The control surfaces may be sampled alternately to produce the sampling interval of 0.5 or 0.25, as applicable.
16. Lateral control surface(s) position 7 18 Full Range ±2° unless higher accuracy uniquely required 0.5 or 0.25 for airplanes operated under § 135.152(j) 0.2% of full range A suitable combination of surface position sensors is acceptable in lieu of recording each surface separately. The control surfaces may be sampled alternately to produce the sampling interval of 0.5 or 0.25, as applicable.

22. Each Thrust reverser Position (or equivalent for propeller airplane) Stowed, In Transit, and reverse (Discrete) 1 (per engine Turbo-jet - 2 discretes enable the 3 states to be determined
Turbo-prop - 1 discrete
23. Ground Spoiler Position or Speed Brake Selection 12 Full Range or Each Position (discrete) ±2° Unless Higher Accuracy Uniquely Required 1 or 0.5 for airplanes operated under § 135.152(j) 0.5% of full range

Rudder pedal ±165 lbs ±5° 1 0.3% of full range For fly-by-wire flight control systems, where flight control surface position is a function of the displacement of the control input device only, it is not necessary to record this parameter. For airplanes that have a flight control breakaway capability that allows either pilot to operate the control independently, record both control force inputs. The control force inputs may be sampled alternately once per 2 seconds to produce the sampling interval of 1.
