inbalance,

Might I ask how you are measuring angle of attack ? .. presumably there is a measure involved, else how can you assert that the value remains the same when you bank ...... ChrisVJ's comment that the alpha increases in (steady) level banked turning flight (compared to straight and level flight) seems reasonable as the lift vector must increase to provide for an horizontal centripetal force and mass-balancing vertical force ..... that seems to suggests an increase in alpha .......

At its simplest, alpha is a matter of whence cometh the wind, viewed from the aeroplane's axes, in elevation, in respect to the wing section ... if the direction changes then the alpha changes ... anything which can cause such a change .... is of relevance to the original question I would have thought ?
