approach ban

[fogghorn]

Likely this one has come up recently but need to ask again. 50% can be applied to the advisory vis but there are a number of restrictions - Any takers I know that there are op specs to meet and straight in etc. but seems to me there has to be centreline lighting which pretty well rules everyplace but yvr out.

[200hr Wonder]

CYXS has GREAT center line lighting now, the LEDs are friggin bright!

Biggest restriction is LVOP/RVOP.

I'll do my best to lay this out in a format that makes sense.

For 703/704, with the ops spec an aircraft can use the 50% of the CAP advisory vis to all approaches non precision. For a precision approach you require the centre line lighting plus other stuff to be able to use the 50%. If you don't have these items you are limited to 75% of the advisory vis, which is more often than not 1600 RVR and 3/8s mile.

Here are the CARS, very legally worded but you can sort it out in there. This is for 703.

703.41 (1) For the purposes of subsections (2) to (4), the visibility with respect to an aeroplane is less than the minimum visibility required for a non‑precision approach, an APV or a CAT I precision approach if, in respect of the advisory visibility specified in the Canada Air Pilot and set out in column I of an item in the table to this section,
(amended 2006/12/01; previous version)

(a) where the RVR is measured by RVR “A” and RVR “B”, the RVR measured by RVR “A” for the runway of intended approach is less than the visibility set out in column II of the item for the approach conducted;

(b) where the RVR is measured by only one of RVR “A” and RVR “B”, the RVR for the runway of intended approach is less than the visibility set out in column II of the item for the approach conducted;

(c) where no RVR for the runway of intended approach is available, the runway visibility is less than the visibility set out in column II of the item for the approach conducted; or

(d) where the aerodrome is located south of the 60th parallel of north latitude and no RVR or runway visibility for the runway of intended approach is available, the ground visibility at the aerodrome where the runway is located is less than the visibility set out in column II of the item for the approach conducted.

2) No person shall continue a non‑precision approach or an APV unless
(amended 2006/12/01; previous version)

(a) the air operator is authorized to do so in its air operator certificate;

(b) the aeroplane has a minimum flight crew composed of a pilot‑in‑command and a second‑in‑command;

(c) if the flight crew does not use pilot‑monitored‑approach procedures, the aeroplane is equipped with an autopilot capable of conducting a non‑precision approach or an APV to 400 feet AGL or lower;

(d) the instrument approach procedure is conducted to straight‑in minima; and

(e) a visibility report indicates that

(i) the visibility is equal to or greater than that set out in subsection (1),

(ii) the RVR is varying between distances less than and greater than the minimum RVR set out in subsection (1), or

(iii) the visibility is less than the minimum visibility set out in subsection (1) and, at the time the visibility report is received, the aeroplane has passed the FAF inbound or, where there is no FAF, the point where the final approach course is intercepted.

Nothing in there regarding centre line lighting for Non precision to use 50%.

(4) No person shall continue a CAT I precision approach to a runway with centreline lighting unless
(amended 2006/12/01; previous version)

(a) the air operator is authorized to do so in its air operator certificate;

(b) the aeroplane has a minimum flight crew composed of a pilot‑in‑command and a second‑in‑command;

(c) the aeroplane is equipped with

(i) a flight director and autopilot capable of conducting a coupled precision approach to 200 feet AGL or lower, or

(ii) if the flight crew uses pilot‑monitored‑approach procedures, a flight director capable of conducting a precision approach to 200 feet AGL or lower;

(d) the runway is equipped with serviceable high‑intensity approach lighting, high‑intensity runway centreline lighting and high‑intensity runway edge lighting; and
(e) a visibility report indicates that

(i) the visibility is equal to or greater than that set out in subsection (1),

(ii) the RVR is varying between distances less than and greater than the minimum RVR set out in subsection (1), or

(iii) the visibility is less than the minimum visibility set out in subsection (1) and, at the time the visibility report is received, the aeroplane has passed the FAF inbound or, where there is no FAF, the point where the final approach course is intercepted.

Basically this says that to use the 50% as set out in Column II of the chart below, you require these things. If not, you are stuck with 75%.

seems to me there has to be centreline lighting which pretty well rules everyplace but yvr out.

Just off the top of my head, YVR, YWG, YHM, YYZ, YMX, YUL, YHZ, and YYT all have centreline lighting on at least one runway, and there may be a few others. It may not seem like many, but then centreline lighting is only required to use (Ops Spec permitted) 50% of the published minimum visibility for approach bans on Cat 1 (ILS) precision approaches, which there aren't that many of either in Canada.

Thanks, that answers my question, this is very convoluted but how else would transport deal with anything

Approach Bans Or What happens when some of you just bloody ignore a hard number on your approach plate over the years. Big Brother swings into action and inconveniences all the rest of with regulations that.....a) justify somebody's employment. b) protect us from ourselves.
