The British ASI

[bolox]

one thing that has caught my attention since release is the needle behaviour of the British ASI's:- there is a marked drop in indicated speed as G is pulled, something that definitely doesn't appear with German instruments.
I can think of no reason for a difference in the behaviour, both being similar systems

While we're talking asi's- what is going on with the hurri and blen asi?
i've never seen a British asi(of the period) with dual needles, all having a single needle as depicted in the spit

spit/huuri asi


320 mph asi blen (and many others)
