fittings, except that fire resistant seals may be used where the openings concerned would not allow the passage of a hazardous amount of flame in the absence of seals.
EQUIPMENT
3.24 Instruments and indications

 (1) The scale graduations of airspeed indicators shall be in knots only with the scale as close as is practical to the periphery of the dial. The numbered graduations shall commence at a speed lower than the power-off indicated stalling speed of the aircraft in the landing configuration and at the minimum weight operationally possible.

 (2) The height scale of altimeters shall be graduated in feet.

 (3) The barometric subscale of sensitive altimeters shall include a calibration in millibars in increments not exceeding 2 millibars.

 (4) Magnetic compasses shall be corrected and calibrated in accordance with section 108.6 of the Civil Aviation Orders.
 (5) A landing gear position indicator is required if the aeroplane has a retractable landing gear.
3.25 Safety harnesses and inertia reels

 (1) Each occupant shall be provided with a restraint consisting of at least a seat belt complying with section 108.42 of the Civil Aviation Orders or as otherwise approved by CASA.

 (2) Each pilot seat and each cockpit front seat shall be fitted with a safety harness complying with section 108.42 of the Civil Aviation Orders, or as otherwise approved by CASA, and shall incorporate, where necessary to achieve compliance with paragraph 3.25 (3), an inertia reel complying with section 108.42 of the Civil Aviation Orders or otherwise approved by CASA.

 (3) Each pilot with his seat, safety harness and any adjustable controls correctly adjusted for normal flight shall be able to:
 (a) without interference produce full and unrestricted movement of each control which he may be required to operate in flight, both separately and with all practical combinations of movements of other controls; and
 (b) at all positions of each control exert adequate control forces for the operation to be performed.

 (4) The seats and restraints shall be designed to withstand the emergency load factors specified in paragraph 3.19 (1). An additional factor of 1.33 shall apply to the fittings transferring the emergency loads to the airframe.
OPERATING LIMITATIONS AND INFORMATION
3.26 Operating limitations

 (1) Operating limitations shall be established and shall be approved by CASA. These limitations shall include all those upon which the aircraft design is based and all those which are applicable to:
 (a) weight and c.g. limits; and
 (b) loading; and
 (c) power-plant; and
 (d) airspeed; and
 (e) flight handling, including acrobatic manoeuvres.

 (2) Acrobatic manoeuvres may be permitted where the airworthiness and structural integrity of the type has been justified to acrobatic standards to the satisfaction of CASA by the submission of:
 (a) evidence that
