How many oxygen kits does an aircraft carry under normal circumstances?

I think it is approx. 1 per 50 pax or so. About like F/A requirements. That's pax seats not actual pax on board.

Thanks.

Are we talking walk around oxygen bottles? They are really for crew. Thinking of the A300 probably about right. We had 361 pax seats. I thought that with most aircraft you could plug a pax into the drop down system. Wrong?

Anyway presumably pressurised to 8,000' so no shortage of 'oxygen'. Could have had a a/c pack turned off to save on fuel and they were not getting the air circulation. Less than a certain number of pax with Monarch SOPs said turn one off. Cabin crew complained like hell about feeling faint. I refused to do so. We felt faint on a 777 as pax once which was a low pax load. I asked the crew to request the Capt to turn back on the second pack. I think he did.

It was Ryanair after all - had the pax paid for air?

Perhaps the ones affected had lost their tokens or didn't have the right change for the dispenser.

1 per 50 sounds right

Some have a spare socket every few rows and you can connect there after a dropout. Pax O2 is not active until then. Most being O2 generators these days.
There is a little button on the hat rack to locate same. This depends on suitable mask and pipe availability.
The Senior Cabin Staff member on duty (SM) advises portable bottles for crew use but can be used if one of the cattle is dying.

In days of yore there would be replenishable bottle for drivers and a further two or three for a pax system. For me last seen 727, maybe 737-200 and A300B4.

No RyanAir aircraft has any way of 'plugging anything in' to the drop-down system. It is completely separate and chemically generated as Wodrick says. There are 4 drop-down masks at each seat row. The 'bottles' referred to are the portable crew bottles normally stored in hat racks at the front and the back.

The "walk-around" bottles also have a port to supply O2 for medical emergencies.

The Hi - Lo outlets (44 - 21psi) would bewilder me Phlyer on SEP renewals. Which one would I attach the oronasal to for say a heart attack or just a queezy post decomp? Also 500psi min to be left for walk around post decompression use vs the 300 limit for bottle protection were another two I’d get mixed up with. I just left it to the girls.

There are 4 drop-down masks at each seat row.

Why 4? Surely it should be 6 for non-bulkhead rows and more for bulkhead rows for BSCT pax.

I'm frankly surprised Ryanair do not offer coin-in-the-slot O2 dispensers such as can be found in Japan.

- kids on laps/passing c/crew/broken masks? Ah! I said 'seat row' = 3 seats ie 8 for your 'seat row'.

Yep :

The total number of oxygen dispensing units shall exceed the number of passenger and cabin crew seats by at least 10 per cent.

No I wasn’t involved, but I know a man that was

Stand 331 is pretty tight at the best of times and rarely used for 747 ops.

Hmm. Obviously not a glance to the left! Far too old to operate an aircraft

Ground staff on the ball too!

Taxying into a - previously unfamiliar to us - new style self-parking stand at Bombay one night, line up ahead by keeping a light visible through a slot in front of the box in which it was housed. All OK but asked the Co_pilot where the stop signal was ? Looked out to the left, nothing, looked out to right - Christ ! we've just passed it, i.e. a similar light to be lined up placed at right angles to our direction. Stamped on the brakes and stopped, as it happened a couple of inches from driving the number two engine into the passenger gangway. No contact, no damage. First person on the flight deck was a turban wearing local, who looked out at the forward direction guidance light, and the right angled stop light, and said, with attendant head wagging " The lights are on, it was not our fault". Maybe so, I said, but there are about 6 of your staff stood down there watching us come in, couldn't one of them have crossed his arms across his head to indicate that we should stop ? No, he replied, we are not trained aircraft marshallers. They would have idly stood by and watched me drive 3k tons for aeroplane into their boarding gate rather than attempt to stop us.

No comment less I'm deemed racist ?

.....we are not trained aircraft marshallers.

Would it have made any difference, in that part of the world? Pulling off stand in Nairobi. Our principle pax had transfered directly to us from a Kenyan Air Force aircraft, poor chap. The pilot had parked along side us and unseen from the flight deck within our wing (swept) span. The local NR marshaller was happily marshaling us forward oblivious to the impending collision. I glanced down at the Air Attache to wave goodbye to see that his salute had changed into a stop signal. Guess who I responded to
