Heard this term, and I'm not really sure what it means. Can somebody explain?
Sorry if this isn't the right place for this.

It's 'aircraft based' slang, really just means the majority of the ordered fleet (or sub-fleet) is in normal timetabled service right across the intended routes, and I'd say using normally rostered train crew.
Hence the opposite situation is that you might have a couple of early arrivals running around a subset of the network being used for initial training of staff, with only a small number of staff qualified to operate them.
As an example, you'd probably say that both the 458/5s and the 387s were not yet in 'squadron service'...
Oh, and welcome to the forums - this probably is the most suitable subforum for this type of question anyway.

I am not sure if this is relevent but the unbuilt production design of the Advanced Passenger Train was to be called APT-S with Squadron being the ''s''.
Yes, GrimsbyPacer is correct, that was certainly the case.Are you sure about that?

There's also APT-U (better known as the IC225). I have no idea what the "U" stood for. "Untilting", maybe?
Going off topic somewhat, but you're correct. APT-S would have had a power car at one end of the train, nine passenger trailers and a driving van trailer (idenitifed as such as early as 1981) at the other end; not dissimilar to the formation of the IC225s, but retaining vehicle articulation and tilt.I suspect APT-S would have had the power cars at the ends (or at one end) to avoid the impractical block in the middle.

Yes, I recall that as well (APT-P was Prototype, not Passenger).Neil
Here is some more info about the formations of the APT for you all to have a look at:

Wasn't APT-E given to the original gas-turbine unit (with the "E" standing for Experimental) and APT-P given to the production units (with the "P" standing for Production)
Hmmm in squadron service in the RAF means in active service.
