Nic: That's on the CRJ, right? Although the thread starter did not specify I thought he was referring to Toulouse family where in the book it is not. I'm genuinely curious if you had that in your long haul days. Not that it may had not been substantial; although I struggle to find any cooling effect in 40° taxi or v.v. overheat in -5˜° holding. OTOH, once engineers require then it is settled.
