Pity the poor skipper if the 777 is fitted with those awful "Eros" O2 masks.
Doubtless a lot of heavy breathing and if using one, (s)he would deafen and distract themselves with the racket every time a breath is taken.
There must be some fume events in real aircraft where comms, both internal and with external agencies, have been degraded and corrupted, yet the aircraft manufacturers and the certifying authorities insist on their fitment.
Bad enough in the simulator, but trying to switch the damn things off whilst inhaling in the real event, in an attempt to make comms clearer, must make one curse their designers and manufacturers.
The recent sad losses of freighters from inflight fires may have been adversely affected by these masks-does anyone know if the subsequent accident reports mentioned the disgraceful audio quality from inhalation noise?
But then it would be too expensive to change them for a properly designed off-the-peg O2 mask/audio combo, such as are fitted to most military aircraft.
Back yet again to "The Tombstone Imperative"!
