I flew the 1E for Pakisatn International Airlines. In the winter months it flew like a 1960s fighter with a 3-4000ft rate of climb and cruised a Mach .88 at 37000ft. In summer it was a pregnant duck. On a take off from Lahore at 40C plus for Dacca my briefing to my F/O and F/E was: '...you will call out:"ROTATE" and I will apply back pressure on the control column--you two will grasp the sides of your seats and pull upwards vigorously!' We used to get a good look at the bushes and trees at the runway end even though the nose was canted the usual 20 degrees up. Mr. Floyd was right, we had three Spey engines and had water injection, without which we would never have got off in summer. That said, she was a lovely aircraft to hand fly and had a unique auto pilot far ahead of its time. The A/P had seperate 'ON' switches for aileron and elevator control.
The A.P.U (Auxiliary Power Unit) which was used to start the main engines was originaly situated in the belly of the aircraft.The B.E.A. fleet were modifid at heathrow and moved the A.P.U. to the tailplane above #2 engine.
As correctly noted the Trident 3 had a fourth engine namely a tail mounted R.B.162 booster engine to enable it to get off the ground!

the APU was under the rudder (above the #2 eng) In the 3B this was upgraded to a 10,500lbs eng for hot & high takeoff.
After all it normally took the curvature of the earth to get Trident into the air.
The Hawker Sid Tridents operated by the Pakistan International Airways had three engines. This comment based on experience as a passenger during 1966 in Pakistan.
The Trident 2E had three Rolls Royce Spey RB163-25 Mk512 turbo fans as noted.The original engine was to be the still born R.R.Medway DeHavillands having to replace this with the Spey (essentially a military engine. As correctly noted the Trident 3 had a fourth engine namely a tail mounted R.B.162 booster engine to enable it to get off the ground!
The engine was the Spey - a Scottish river a few miles from Lossiemouth. NB all RR jets are named after rivers - from Derwent to Trent. If the site owners fix the typo, please remove this comment.

Does the Hawker Siddeley "Trident" 2E REALLY have four engines? The Trident 3B had four, but one was much smaller than the R-R Spay.
