Do Skippers use an Anti-Icing agent in their fuel?
When I operated C441 a long time ago it was recommended that an agent like Prist was used above F250.

Hi Wingnut

FlightAware has the acft going BRM-FTZ-HLC | HLC-FTZ-BRM.

BEW of our Conquest is about 2850kg. Skippers might be less. MTOW with all the mods is 4690kg. MLW varies according to Mod status.

Fuel burn is about 700lb/hr.

10 POB + bags = ~860k. Looked like mostly women from the video I saw on line, so payload might have been less.

4690 MTOW -860kg pax - 2850 BEW = 980kg/2160lb available for fuel.

From my flight planner that leaves me back at Broome with a margin of 8 minutes over IFR reserves...... :hmm:

If the aircraft is a lighter BEW and the passenger load weighed less, they (presumably) would have been carrying even more fuel and would have had a greater margin.

Ooooo ... OK, thanks for that.
It's not what I expected.

There was no fuel uplifted on the highway. Unless of course there is a secret squirrel method of doing this.

This certainly is getting interesting!

Yes it is. All the evidence seems to discount the "dumb pilot didn't carry enough fuel" theory.

Yes, had considered that.

Also, for the return leg, would you have included Curtin or Derby as an alternate?
For the 40 km hop across the bay would they still need that? Assuming that you had used an alternate in your numbers.

No reflection on what happened, just curious.
They obviously had enough fuel for the final hop.

What's the fuel system on them HLB, is it all in via the one tap or is pumping/transferring required?

Left tank to left engine.
Right tank to right engine.
Crossfeed valves operated by solenoid.
Couldn't be simpler I would have thought!

I refuelled many Conquests over the years & Prist was never added to any of them.

It's a flight manual requirement to use FSII or equivalent.

Like I said - I refuelled many over the years & the pilots never put Prist in. I can't remember putting Prist in any turbine aircraft, although I may have & just forgotten about it because it was an infrequent occurrence. Can remember putting it in plenty of jets though.

FSII is a flight manual requirement for PC12s also and there are plenty of those floating around...

Never put Prist in any of those either!

Not every uplift though. Just a certain concentration required. Mob I flew that for worked out that on average every two to three uplifts was sufficient, and that usually meant it was only required at Home base (BP truck with FSII available).

Fiddling around with the pressure pack, tube and clip, hated the stuff

Apparently the new cans come with a trigger dispensing system - much easier!

How do you know this, Eddie?

You never flew a Citation then.

Working on a cattle station nearby, happened to be on the Highway when the blokes from Skippers arrived.
Be at north west air spares sometime today. Surely they will know the duff gen on this.
