737 Takes Off Without Cabin Pressure!

Tue Jun 28, 2005 10:57 pm

Passengers on a Canjet flight YYZ-YHZ got an awful experience when their Canjet 737 took off without pressurization in the cabin!!

Has this happened before?

Per the article:

"The head of CanJet, Ken Rowe, said flying without pressure in the cabin is an irritant, not a saftey concern."

Only if you stay under 8000 feet.

i remember this from the 737 FOM:

"An unpressurized 737 flying during the day with 100 passengers will produce a cabin temperature of over 30 degrees Celcius flying at an altitude no greater than 8000 feet"

10,000 is the limit in the US and its not that big of a deal. The cabin altitude is (oh my!) 8,000 feet in some aircraft in cruise.

What would you expect an airline to do if the AC packs are inop. Do a short flight low to somewhere it can get fixed, or cancel a bunch of flights, inconveniencing hundreds of passengers, just to pay through the nose so some outside MX outfit can fix it.

I go with the first option, but then again, thats just me.  Smile

Do the short flight once there are no high terrain problems in the area I suppose.

Secondly, I'd prefer to think they would cancel the flight and get it fixed. I doubt it's legal to fly with the oxygen packs inop? I doubt it.

It depends on what the MEL states for that aircraft, which of course would be approved by FAA or equivilent. I've worked a flight in a non-pressurized aircraft, although this was a SAAB340

You're thinking of part 91 flight, and it's 12,500 feet. Under part 121, which this airplane would be flying under if it were in the US, the oxygen rules start at 10,000 feet.

Quite legal, few extra rules to abide by, but certainly not illegal.

As long as they stick to the rules and to not fly higher than 10'000ft or whatever the limit is in Canada it is absolutely legal, unless the MEL says somewhat different. I do not fly the 737 and for sure it is not first choice to do a flight, carrying paying passengers without pressurization but basically it should work. Operators flying the Shorts, the Twin Otters or DC-3's are flying all day long without pressurization  Wink

Oh brother... we take off unpressurized all the time. Standard practice on the avro is to take off with the APU running and supplying the air source. However if the APU is deferred our SOP is to take off unpressurized with no air and once airborne in the after takeoff check we bring the engine air on to pressurize. Other situations are like as mentioned above... if packs are deferred one can fly at 10,000 unpressurized. It's not uncommon what WestJet did. The media acts as if people that live in high altitude cities or who moutain climb bring portable pressurization bubbles with them!!

They'd be horrified, and counter that every aircraft had to be 100% perfect before it departed.

Of course, forcing one of them to keep their personal car in the garage (on a clear day) because the windshield wipers happened to be inop would be a totally unacceptable concept...  Wink

Yes, very true!

Is it common to take off on an Airbus/Boeing with the cabin unpressurised? I know if there is depressurisation during flight, the crew must descent to 10000/12000 ft, at which altitude passenger should be able to breath normally, so if for some reason a flight is going to be short and below this altitude, would it be common practice to not pressurise.

Exuse my question if they seem ignorant, which they may very well be, it's just I was recently working on a large document on depressurisation (I'm a translator) so this is quite interesting!

Would you really like to try and open this door in flight? Or let me ask you, would you try it if the cabin was pressurized?
Sure, due to a working pressurization it is pretty impossible to open them in flight, but I still would not go and try it. There are several things in aviation they do not need to be tried out at any prize. I remember a Crossair Crew in ZRH, trying if the gear can be retracted by pushing an override button. It was not really there day, the SAAB 340 ended o it's belly.....  Wink
By the way, I wouldn't try if the Thrust Reversers really don't open or not in flight either...

...I got this, but I think you don't have to worry about. Number one reason is that if there was a danger, there would be a certification issue, as on a non pressurized plane they basically can be opened all time long. Second reason, if you imagine the cumulation of incidents you need to face, to have a situation with a drunken guy trying to open the door and just this day, the pressurization is not working.... so, probability is that low that it is negliable.
Sure, the imagination to fall out a plane at 10'000ft is scary, but I think it's still better than to fall out of a train going 100 miles an hour. Both will kill you, you just get a better view, falling out of the plane Big grin

I once worked a flight where I noticed my ears were popping excessively as we ascended past 10,000'. Needless to say, I called the cockpit to find out what was going on. They told me they were having problems with the pressurization and they were doing some manual tests. If that didn't work we would return to our departure city. Sure enough about 1 minute later, we turned around and headed back.

Everything was OK when we left, but things happen. I suspect maybe what happened in Nova Scotia was similar, but we all know how the media sometimes "twists" facts or contexts.

I door can be opened when there is zero pressure differential. The fool opening the door would still have to contend with the slipstream. I don't think are are very many people that can swing a door open when the aircraft is going 250 knots (the limit under 10000ft).

No aircraft with doors that open into the cabin, and stay in, like the B767, MD11, etc....The door certainly can open. Totally electric doors (MD11) may be wired through the ground buss which would keep them from opening, but I can't think of any mechanism that would keep a B767 door from opening.

It really depends on the aircraft. Most turbine aircraft are pressurized, so for efficiency reasons, flying above 10K is usually the best option. However, this is more common when flying in an aircraft with reciprocating engines.

Unless the flight is going to be very short, OAK-SFO, I really wouldn't see a situation where you wouldn't pressurize (unless the packs are INOP). Even on such a short flight, it's more comfortable for the passengers, especially if you can maintain the pressure at sea level.

The people in the back are paying the bills in the end, so you try to keep them as happy as possible.

I have flown a C182RG at 12,500 to take advantage of a tail wind. I did get a nice headache out of it but it was perfectly legal.

Off the original topic... but beleive it or not it has been tried on passenger flights - For example, the Alitalia DC8 which crashed on landing at JFK in Sept. 1970. Apparently the pilot came through the clouds on approach to discover he was high & fast, and rather than go around he used reverse thrust...

He couldn't recover when he fell below ther glideslope. If I recall the NTSB report, it referred to the fact that the practice was not unknown on DC 8's... See the summary at:

Please allow me as well to deviate once more from the topic:
As far as my senior colleagues who had the privilege to fly the DC-8 told me, was a McDonnell Douglas procedure to apply reverse on the two inner engines in flight.
The Alitalia one was a result of a crew, applying on the inners and still being high and fast..... and going for all four in reverse
There was also a Swissair DC-9-51 on approach for Malaga Spain. It was a future Captain in his supervision. The guy came from the DC-8 where he served as a F/O. Being used to apply reverse in flight, he did it on the DC-9. He was lucky, because he lost both sets of reversers, what actually prevented them from a crash. His supervision was also terminated that day, he remained F/O for the rest of his carrier.

8000 feet is the cabin altitude throughout flight. so there would be no differing effects up to that level, unless air conditioning was down fully.

anything above 8000 would feel different however

Quoting ACdreamliner (Reply 40):

the pressure changes relative with the altitude. If you take off at a Sea Level the cabin altitude is sea level. You can set the "climb rate" of the cabin so if you are going to only 28,000 ft you could probably maintain a 4,000 ft cabin for instance so you would set the cabin altitude for 650 ft/min, etc.

Most airliners have an automatic setting to optimize cabin altitude changes.

As you can down, saem thing, the cabin pressure would "descend" with the aircraft.

I have been at 20,000 ft with a sea level cabin in a Lear 35 before, your ears never pop!

RE: 737 Takes Off Without Cabin Pressure!

Wed Jun 29, 2005 6:24 am

My dad flew in an AA 727 DFW-IAH unpressurized in 2001. He said they flew at 8000 feet.
Firings, if well done, are good for employee morale.

Well, CanJet is a no-frills low-cost carrier which means that everthing else beside your seat and your luggage is an added cost.



Quoting PIA777 (Reply 29):
The landings were terrible both times.

Maybe you should've paid for a good landing! Big grin

YYZ to YHZ is a pretty long haul at low altitude, must've cost them a lot more on fuel. Cheaper than the alternative I suppose.
As far as pressurization goes, I doubt it's as painful as flying unmedicated with a sinus cold- I made that mistake once when I was young & stupid (not young anymore). Maybe the passengers just wanted a thrill ride in the weeds? "Ow, my ears, go lower!"
Can you hear me now?

I think the title of the post is misleading... all aircraft takeoff un-pressurized.

They don't pressurize until they're off the ground.  Wink

Sorry, I have to disagree with your statement. I know, you are joking with the topics in regard of technical details but would like to clarify some aspects of the pressurization and environmental system of an aircraft anyhow:

The outflow valves of the cabin are wired on the squad switches. This means, as soon as you get weight on the wheels (landing) those valves are going to open and let the cabin depressuirze. The cabin should have bee brought already to field elevation, otherwise you will feel it in your ears. So it is most over a prevention.

This does not mean that you also take of unpressurized: The pressurization controller is wired to several systems. So when the engines are accelerated into take off mode the outflow valves will close and the cabin will pressurize 300 ft below field elevation the aircraft still on ground. The aircraft will take off and climb, the cabin will climb as well until it reaches it's preset value. The pressurization schedule is set like this to make it as smooth as possible and to avoid any brisk pressure changes.

This may vary a little from aircraft to aircraft but the system is most of the time the same.

Quoting Gigneil (Reply 26):

I recall a smoke filled 747 descending to 10,000, putting the safety belt demonstrator across a door, and cracking it to vent smoke.

United, perhaps?

And that wasn't a one time thing. That is a standard procedure that all flight attendants learn when they are getting trained on a 747.

Quoting ACdreamliner (Reply 40):
8000 feet is the cabin altitude throughout flight

Depending on the airline and aircraft involved, cabin altitude at cruise can commonly vary between 5600 and 7400. During normal operations most never go all the way to 8000.

Please excuse me if I am being ignorant, but I asume this is one of CanJet's 737-200s, not the newer 737-500s. Can someone confirm this?

This would have been a 735 in all likelihood. C6 only has 2 732s left.

As is proven in the above article, when a flight is delayed, especially due to mechanical reasons, there's often a couple of ring leaders on the flight who try to grab the spotlight and all the headlines. Almost always it involves people with zero knowledge as to how an aircraft / airline functions.

The pax should of course receive a bit of compensation for the delay, but the weather is not the airline's problem...even though so many passengers think the airlines magically control the weather...the weather's bad, tough luck.
