On the topic of Doc 8168 procedure design...
Yes - 280 KIAS will get you well outside the protected airspace boundary if you time the turn. If you fly a DME-limited turn and the speed is reduced before the inbound turn is commenced, you have violated the word & letter of 8168, but have not jeopardised your obstacle clearance. Either way, the intended outbound speed should have been covered in the brief, and 280 should have triggered a challenge, no matter what.
The "once-around -the-hold"-issue is somewhat more clear-cut. The 8168-wording as cited (especially the bold-face sentences) are at best ambigous. But this does not subtract from the fact that if you do things the way BOAC suggest, you're a lot safer than if you just parallel-tracked outside the inbound radial. If you intercept that radial outbound - you know where you are (but are complying with 8168 word & letter). If you just head outbound on a parallel track (especially non-EFIS A/C) - you & 8168 are best buddies, but your position awareness could be better. I know which one I prefer (and fly)...
Further, if the speed had been correct (racetrack vs. hold - not hold-vs.-280
), you are established on the LOC & are configured for the approach & everybody has been briefed & is ready - then why not shoot the approach straight in? You are in the right piece of sky, tracking the right way, on the right config, speed & SA - so why not do it? I have only come across UK F/Os asking why we did not go once more around the hold, no other EU crew thought it a problem. Is it a particular training habit @ UK FTO's or are the rest of us missing the point?
