Back engine overheating on ground

[Bob Cook]

Concurr This is normal.

You need the front engine to supplement the cooling on the rear. If I taxi with one engine I will do it with the rear if the OAT is below 40 deg and then I watch ALL temps.

It is a tradeoff as you end up with FOD when taxing with the front at higher power levels (required with one engine taxi).

If there is a pileup for departure I always make a comment that if I do not get moving soon I will need to shut down the rear engine. Zoom-- to the head of the pack. Works every time (when needed).

fyi
