O2 masks
"The Times said the Captain was required by standard procedures to wear an oxygen mask for the remainder of the flight becuase he was on his own - is this a normal SOP on longhaul ops because it is not a requirement in my company."
This is a very old rule that was changed years ago. I am sure the 767 Capt did not put on his mask. The statement in the paper came from another speculator. The only requirement to wear a mask when you are alone in the cockpit is when you are above FL410. Other than that, the mask has to be readily available which they are with quick doning masks in all airliners."
Could be the Times read the FAA rules - 121.333 says if only one pilot at controls above FL250 he has use the Oxygen mask. The FAA was going to change that a year or two ago but kept the rule in the end.
