Russian Style AH
I recently had the pleasure of a ride in the back seat of a Yak 9. The front cockpit instruments had all been changed to comply with western standards. However the rear cockpit retained the original Russian layout. The most interesting differance, to me anyway, apart from the altimeter measured in meters, was the AH. The colour scheme was the reverse of western models. In other words the sky was a dark colour and the ground in a lighter colour. I cannot remember the actual colour scheme.
Can anyone offer me an explanation for this?
I hope that this is the right forum for this question.
