TWY must intersect the runway south of the GP antenna and holding point no closer than current A1 & B1 distance from RWY centre line, 105 metres for a Precision CAT 1 runway, if my aged brain is still working. Could be angled to intersect slightly less than 90 degrees, just about where I remember most Q400s ended up on their landing roll, unless the training captain (if he is still SOU based) was PF (no pun intended), in which case a stop at Bravo was common place.
