Air Data Sensor Heats Default to ON. Should default to OFF/IDLE

[Joshua Green]

On all cold and dark starts, these buttons start latched. They should not. 

Pilot and FO Window heats, even when unlatched, do NOT turn off. They should.

Hi, do you have a source for this?

In varying company procedures aircraft switches are usually left latched and then unlatched, pressed and then latched. Let me know what you find and I will be happy to pass this along to the team. Thank you.

In regards to the air data sensor heats, I'm afraid I don't understand your first sentence: If they are left latched after landing (and therefore latched for the next flight), under what circumstances would they ever be unlatched? When do the procedures you're referencing indicate that they should be unlatched?  The provided checklist in the inibuilds manual suggests they should be unlatched after landing. That implies that they would remain that way until the next flight, and that they would be latched again during perhaps pushback or at the holding point. 

In regards to the Pilot and FO window heats, the buttons simply don't seem to function. Latched or unlatched, the "idle" light does not illuminate.

Hi, sorry the earlier was a mis-statement on my part, it appears I had misread both our manual as well as another piece of material I looked up earlier, a good sign that I needed to rest my eyes. You are indeed correct that the panel state contradicts the manual, I'll ask the team about it. As for the second issue regarding the Window Heats not illuminating. This is a known issue.

Sorry for the confusion and thanks for bringing this issue forward 🙂
