is fit to perform the crew member's duties;
(f) a check to confirm that:
 (i) the aircraft's hatches, access ports, panels and fuel tank caps are secured; and
           (ii) the control locks, covers and ground safety devices and restraints have been removed;
(g) if the aircraft is an Australian aircraft — a check to confirm that there is either:
           (i) a certificate of release to service for the most recent maintenance carried out on the aircraft; or
 (ii) a maintenance release for the aircraft;
(h) a check to confirm that the aircraft's flight controls have been tested and are functioning correctly;
(i) for each system fitted to the aircraft for measuring and displaying pressure altitude, a check of the system's accuracy in accordance with the procedures mentioned in this Chapter;
(j) if an amount of supplemental oxygen or protective breathing equipment is required by or under the civil aviation legislation to be carried on the aircraft for a flight crew member for the flight — checks to ensure the following (as the case requires):
 (i) that the required amount of supplemental oxygen is available;
 (ii) that the protective breathing equipment is operative;
 (iii) that the oxygen mask is connected to the supply terminal;
           (iv) that each communication system associated with the oxygen mask is operative;
 (v) if the oxygen mask is adjustable — that the mask fits the flight crew member correctly.

10.03 Checking systems for measuring and displaying pressure altitude — general
       (1) For paragraph 10.02 (i), this section sets out the requirements for checking aircraft systems for measuring and displaying pressure altitude (pressure altitude systems).
       (2) If:
(a) an aircraft is at a known elevation (the site elevation); and
(b) an accurate QNH is available;
        then, before take-off, the pilot in command of the aircraft must check the accuracy of each of the aircraft's pressure altitude systems in accordance with this section.
Note   For accurate QNH and site elevation — see section 10.06.

10.04 Checking pressure altitude systems — IFR flight
       (1) The pilot in command of an IFR flight must consider any pressure altitude system with an error in excess of ±75 ft to be inoperative for the flight.
       (2) If 2 pressure altitude systems are required for the category of operation, then:
(a) at least 1 system (the first system) must read the site elevation to within 60 ft; and
(b) if the other system (the second system) has an error between 60 ft and 75 ft — the pilot in command may conduct a flight to the first point of landing where the accuracy of the second system can be rechecked; and
(c) if, on rechecking, the second system shows an error in excess of
