maple_syrup_82 Posted November 20, 2022 Share Posted November 20, 2022 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.

Alexair Posted November 20, 2022 Share Posted November 20, 2022 (edited) Happened to me as well depsarting Rovaniemi EFRO. It is ice clogged pitot tubes. Shouldn't happened when all pitot heaters ON. It's a bug and I believe they are investigating. One thing interesting though, on my Honeycomb throttle quadrant I have always the ANTI-ICE warning ON (which is linked to pitot heat). Even with all pitot heaters ON in A310. However, if I'm switching my physical switch on my quadrant to turn pitot heater ON on my Honeycomb, the warning light extinguish and no more pitot icing. That make me think that pitot heater is not properly link to the switches in the panel. Edited November 20, 2022 by Alexair Link to comment Share on other sites More sharing options...

toddl Posted November 20, 2022 Share Posted November 20, 2022 I had the same issue flying out of CYYZ today as well. Speed tape and gauge non-functioning until higher altitude. Link to comment Share on other sites More sharing options...
maple_syrup_82 Posted November 20, 2022 Author Share Posted November 20, 2022 Hello, After further testing and using developer mode I was able to see when icing hits 0.7 and higher the speed tape wouldn’t accelerate on takeoff, so seems this is a pitot heat issue.

BottleCap Posted January 24 Share Posted January 24 Was this ever fixed? For the last few weeks I'm not able to fly in the northern hemisphere because of this. A310 was working fine all summer long and still works fine in the southern hemisphere. Link to comment Share on other sites More sharing options...
