Having worked with One-Elevens for many years, start seemed entirely normal. You're looking for a certain HP RPM and for oil pressure rising etc etc before you let the fuel in and then, on the 400, the start is cancelled manually by moving the start master to off at 50% HP RPM (cuts off the air from the APU) and you then hear the CSDS winding down again. Start Master then reselected for starting other engine. On the 500s the start cancelled automatically, big relay clunk!.

Well.. I don't know JS about most things as you all know but it didn't seem drawn out to me either I was equating the start to the Vanguard (not ideal I know).. bangers on.. start button depressed (auto off in 10secs).. when above 2000HPrpm reached, add fuel If HPrpm doesn't reach above 2000 in 10secs, you risk a hot start (a VERY hot start) but this was only ever a problem starting off the batteries. Sadly.. no APU on a Vanguard Wonder if we could get ASYD to start There is talk about spooling A4O's Conways up though sadly.. this doesn't include the addition of fuel
Nice bit of film that Yup.. I see what you mean.. that was a much faster start. There could be any number of reasons for the start 'delay' (if I can use that word) between the two. The Landor 1-11 was obviously much newer and that start may not have been the first of the day.. more a restart. The American 1-11 is a good deal older and that may have been the first start of the day so pressures/temps would be that bit slower to achieve I'm not saying that's the reason but it could be a viable explanation
When we did a 'first start' on PEP.. usually A.M and before Joe Public arrived, we used to face Mecca, twiddle rosary beads.. do whatever was necessary to give our Tynes an opportunity to surprise us and start For the 'public' run P.M.. things went much faster. I know that's an extreme but similar rules must apply
I noticed it because I only ever heard One-Elevens start like the landor one which was quite old then and would have more hours I think than the exec
Watching the Brookland starts of the Vanguard are very drawn out...in BEA service the first engines would be would up to high ground before the last one was even moving and although there was a bit of a delay in the first because the were busy, the last engine to start spent a lot less time on low idle before the wind up.
They were of course eager to get going.
but the drawn out constant note was something I'd not heard before on One-Elevens.
May not have been that unusual but just something I'd never noticed and stood out as being different to me.

It may depend on the temperature. I recall that if the temperature was above/or below (I can't remember which way) a certain mark then the HP cock would only be opened part way and once the engine had lit up opened fully to prevent a hot start.
