The mark on the airspeed indicator for 400Km/h on the yak-9M, and possibly other yaks too is in the wrong place, the needle passes the 400Km/h mark at 350km/h IAS. The airspeed indicator changes scale by 50% to larger increments at 300km/h, but the needle doesn't take this into effect until 400km/h, causing a 50 km/h difference in IAS. Hope I'm making sense here!
