Quick question on Tridents for Peter M.

[Speedbird217]

Hi Peter,

I was thinking about my many flights on Tridents (1,2 and 3) on the Edinburgh and Glasgow shuttle runs and remember one cold winter morning I was on the first flight of the morning out of Glasgow, 7am I think. What I remember clearly as I was sat at the back, was that we taxied towards 23 and then stopped in a holding area. The Captain announced he was going to "warm the engines up" as there had been a frost overnight and this was the aircrafts first flight of the day. He then proceeded to run the engines at something like 50% (maybe less) for about 5 or 6 minutes.

In all my early morning Trident and 1-11 flights I only experienced this once and I don't think it was even that cold that day. My question is whether this was SOP from the Speys manual or warming the engines fulfilled another purpose? It was a 3B if that is relevant.

Cheers,
Robin

I had a 757 captain do the same thing on an evening flight from EGLL - EGAA in Feb '87

Robin,

I'm surprised that I can't recall an SOP for that on the 3B, because I spent 10 years captaining same...I wonder if some gauge anomaly occurred while taxying out and the engine run up was deemed a practical method of resolving it, rather than taxying back to the stand. The passengers would have been disturbed by such a procedure without an announcement so...

Was that during my Trident period (March 1975-December 1985)??

Hi Peter,

Thanks for the reply. Interesting that it might have been a gauge niggle.

Timing would be around 82/3 - I used to love the Trident 3 flights, always a great ride.

Cheers,
Robin

Hi Robin,

Well I guess we must have flown together a few times...I did quite a lot of shuttle. I had not realised that you were ever on Tridents
