All,
For those of you a trifle reticent about “slipping” him bigfella balus, all B757/767/744 on an autopilot coupled approach, below 500 ft, handle cross wind by side/forward slipping ( take your choice) admittedly in the case of the B744 a combination of crab and side slip.

A B767 is all sideslip with the aircraft centreline aligned with the runway below 500’, in a max (A/P) crosswind the wing down is about 7 degrees, and it does it beautifully.

As for D.P Davies, with all due respect to his fans, I would strongly suggest you take some of his pronouncements with a grain of salt, in fact he had very limited experience on large aircraft, but that did nothing to moderate his views.

He also had a highly developed "not invented here" complex, that was not trans Atlantic limited, it also applied cross Channel. The Caravel was never certified in UK, ( the forward fuselages were originally built by Dh).

Furthermore, aircraft handling characteristics have improved greatly since the late 50’s and early 60’s, just fly your current party transport to it’s sops, not according to Dai Davies.

Quite frankly, some of the modification demanded to B707-300/320 on the G- register (non Boeing stab trim settings for T/O, modifications to the spoiler isolation system to solve a non problem, but making handling jam stab procedures far more difficult, stick pushers for aircraft that DID NOT deep stall, to name three) seriously degraded the safe handling of these aircraft. A stick pusher going off in the flare in strong gusty cross winds made for some interesting moments.

If my memory serves me correctly, for some time he would not even permit the use of Flap 50 for landing in the early BOAC 707. The claim was that the aircraft had a slight pitch up, before the nose pitched down, in a Flap 50 stall. This was quite true, it did, the slightest little nibble, but by that time the airframe buffet bordered on the frightening, there was no shortage of natural warning, quite apart from the fact that the stick shaker was also going crazy. But the fact remained, the nose always fell through.

I often wonder by how much we shortened the airframe lives of these aircraft in this kind of training ?? But it seemed like a good idea at the time. To my mind, given that any pilot doing this kind of type rating was already an experienced pilot, approaching stall buffet would have been enough, without doing full stalls.

AAAAAH !!, the Good Old Days. !!!

Tootle pip !!
