           13.      monitor aircraft systems, manage fuel and engine to ensure aircraft is operated to achieve flight plan objectives.
     5.               NAV.5 – Navigate at low level and in reduced visibility
            1.        configure the aircraft as required for the following environmental and operational conditions:

                   2.         low cloud base;
            2.        navigate aeroplane at minimum heights (not below 500 ft AGL, clear of built-up areas) and remain in VMC;
            3.         maintain separation from terrain, obstacles, allowing for wind and turbulence at low level;
            4.        avoid noise sensitive areas;
            5.        operate appropriately in the vicinity of aerodromes and landing areas.

            1.        acknowledge positional uncertainty in a timely manner;
            2.        configure aircraft for range and endurance as required;
            3.         apply recognised method to re-establish aircraft position;
            4.        fix position;
            5.        use radio to request assistance, if applicable;
            6.          plan a timely precautionary search and landing if unable to complete flight safely to suitable aerodrome.

            1.        make timely decision to divert;
            2.        identify an acceptable alternate aerodrome;
            3.         select a suitable route and cruising level;
            4.        revise flight plan considering weather, terrain, airspace and fuel available;
            5.        advise ATS of an intention to divert.
     8.               NAV.8 – Use instrument navigation systems
            1.        initialise navigation system (as applicable);
            2.        conduct navigation system validity check (as applicable);
            3.         conduct RAIM check if required;
