• the place is an aerodrome established under theAir Navigation
Regulations; or
• the use of the place as an aerodrome is authorised by a certificate, or
registration under CASRPart 139; or
• the place is an aerodrome forwhich an arrangement under section 20of
theAct is in force and the use of the aerodromeby aircraft engaged in
civil air navigation is authorised byCASA under that section; or
• the place (other than in points 1, 2 or 3) is suitable for use as an
aerodrome for thepurposes of the landing and taking-off of aircraft; and,
having regard to all the circumstances of theproposed landing or take-off
(including the prevailingweather conditions), the aircraft can land at, or
take-off from, the place in safety. Guidance as to the suitability of such
aerodromes asmay be found inCAAP92-1(1) ‘Guidelines for Aeroplane
LandingAreas’.
PAVEMENTCONCESSIONS
A pilot planning a flight by an aircraftwith tyrepressures and/orweight in
excess of that permitted byAGAmust ensure that a pavement concession is
obtained.
EmergencyLandings.
When safety is involved, thenearest aerodromewhich
will permit a landingwithout danger to the aircraftmay be used, irrespective
of thedamage thatmay be caused to the pavement.
Mercy Flights.
Decisions should bemade in accordancewith thedegree of
urgency involved. Severe overloading of pavements is acceptable if the safety
of patients, crew and aircraft is not thereby jeopardised.
CIRCUITHEIGHT
By convention, the following circuit heights areflown;
• Highperformance, above 150 kt, 1500 ft AGL
• Medium performance, between 55 kt and 150 kt, 1000 ft AGL; and
• Low performance,maximum 55 kt, 500 ft AGL
Circuit heights for aerodromeswhich have specific requirements are
published inERSA.
