Please forward your response to CASA by 10 April 2009 by one of the following means:
but the preamble PDF says reply by 23 Oct 09.
The key change proposals are
* General, performance based regulatory requirement for radio qualified pilots of radio equipped aircraft to make appropriate radio broadcasts at and in the vicinity of all non-towered aerodromes, with specific, recommended standardised calls published in educational and guidance material (CAAPs/AIP). PIC is to be responsible for broadcasting on the aerodrome frequency whenever it is reasonably necessary to do so to avoid a collision, or risk of a collision, between his/her aircraft and any other aircraft operating at, or in the vicinity of, the aerodrome.
* Carriage of serviceable VHF radio, and being qualified to use it, to be mandated for aircraft operating at or in the vicinity of aerodromes that are certified or registered (as published in ERSA) and other aerodromes designated by CASA (and published in ERSA) on a case-by-case risk basis.
* Introduce new provisions for the arrival and departure of aircraft with no radio, and for aircraft having unserviceable radio and for aircraft carrying serviceable radio which the pilot is not qualified to use.
* Withdrawal of CAR 166 paragraph (2)(d) and subregulation (4) - base-leg circuit join no longer prohibited.
* Amend CAR 166 paragraph (2)(f) to allow for non-into wind runway use when the AFM permits.
* Withdrawal of CAR 166 paragraph (2)(g) - 500m minimum length of the final approach leg no longer mandated.
* Withdrawal of CAR 166 paragraph (3)(a) – carriage of a serviceable VHF radio when conducting a straight-in approach no longer required (other than at certified, registered and other designated aerodromes).
* Withdrawal of CAR 166 paragraph (3)(b) – specific mandated broadcast for straight-in approaches deleted (although still recommended in CAAPs/AIP).
* Amendment of CAR 166 paragraph (3)(d) - reduction in the minimum distance from the threshold by which an aircraft making a straight-in approach must be aligned with the runway, from at least 5 miles to not less than 3 miles.
Oh gooodie.., now I can join on base for a 100m final to get in front of those wooosses doing 'standard' circuits. <g>
Lemme see now, someone not talking on the radio and on a 3nm final, + me on base not talking (because it's not mandatory) = change of underwear required.
