Interesting to note that, as well as No 3 being started first as per my recollection (9:00), taxy in after landing was on the outers only (1:30).
I'm almost certain that the BEA start sequence was 4-3-2-1 (I flew for 5 years on this fleet). Also the Tynes on the BEA fleet had different limits from the TCA aircraft:
permitted T/O LP RPM range 15,050 (min) to 15,500 (max)
max continuous HP RPM 17900
Except at high airports temps min torque for take off was 430 units (engines 2 & 3) and 450 for 1 & 4. This was because the inners also powered the pressurisation compressors. During conversion to Merch config the eng 2 compressors were removed, presumably to reduce costs. At high airport temps the HP cock trimmers were set to lower settings, which of course reduced the min required T/O torques.
It looks like the TCA Vanguards cruised at higher LP RPM than BEA. Maybe fuel economy (and maintenance cost) was less critical in those days.
