Tinstaafl,
aaaah, a change of position! Missed that one.
In previous episodes of the 'Yawing, slipping and sliding about' miniseries:
Any multi having engines outside of centre line will be sideslipping during straight flight when there is any imbalance of thrust.
Sorry - any multi, not including those with centre line engines, having ANY measure of asymmetric thrust will be sideslipping in straight flight whether wings level or banked.
Add 'balanced' into the mix and it's a whole new ballgame (pun unintentional). Cunning, Milt, very cunning indeed!
Cheers,
Fred
