Best to learn the mental math now.. then later when you travel west for the

I agree 100%.
It has been really interesting to watch this one. I fly in the UK and
this is what I have been taught to do:

If local then QFE;
if XC then QNH;
If wave flying then QNE once you go above 3,500 QNH (this is transition
round where I am I know it is different in other places). This also
applies XC if you are going near a lot of airspace;

I am taught to land without reference to the altimeter and I don't think
I have ever used it when I carry out field landings.

Not that many glider pilots in the UK have radio licences and a fair
number of gliders do not have radios so the QNH is not generally updated
beyond the departure calculation and setting.

Now, I must say that this is a reworking of what I was taught for power,
not gliding and I can't remember it ever being laid down specifically
what I should do away from local flight other than making sure that I
could land and so on without use of the altimeter.

Cheers
