Definition#
Roll is the rotation of an aircraft about its longitudinal (front-to-back) axis. Rolling left tilts the left wing down; rolling right tilts the right wing down. Roll produces the bank angle needed for turns.
Why It Matters Operationally#
Roll rate and bank angle determine turn rate and radius. Excessive bank angle increases load factor and stall speed. Turbulence causes uncommanded roll that pilots must correct.
