DUAL CONTROLS IN AIRCRAFT :
SAFETY PRECAUTIONS.
1. When an aircraft which is fitted with dual controls is to be flown otherwise than for instruction or by co-pilots, arrangements should be made to prevent any possibility of interference with the set of controls not in use.
2. Suitable protection may, in general, be provided by removing the duplicate control column and by disconnecting the duplicate rudder bar and engine and ignition controls, or by fitting them with covers which, whilst allowing free movement of the controls, would preclude interference therewith.
3. When, for the purposes of the grant of a certificate of safety for flight in accordance with the Air Navigation Colonies, Protectorates, Order, 1927, Schedule II, paragraph 7, a ground engineer is making an inspection of an aircraft in which provision is made for dual control, he must satisfy himself
(a) in cases where it is the intention for the aircraft to be flown for instruction in flying, or by co-pilots, that the duplicate controls are properly connected and in order, and
(b) in all other cases, that the controls which are not to be used are properly protected from interference by passen- gers and from being fouled by safety belts or harness or by other loose articles in aircraft.
4. Before commencing any flight, "the person in charge" of an aircraft fitted with dual controls must satisfy himself that the precautions outlined in this Notice have been observed.
