Nota adicional1
The difference between roll and bank is that roll is movement whereas bank suggestes a fixed attitude of the aircraft. Consequently, a turn might be expressed in angles of bank: 'turn at a bank angle of 30º', and the movement to obtain the bank might be expressed as roll: 'roll the aircraft to the left'.
