I would be interested to know, which business aircraft is certified for 6 degree glide path. I know Legacy can do up to 5,5 degrees, ie london City, but not more.
Thank you

Falcon 2000, the 2000 without winglets wil even do 6,67 for Lugano

What is the relavance to Sion? It does not meet a steep approach criteria as the steep section of that approach already terminates at 7NM and the visual path continues with a 3.5° slope to the threshold, ensuring that aircraft performance and limitations can be complied with on landing and for the missed approach.

@ propellerpilot: OVC 090 what do you do ? you and the aircraft are either certified for 6degrees or you got to do a go around.
this IGS is not a localizer only approach. If you look at the Jeppesen plate G/S is mandatory.
Us in the Legacy have to treat it like Samedan and can only do a visual approach as the aircraft is not certified to follow a 6 degree glidepath. We can't accept an IGS approach but many other business jets do and that's why i was wondering who is actually certified to do it.
I expected the Falcons to be able to do it.
Propellerpilot is right - he describes the way most pilots/companies/authorities handle the sion issue.
The steep approach plates for your aircraft show the case of a final approach leading directly to touchdown (e.g. London City), where the aircraft needs to fly a stable approach and be able to do a safe g/a at the minium (taking into account the higher energy due to steep descent)
At LSGS the final approach is a visual 3,5° segment, as long as your aircraft is able to do a normal 3,5° ILS you´re fine .
For the IGS part, - fly in landing configuration or intermediate flapsetting - to fly at a stable speed and ROD - even with A/I on. I have not yet found a restriction on the descent angle for intermediate approaches or enroute descent in an AFM (but off course there might be one...)
my 2 cents
