Altitude restriction on approach

[FullWings]

Here is another one cleared ILS across XXXX not below 2000’. The chart shows XXXX with 2000’ at that point with shaded grey below that. Unfortunately it’s ISA +20 so if you cross XXXX at 2000’ you have a significant fly down indication making the SAC a challenge. Any thoughts?

Follow the GS when you intercept it? You know why you’re going to be indicating low at XXXX (ISA deviation) so it’s not compromising obstacle clearance as the ILS occupies the same place in space whatever the weather. Further out the altitude restriction may be related to possible traffic separation, so I’d be a little bit more careful.
