Hi chaps,

I am not familiar with cold wx ops, as we do not have them in our network, but I already read a lot about it (just for the sake of learning it) and just wanted to clarify something pertaining ILS approaches:
The way I see it, when flying an ILS the G/S per se is not affected by the temperature, at is is an electronic beam, it will guide me on a 3º path to the runway.
Now comes the doubt, the check altitudes, on the other hand, will be affected by the temperature, and I will expect to cross them lower than mentioned on the chart, even if I am on the G/S? Can I assume that terrain clearance is guaranteed as I am following the G/S?

Thanks!
