EXEMPTION NUMBER: CASA EX01/2004
CIVIL AVIATION ACT 1988
CIVIL AVIATION REGULATIONS 1988
EXEMPTION UNDER SUBREGULATION 308 (1)
LOW VISIBILITY TAKE-OFFS AND
I, WILLIAM BRUCE BYRON, Director of Aviation Safety, on behalf of CASA, under subregulation 308 (1) of the Civil Aviation Regulations 1988, exempt B767 aircraft operated by Australian Airlines Limited (Australian Airlines) under Air Operator’s Certificate number 582843 from compliance with the standard take-off and landing minima determined by CASA under subregulation 257 (1) and set out in the AIP (En-route 1.5, sections 4.2 and 4.3).
This exemption applies only in respect of take-off and landing operations outside Australian territory at aerodromes where air traffic control for that aerodrome has advised that low visibility procedures are in use.
An exempted aircraft
This exemption is issued subject to the conditions set out in Schedule 2.
This exemption starts to have effect on gazettal and ceases to have effect at the end of October 2006.
SCHEDULE 1
TAKE-OFF AND LANDING MINIMA
Take-off Minima
1.1Take-off Runway Visual Range (RVR) minima are 150 metres in the Touchdown Zone (TDZ), 150 metres in the Mid-point Zone (MID) and 150 metres in the Stop-end Zone (END).
Landing Minima
2.1Category II minima:
(a)landing RVR minima are 400 metres TDZ with 200 metres MID or, if MID not available, 200 metres END;
(b)landing decision height (DH) is 100 feet.
2.2Category III A minima:
(a)landing RVR minima are 200 metres TDZ with 200 metres MID or, if MID not available, 200 metres END;
(b)landing decision height (DH) is 20 feet.
2.3Category III B minima:
(a)landing RVR minima are 100 metres TDZ with 100 metres MID and 100 metres END;
(b)landing decision height (DH) is 20 feet.
RVR Requirements
3.1For take-off and landing, when the RVR in the TDZ, the MID or the END is less than 200 metres, then the RVR is required for all three zones.
3.2For take-off and landing, when the RVR in the TDZ is not less than 200 metres but is less than the standard take-off and landing minima, then a MID RVR is required, or if that is not available, an END RVR. If both a MID RVR and an END RVR are available then the END RVR is advisory only.
3.3In paragraph 3.2, standard take-off and landing minima means the standard take-off and landing minima determined by CASA under subregulation 257 (1) and set out in the AIP (En-route 1.5, sections 4.2 and 4.3).
Application of Minima
4.1If the take-off or landing minima set out in an aerodrome chart or approach chart are more restrictive than the minima that would otherwise be applicable under this exemption, the pilot in command must apply the more restrictive minima.
SCHEDULE 2
CONDITIONS
Interpretation
low visibility operations mean operations to less than Category I ILS minima, or take-off with less than 500 metres visibility.
Compliance
In order for pilots to conduct low visibility operations outside
, Australian Airlines must ensure the following conditions are met. Australia
Training
Australian Airlines must certify that the members of the flight crew have successfully completed a Low Visibility Operations training syllabus as set out in the table below.
Section of Course Contents Low Visibility Ground Training General concepts and appropriate definitions.
Aerodrome procedures, aids, markings, Cat II
and Cat III lighting systems and approach bans.
Factors affecting the determination of minima.
Reversionary minima.An understanding of aircraft maintenance requirements and serviceability.
Aircraft performance limitations.
Normal operating procedures.Non-normal procedures for handling pilot incapacitation, engine and system failures below 1000 feet, Alert Height (AH) and DH.
Low Visibility Simulator Training
(both day and night where possible)
Taxiing – low visibility.
Take-offs – minimum visibility:
Landings and Go-arounds – Cat II & Cat III:
- Normal operations
- Engine and system failures before and after V1
- Loss of visibility
- Normal operations
- Aircraft and ground system failures and loss of visibility at heights above and below AH and DH
- Pilot incapacitation
Take-offs and landings must be at high weights and at 10 knots crosswind.
Experience
4.1Prior to conducting Category II or Category III landings, pilots must have the following experience:
(a)Captains must have either a minimum time in command of 300 hours or 50 sectors, in Category II or Category III approved aircraft on Australian Airlines operations;
(b)Captains must have a minimum time in command of 100 hours on aircraft type;
(c)First Officers must have either a minimum time as First Officer of 100 hours or 30 sectors, in Category II or Category III approved aircraft on Australian Airlines operations;
(d)Captains must have performed a minimum of four autolands and First Officers a minimum of two autolands in Category I or better conditions, using low visibility procedures, on the aircraft type.
Recency
Captains
5.1In order to conduct Category II or Category III landings, Captains must have completed an autoland using low visibility procedures in a simulator or aircraft within the previous 90 days.
5.2Lost recency must be regained through performing an autoland in a simulator or in Category I conditions or better in an aircraft.
Aircraft
