Budget1 - you also misunderstand my comments re NVG; at the moment the MCA crews do a certain amount of night flying training for currency which probably doesn't affect the 2000 WTD since when it gets dark early and you are deemed to be inside your 'daytime' duty period. But as the nights get shorter and more night flying training (for NVG) is required, some of this training burden will start to impinge on the 'night duty period' and therefore count the same as being called out at night ie the whole period goes towards the 2000 hr WTD figure.
Post SAR H - if a service 'no less capable than at present' is to be maintained then the training hours of civ SAR crews will have to ramp up, whether they are ex-mil or not since the CAA, who have resisted legalising civvy NVG ops for so long, are likely to impose strict training and currency requirements when they finally capitulate to the overwhelming pressure.
