Im currently helping somebody research a university project on UK consumer law and one topic is related to smokers and long haul flights.

I have researched around and would like clarification or correction on a few opinions I have formed please.

Have any airlines gained permission to run aircon at a less efficient rate only by imposing a total smoking ban?

The air quality on smoking permitted flights was higher than non-smoking due to the aircon levels.

Could somebody give a few comparisons on the air recirc frequency in both scenarios please?

Passive smoking is a myth because the air circulation is vertical not horizontal therefore would only affect those sat in the same row??

There is a higher possibility of contracting airborne viruses on none smoking flights due to the recirc percentages??

Airlines ban smoking in order to save on maintenance costs and fuel efficiency and are also under pressure from government health watchdogs who oppose smoking??

Smoking and not being able to smoke is a huge factor in recent consequences of 'air rage'.

Thankyou in advance.

Smoking has nothing to do with an airline's decision, it's a government regulation... It has nothing to do with health and everything to do with safety (think: fire in enclosed places)

I think that some of your opinions are just as wrong as it is possible to be.

Quoting Supermatelot (Thread starter):

"Gained" permission? The knobs are in my cockpit. Whose permission do I need? The a/c controls have not changed since the plane was built.

Absolutely the opposite of my experience (other than recirc having nothing to do with it)

Quoting Supermatelot (Thread starter):

I could smell the cigarette smoke in the cockpit. I'd come home from a trip with my clothes smelling of cigarette smoke.

Sure did that. The tars in the smoke clogged the sense lines in temperature and pressurization controllers. I've seen brown streaks from the outflow valve clear to the tail of the airplane on a DC-10. Cigarette smoke was very damaging to airplanes.

If that is true then clearly we need to test passengers for this dangerous drug and deny boarding to all nicotine users. If they have no more self-discipline that that I don't want them on my airplane.


By the way, scientific research consists of finding out what the facts are and coming to conclusions based on those facts. It sounds like you are looking for quotes from us to support the conclusions you reached before beginning research.

Here is one example slamclick..

Surprisingly, alcohol is not the main cause of air rage, with drunkenness only accounting for 25% of all incidents.
Instead anxiety through delays, cramped conditions and restrictions such as banned smoking are the leading causes. http://www.flighthealth.org/air-rage.htm

Im not seeking argument,just informed clarification.No need for the hostility.

There was no hostility.

You told me that if we don't let people smoke on airplanes they might go beserk and hurt someone. As a person responsible for the safety of passengers I seek to avoid such a thing.

But it was great for finding pressurization leaks...

Thankyou for the replies anyway folks!

One more-possibly bizarre question if I may?

Could somebody please explain the physics behind the fact that if an aircraft laden with birds that was above mtow could still not take off ieven if all the birds 'flew' at the time of rotation???

Thankyou.

i'm not sure where this mis conception that airlines dont operate the air conditioning to be more economical and such has come from!

i had someone telling me the other day that most operators of the 744 only run 2 of the 3 packs to save money!

utter bs, considering when you do lose one pack or switch it off for whatever reason, the other two automatically go into high flow mode!

I may have this wrong but the birds are just transferring their weight from the sticks they were presumably perched on to the air they are flying in. Said air is still carried by the plane, thus plane carries the birds even if they fly in the inside space.

The air in a 744 weighs over a ton and the aircraft has to lift that too.

No.

Per FAA regulation 14CFR25.831:

"the ventilation system must be designed to provide each occupant with an airflow containing at least 0.55 pounds of fresh air per minute"

That's about 7.8 CFM per pax.

The first paragraph of your link seems to otherwise:

"In reality, incidences of air rage are no more common than 20yrs ago, only now there is a heightened awareness within the industry to report such cases."

Smoking was banned on airlines les than 20 years ago.

If smoking restrictions cause air-rage, then that's the sole responsibility of the person who made that choice ... has nothing to do with the fact smoking is restricted. Either don't smoke, or don't fly, if that's how you are.
