Just to add a little more to rapidex; we set an initial spool up setting that equates to around circa 40-45% of the engines rated power dependant on engine type. On GEs CFMs and CFs it’s a percentage of N1(front of engine) fan speed. On the likes of RRs or IAEs it’s an engine pressure ratio or EPR. This enables any early gremlins to be identified but also allows for uniform and symmetric application of the take off power/thrust setting for that particular take off.
There is a spool up prior to the final application of take off power regardless of type. I think only Concorde avoided that and even turbo prob types do this.
Personally I’ve found RRs take the longest to achieve the take off thrust setting from hitting the TOGA switches. CFM 56s on the 737s would spoil up fast but would pause for a moment prior to ‘trimming’ up to the final N1setting. This prevented the auto throttle over setting the take off N1. Pretty much all engines ‘gain’ from a ram rise effect during the take off run. I find that from commuting on the 320 fleet that they spool up quite quickly but the NEOs seem to take slightly longer too, but with larger fan blades this is hardly surprising.

Nice to see the Ask the Staffer thread back - as I’m sure there will be a few questions regarding changes in this new travel day and age.
I flew BA today on 209 - LHR-MIA, and noticed a new addition to the crew, and was curious about it.
As well as the cabin service manager, who I guess is responsible for the whole crew etc, there was another silver tie cabin crew member, who spent a long time coming up and introducing himself, and welcoming us gold card (and above) back on board. He spent a good 5+ minutes with each of us in Club - about 5 of us I noted. His job title badge - sorry I forget the exact title - was like Cabin Experience Manager - or words to that effect. Not one I had seen before. He seemed extra to the 2 crew assigned to each side of the airplane, but mucked in as where required, delivering food drinks etc.
He came by often, especially to the GCH’s, to check everything was alright inflight, did we need anything else, asking if anything not quite right etc.
I fed back that from wheels up to first drink offer - 1 hour and 15 mins, was too long IMO. He agreed, and said crew were being flung onto aircraft and not sure what was where etc, and it was just taking a little bit longer, on the now totally full TATL flights. Meal service to tray removal, was almost 3 hours from takeoff. I mean I don’t care much as its a day flight, and I haven’t got much else to do, but on a night flight return, that might be an issue for some.
Wonder from those in the know, if this is a permanent position, or just a thing whilst BA get back in to their groove….. the CSM didn’t come speak to us once, just got on with her job. Which was fine, as the other crew member did the FF welcome pleasantries instead.

There is a spool up time requirement for civilian aircraft, from memory i think it is 6 seconds?

Hong Kong Crews
I follow a Cathay Pacific B748F pilot on Instagram and she, along with over 100 CX crew were ‘detained’ in Hong Kong’s quarantine facilities last week due to 3 CX pilots contracting Covid on a Frankfurt stop-over. While most of the CX crews have now been released, I read that a BA crew were detained this past weekend and could be held for up to 21 days in quarantine, which is certainly not what any crew have signed up to. How is the entire HKG quarantine situation impacting crewing for these flights (I am guessing nobody wants to staff these flights given the above issues) and are BA looking at bringing back the no-crew stay down route option for this service?

Are they still being detained in breeze block pre-fabs, Camp Tenko style? I'm not sure this is HK's best method for returning to the international stage, but by all accounts that ship sailed some time ago (and possibly on the RYB).

Sadly yes - this is Hong Kong’s quarantine camp on Penny Bay
Picture Credit - Not mine but would rather not post their details on this forum.
