from the flight crew compartment. (7 center line lights at 15 m spacing once lined up on the runway)
