View Full Version : Visual slope guidance and jet aircraft

I remember reading somewhere that ICAO? PANS OPS? mandate that jet aircraft should not be landed on any runway without some sort of visual slope guidance (PAPI, VASI etc).
Can anyone verify this and maybe quote a reference? Thanks.

That would appear to contradict CAT IIIB and autoland as a concept, no? Would seem a bit unlikely.

You may be technically corret, but I doubt there are many CatIII runways that don't boast a VASI/PAPI

I wonder if it might be "precision approach guidance" that is needed rather than 'visual slope guidance'.'

Hopefully quoting safetypee's useful contribution from a discussion on steep approaches is in context
The original ‘jet’ certification at LCY required ‘precision’ approach guidance, being either ILS GS or PAPI; thus if the ILS is u/s, PAPI is mandatory.

Yall have obviously never flown in France. ILS without PAPI is standard, NPA without PAPI is common. But when did France ever follow ICAO?

ICAO Annex 14 (http://dcaa.slv.dk:8000/icaodocs/Annex%2014%20-%20Aerodromes/Annex%2014%20Volume%201,%20Aerodrome%20Design%20and%20Operat ions%20-%20Edition%20no%205.pdf) requires that runways be equipped, but not that aircraft should not land without guidance.
Operations are in Annex 6 (nothing found).
Annex 14
5.3.5 Visual approach slope indicator systems
5.3.5.1 A visual approach slope indicator system shall be provided to serve the approach to a runway whether or not the runway is served by other visual approach aids or by nonvisual aids, where one or more of the following conditions exist:
a) the runway is used by turbojet or other aeroplanes with similar approach guidance requirements;
b) ...

Don’t forget to check “Contracting States which have notified ICAO of differences”.

P.S. In my day, the ability of a pilot to complete a landing without approach slope guidance used to be a UK CAA requirement.

Thanks guys. I suppose Annex 14 was the reference I was looking for.
