Right, of course! Operating costs are traditionally higher for helicopters right? So based on this a replacement for the Bou is required and some chooks maybe on the horizon. Do we really need the capability of the Bou's? Will we be required to land on rough/short fields?
The ADF will always need an ability to land in rough and short fields. Chooks are tremendous, but Caribou's are freakin amazing. They fly so slow you'd swear they're going to fall out of the sky, but somehow they don't.
They just drone along, bank sharply and land in ridiculously small spaces. The Bou's carry heaps more (roughly double the payload) and fly further and funnily enough faster (though it doesn't look it to the naked eye) than chooks. Chooks of course can land and takeoff vertically, but Bou's only need a couple of hundred meter's or so...
I saw a Bou take off under full tac flying conditions at an unmarked strip in the middle of Shoalwater bay once and I'd swear it landed and took off in less than 100 m's. It was unbelievable.
Keep the Bou's I say. There's a bit of nostalgia about them... Just give them a decent modern (and cheap engine) and a bit of an airframe upgrade, they'll be sweet for years and cost bugger all. The rest of the money can go on more chooks...
