Again, not dash so it's all 3rd hand.
Apparantly, with the dash having such a long main landing gear leg, it has to be extremely stiff (to prevent fatigue cracks of the mounts etc). This, coupled with the long fuselage, which limits the amount of flare the PF can use. This all adds up to a "positive" arrival. Apparantly most guys on the fleet don't try to "grease it on" any more, just accepting that it's damn near impossible to get a nice landing out of it.
As far as prop/jet ops, I dare say for 90% of UK/Northern European ops, CatII is more than sufficient. Most guys I fly with can count on one hand the number of times they have diverted/scrubbed due to weather. Small comfort I know.
CM thanks for the confirmation. My ops manuals were 200 miles away when I wrote that, and I hate to knowingly give duff info.
