The 4 engine type that fly from City Airport - think they have an RJ designation.
What is going on when it sounds like they are starting up the additional 2 engines a few minutes after takeoff, and on landing sounds like they are switching off two of the engines during the approach??

BAe 146? There is one APU in the tail.What is going on when it sounds like they are starting up the additional 2 engines a few minutes after takeoff, and on landing sounds like they are switching off two of the engines during the approach??
Maybe it's the air conditioning packs.
Some aircraft when performance limited do 'packs off 'take offs as the aircon usually takes bleed air from the engines. They might need the extra umph for take off and then can switch the aircon on again after take off.
The packs might be switched off on approach incase of a go around?

One of the local Nanchang drivers flies the RJ from City, and I do remember him saying there was all manner of fertling around with the aircon packs that needs to be done in short order quite late in the approach for exactly that reason.Some aircraft when performance limited do 'packs off 'take offs as the aircon usually takes bleed air from the engines.

The BAe 146 and the RJ85 are very much one and the same plane.
The plane began life as the Hawker Siddeley HS146 but by the time it first flew in 1981, HS were part of British Aerospace. It was therefore known as the BAe 146.
Later on BAe in their wisdom decided to rebrand the aircraft as an Avro - even though the project had originally been drawn up by the old De Havilland team at Hatfield and it no lineage with the Avro division of BAe - except that some of the production was at the old Avro factory at Woodford (which is now going to close).
