approach ban

in commerical approach ban- non ops spec-

commerical operator
non ops sepc
runway LOS is standard

a/c is prior to the faf, if rvr is varying between distances less than and greater than the minimum RVR for the approach ban, which is 3/8sm or 1600RVR for an advisory value of 1/2SM or 2600RVR (1500V2100) but metar reports 1/4SM the approach is not banned but the aerodrome operating visiblity is below taxi minima so the aircraft cannot land.


commerical-non ops sepc- approach ban
The following exceptions to the above prohibitions apply to all aircraft:
• when the visibility report is below the required value and the aircraft has passed the FAF
inbound or;
• the pilot-in-command has informed the appropriate ATC unit that the aircraft is on a training
flight and that the pilot-in-command intends to initiate a missed approach procedure at or
above the DA(H) or the minimum descent altitude, as appropriate;
• the RVR is varying between distances less than and greater than the minimum RVR;
• the ground visibility is varying between distances less than and greater than the minimum
visibility;
• a localized meteorological phenomenon is affecting the ground visibility to the extent that the
visibility on the approach to the runway of intended approach and along that runway, as
observed by the pilot in flight and reported immediately to ATS, if available, is equal to or
greater than the visibility specified in the CAP for the instrument approach procedure
conducted; or
• the approach is conducted in accordance with an Ops Spec issued in accordance with
subparts 703, 704 or 705 of the CARs.

AOS - landing:
Where the aerodrome operating visibility as set out in subsection (A) is less than the
minimum visibility published in the CFS, a landing is deemed to occur below the published
aerodrome operating visibility for the runway of intended use; except where:
• at the time a visibility report is received, the aircraft has passed the FAF inbound or where
there is no FAF, the point where the final approach course is intercepted;
• the RVR for the runway of intended landing is varying between distances less than and
greater than the minimum RVR and the ground visibility is equal to or greater than the
minimum visibility;
• at sites without an active ATC Tower, the ground visibility is varying between distances
less than and greater than the minimum ground visibility and the RVR is equal to or
greater than the minimum visibility; or
• at sites without an active ATC Tower, prior to 1,000' above aerodrome elevation the PIC
determines that a localized meteorological phenomenon is affecting the ground visibility
by observing that the runway of intended landing and the taxi route to the destination on
the aerodrome are seen and recognized.

true or false?

An RVR report takes precedence over a runway visibility report or a ground visibility report, and
a runway visibility report takes precedence over a ground visibility report. Ground visibility will only
impose an approach ban at aerodromes south of 60°N latitude. If no RVR, runway visibility, or
ground visibility is reported, there are no criteria to impose an approach ban. (This concept is
similar to the present Subpart 602 of the CARs approach ban, where if there is no RVR reported;
there is no criterion to impose an approach ban).

So in this case rvr is reported and say the aerodrome is south of 60, so the rvr report takes precedance over the ground vis.
