That's no way to talk about your wife, pba_tgt!

If you want to develop your neck muscles, try a few sit-ups with some little lady perched prettily on your face!

Back in JP/Gnat/Hunter days, the leaden weight of the infamous Mk 2 bonedome didn't seem too much of a problem under +6 G (or even +8G once....oops!). Nor did the Mk 3A when I was on the Hawk. Even doing those painful +7 G extend and pitch back things...

In any case, just make sure that your in someone else's 6 rather than the other way round and the problem should be rather less!

I have heard the reason for Mk4 being worn in the Tucano is because the Mk10 is not yet cleared to penetrate tehe LCC in the front. Andy, all BFJT students now attend Gz tolerance centrifuge training to minimise risk of injury etc.

The reason the Mk 4 is still used at Linton is purely financial!

The Mk 10 should be issued from the outset...never mind the cost.

Usually more could than would with the lanky fellas coming through today.

Typically about 15-40 seconds depending on G threshold and how the QFI feels.

Not sure about that; ex fast jet QFIs with perfectly serviceable Mk10s are still given Mk4s to wear. It's probably the LCC; I imagine when it entered service the Mk4 was the best we had, and no-one's bothered to have the Mk10 approved for use with LCC.

Of course, that doesn't explain why an ex fast jet QFI can't wear his Mk10 in the back seat where he has MDC? Maybe it'd be too much hassle for the squippers to service two helmets per pilot?

Neeps, the actual reason (no duff, though can't remember which reliable source I found it out from, someone at henlow I do believe) is that every item of AEA has to be cleared for the aircraft in which it is intended to be used. So for instance your funky flappy kneeboard gizzas have to be cleared to ensure they don't interfere with the stick/throttle etc etc etc. In the case of a helmet this entails doing ejection trials to ensure that the helmet can withstand the forces involved whilst using that seat (note the Tuc is the only one without a rocket seat iirc (canberra anyone?)), through that canopy from that aircraft. The simple fact of the matter is no one can be arsed to pay to trial the 10 as when they carried out the early tests (required anyway) there were only 4's available.

Fromage: Is it every course? I heard on the vine of one course doing it but heard it was a one off trial with a view to mfts etc etc?

They'd still not have enough bags when you're off to the sim

(Hello to you and him, will we see you soon? And, what did they say?)

No way, does that mean you have to stay a full week at henlow now? Rather than bunking off for half the week? Shocker...

Nearly right; the actual actual reason is that the LCC fracture system in the front seat produces canopy fragments too large for the Mk10 helmet. It's in AP109B and phrased quite carefully to stop you wearing your Mk10 in the back.
