Hello,
Love the A310, amazing aircraft.
Had an issue today departing CYYZ, on take-off the speed tape wasn't accelerating. Once airborne the speed tape showed a red line until passing 10,000 FT when it kicked in and started working.
First time I've come across this issue.
I've only just started flying the A310 in winter weather, might be something to do with that.
I'll test some flights and let you know.
Brgds
