As I understand the present Mt Cook contract to be:
Mt Cook has a banded salary scale system in their contract which allows for weight category. It is not type specific.
At present they operate ATR 72 - 500's which fall between a weight band of 20000 - 25000 kgs.
For F/O's their salary scales for basic salary $44186 to $63514 and for Capt's $77322 to $104939.
There are Training and Supervisory margins paid on top for those that are appointed to Training/Supervisory positions.
They range from $4000 to $13899, depending on position/responsibility
Five days off are rostered each fortnight, the fifth day can be called back, after roster issue, with a choice of either a day off to be taken within the next two roster periods, or the pilot receiving a payment of 1/206th of basic salary in lieu of the day off.
New contract conditions allow only two call-backs per month.
Other allowances can be between $10000 and 15000 pa.
