Schedule 1          Instructions

1     The pilot in command of the aircraft is permitted to use GPS navigation equipment to:

(a)   navigate the aircraft; and

(b)   obtain positive position fixes for the aircraft.

2     Before commencing an operation for which the pilot in command of the aircraft intends to use GPS navigation equipment, the pilot must:

(a)   ensure that the GPS navigation equipment fitted to the aircraft meets the requirements of:

(i)  TSO-C129a, TSO-C145a or TSO-C146a, as published from time to time; and

(ii)  Advisory Circular 21-36, as published by CASA from time to time; and

(b)   ensure that a copy of the GPS operations manual is carried in the aircraft; and

(c)   nominate a suitable crew member to accurately maintain the line plot mentioned in paragraph 4 (a); and

(d)   plan for the maintenance of a special fuel reserve of not less than 50 minutes flight time, in addition to the operator’s mandated 60 minutes reserve, that is sufficient to enable the aircraft at any time during the proposed operation to track directly to the coast and to navigate either to an alternate aerodrome mentioned in paragraph 2 (e) or to the operator’s base; and

(e)   plan to ensure that, at all times during the proposed operation, there are suitable alternate aerodromes that can be reached within the special fuel reserve mentioned in paragraph 2 (d); and

(f)    notify the operator’s chief pilot that the pilot intends to conduct the operation using GPS navigation equipment.

3     Before dispatching an operation for which the pilot in command of the aircraft has notified the chief pilot that the pilot intends to use GPS navigation equipment, the chief pilot must be satisfied on reasonable grounds that the pilot is competent to operate the fitted GPS navigation equipment.

4     During an operation in which the pilot in command of the aircraft uses GPS navigation equipment, the pilot must:

(a)   ensure that, at 15 minute intervals, a plot line of the aircraft’s position is recorded by reference to the aircraft position indicated by the GPS navigation equipment and the time at which that position is recorded; and

(b)   ensure that the aircraft is at all times able to track directly to the coast and then navigate to either the operator’s operating base or an alternate aerodrome, within the special fuel reserve mentioned in paragraph 2 (d); and

(c)   if the GPS navigation equipment malfunctions or issues a RAIM warning:

(i)  cause the aircraft to promptly climb above the LSALT; and

(ii)  use dead reckoning navigation or a radio navigation aid, or both, to track directly to the coast and then to the operator’s operating base or an alternate aerodrome.
