What about your airspeed alive check on the take off roll?
Yes, of course I check it then. But at Sleap, I have to taxi a long way from where the aircraft lives to get fuel etc. So if it's safe, I try to check it then too. Why not, if I can? Then if anything might be wrong, maybe I have advance warning, before I even consider taking off. It's just me, and just a belt and braces approach. I've only been that extra-careful since we had the spider in the pitot tube.
