Low Pressure Query

I have a question regarding low pressure settings and require your input...

What is the recommended procedure if you are given a altimeter pressure setting which is lower than can be set on the altimeter subscale i.e 940mb?

Thanks TF

Personally I would push the aircraft into the hangar, make sure the storm shutters are closed and secure and retire to the nearest bar!

Set QNE

You ask the airfield what your altimeter will read, on landing, when you have the subscale set to 1013.2 hPa or 29.92in (QNE).

I know a bloke who almost had to do it, taking a 737 into Luton on the night of 15th October 1987, the night of Michael Fish's Hurricane that wasn't. The pressure dipped to 95 something hPa.

I know another bloke, who knows yet another bloke, who once had to do it (allegedly)!
