FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering. Proposed landing flap incorporates flap error detector. Every flap 1, 2 comprises transmission element 7 rigidly coupled with said flap 1, 2 to turn there about. Measuring lever 11 is rigidly fixed on measuring end of said transmission element. Pickup 12 is built in flap structure. In case error originates, flap 1, 2 twists to vary distance between pickup 12 and measuring lever 11. Pickup signals are transmitted to estimator device to localise errors of every pickup for said device to cut out flap drive via relevant actuator.
EFFECT: continuous control over flap twisting.
