A400M

You are correct.

The UK C17 has a very limited PARA capability (free fall only I am led to believe). Certainly no static line, side door or ramp LLP cap, and definitely no resupply air drop cap.

Not sure what is meant by the phrase 'serious jumping' in connection with UK C17 or indeed any other UK ac.

PhotEx - Can you expand on when the FR 'once more' borrowed UK C17 for para role (or serious jumping)? Not a dig, serious question.
when you read that a multi-million dollar aircraft like the C-17 (RAF version, whatever that is) can't be used for static, side door or ramp dropping of humans or kit, then you have to wonder how the Russians were are are able to do it from the IL-76, decades ago, with the troops jumping ahead of the engines sans static lines.....perhaps someone ought to take that nice Mr Boeing to one side and clout him/her/itabout the head until they make the C-17 (RAF) work from the off, instead of down the road, several billions of dollars later.
 
Are they still leased? I thought they had been bought outright after they started clocking up a stupid amount of hours.
Bought outright.

wow! who dreamed up that contract!!??
The Govt and the RAF decided upon that contract as it was the right thing to do at the time. We have C130's and now A400 ATLAS (in the T&E phase) to provide airdrop capabilities. C17 was and is regarded as a Strategic aircraft (it has jet engines) while the latter I mention are more Tactical for airdrop (aircraft with propellors are normally better at airdrop to allow slower speed when despatching, along with other attributes).

If the UK MOD decide that our C17s should take on an airdrop role then (similar to the USAF) we could do it if necessary. Until there is a UK defence requirement (and the money) we do not need to.
 
I suspect that as we use a different parachute system to the US the usual paperwork and testing will have to be undergone and the sops written. On a highly used asset, that might mean putting it off ( especially as the C130s can do it ).

Oldsoak - You are on the money. Yes, the UK does employ different parachute types (and AD systems in general) to our US allies. And as you rightly state to take a C17 off the line to conduct all the trials and evaluation may not be worth the time and effort right now.

If there is no current requirement for UK C17 to airdrop there is no need to add more workload onto the T&E specialists who are working hard on A400 ATLAS and C130J airdrop projects.
 
C17 and Herc aren't exactly quiet either :)
Subjectively, the A400m that went over last week at 10 000 feet sounded as loud to me as a Herc at 500'. Anybody got official figures on noise levels? Or anybody living near Brize who can stick a dB meter app on their phone and give us a more impartial judgement, I'm halfway across the country these days.

Here are some figures from DIO:

C130 EGR Noise Assessment Technical Report

Figure 5.7 is a reasonable view - A400M is ~20% noisier than C-130.

What surprised me was that VC-10 was quieter in almost all respects.

Disclaimer: the report was produced by AMEC on behalf of DIO. I don't know if the figures have been re-assessed or validated since the introduction of A400M into service.

From what I can see the amplitude scale is in decibels. Decibels is a logarithmic scale, so a change of 20 db is equivalent to an increase in amplitude of a factor of 10.

And that's the first time I've heard the term "quiet" applied to the VC10, from the outside at least, it always had a reputation for the quiet inside on account of having the engines at the back.
Thanks for the wonderfully informative response, just what I was ]hoping for.

Odd graph. C130 full power inboard and normal speed ground idle outboard while A400 full power ? How does that comparison add up ?

#3657 if you want a comparison between C130 and A400 in the air.

No he can’t, because like most else he says it’s bollox.

It possibly originates from the tests Marshall Aerospace did when they fitted the TP400 to XV208 on the port inboard station.
