Once upon time at Essendon, it was a dark windy wet night.
As the dashing young handsome Capt Wally drives into work he notices the city lights reflecting in the low cloud and as he steps from the car he fills the cold biting southerly breeze drifting across the rain lashed airfield.
As he checks the forecast he notices most of the southern Victorian aerodromes are covered in low cloud and heavy rain, and the only reasonable places are on the other side of the ranges such as Mangalore.
The TAF for Essendon is showing a overcast cloud base of 500 feet and 3000m in heavy rain, the TTF for Melbourne shows a southerly gusting to 30 knots, broken at 400, ovc at 600 and visibilty of 4000 metres. The ARFOR shows a strong southerly starting at 30 knots at 2000' increasing to 100 kts at 18500.
As the good Capt Wally digests all this information, and ponders whether he should have a crapp, followed by a coffee and then think about preflighting either the trusty old B200 or this new fangled PC-12, the air ambulance flight dispatcher rings and says, "Wally your off to King Island, you know place where they have that really nice cheese, and which arcraft you takin?". Capt Wally thinks great middle of Bass Strait, winters night, low freezing level, **** that water will be cold!
Now the slick salesman said no worries this single engine job, she glide for miles, don't worry your pretty head about engine failures, its a turbine they don't fail. The guy that did the endorsement said the same thing, he certainly showed that it would glide and did everything by the numbers, but then it was a fine day.
Capt Wallly starts working the numbers, EFATO in the PC-12, probably struggle to get back round onto the Essendon ILS or some sort of cloud break procedure , what about engine falure in the cruise at say at FL210 will it be able to glide back for an ILS into Avalon, what about an EFATO out of King Island?
In the end Wally walks over to the old trusty B200, and light the fires and taxi's for rwy 17.
