Use of Oxygen Masks
Just wanted to get an idea on other airlines' SOPs for this. Our lot are going to bring in a requirement for one pilot to wear his oxy mask if the other pilot leaves the cockpit and above FL370. We have modern quick donning masks in all our aircraft and I always thought it was better not to muck around with them at all otherwise they might stop working when you need them.
Apparently this is a requirement under the new UK CARs. Any thoughts? Does anyone else do this?
