I did a few approaches to London City… and while it’s a touch approach, it’s not impossible of course. All you need is to be fully configured for landing before you intercept the ILS glideslope. This means you might need to capture the G/S at VLS speed at full flaps and gear down. Let the G/S take you down, and disengae AP at the absolute last before you flare.
I’m planning to do some more approaches here but I’m waiting for the compatibility of the world update with ORBX London city scenery and the airport.
