Wind and Altimeter Setting
I've been told that if, on a long cruise, the plane drifts left (port) then the altimeter will read too low. For the life of me I can't work out why that is the case. I thought that if I was drifting left the plane would be moving towards a low pressure system (or away from a high pressure system) since in high pressure systems the wind blows outwards, and inwards in low pressures systems.
I would be grateful if anyone could explain what I've got wrong. Thanks!
