ED Decision 2022/007/R

- (a) An automatic landing system shall include automatic control of throttle/thrust to touchdown unless it can be shown that: - (1) the aeroplane speed can be controlled manually without an excessive workload in conditions for which the system is to be certified; - (2) with manual control of throttle/thrust, the touchdown performance limits of CS AWO.A.ALS.106(c) are achieved; and - (3) the touchdown performance is not critically affected by reasonable errors in speed control. - (b) An automatic throttle/thrust system shall provide safe operation taking into account the factors listed in CS AWO.A.ALS.106(a). The system should: - (1) adjust throttle/thrust to maintain aeroplane speed within acceptable limits (see AMC AWO.A.ALS.105(b)(1)); and - (2) provide throttle/thrust application at a rate consistent with the recommendations of the appropriate engine and airframe manufacturers.
