Why the Boeing 737-600, 737-700, and 737-800?
- The 737-600/-700/-800/-900 team worked hard from the beginning of the airplane’s development to keep maintenance costs as low as feasible and to provide airlines with the most competitive operating expenses possible.

Where is the crew oxygen bottle shutoff valve in the cockpit?
The crew system shutdown valve is a manually controlled valve that is responsible for shutting down the oxygen pressure in the flight crew oxygen system. The valve is positioned in the control cabin, on the forward sidewall of the engineers panel, at the front end of the panel. The pressure-reducing regulator is placed next to the oxygen cylinder for convenient access.
At what cabin altitude is the passenger oxygen system automatically activated?
The compartments containing the oxygen masks will automatically open, either above or in front of the passenger and crew seats, if cabin pressurization is lost while the aircraft is flying at an altitude greater than 4.267 m (14,000 feet). The oxygen masks will then drop down in front of the passenger on most pressurized aircraft.
How long approximately will the passenger oxygen last once activated?
Answer: The oxygen generators on most commercial airplanes have a lifespan of 10 to 14 minutes. That is more than enough time to drop below 10,000 feet, which is the lowest elevation above the landscape at the time of writing. Airlines may descend at high speeds, which implies that the requirement for supplementary oxygen is only required for a short period of time.
How do aircraft oxygen systems work?
Fixed systems obtain their oxygen supply from a cylinder of pressurized gaseous oxygen stored at a remote location. This can either be a specialized cylinder or it might be the same cylinder that is used to provide the flight deck passengers with oxygen. A single regulator distributes oxygen from the cylinder to the passenger compartment using an oxygen manifold.
How many oxygen cylinder bottle does b737 200 have?
On Boeing 737-1/200 aircraft, passenger oxygen is provided by two oxygen bottles located in the front hold.
How many emergency exits are there on a Boeing 737 800?
A total of eight emergency exits are available on the plane: two in front of the First Class cabin (one on each side), four in the center of the Main Cabin between rows 16 and 17 (two on each side), and two in the back of the plane (one on each side).
How much oxygen is in an airplane mask?
With the mask, the concentration climbs to 100 percent, necessitating just a small amount of pressure to achieve absorption. Contrary to popular belief, the oxygen utilized by passengers in emergencies does not originate from concealed canisters in the plane, but rather from a chemical process within the plane.
What is the oxygen level in an airplane?
Air travel is stressful because of the low oxygen level in the airplane cabin, which is a significant stressor. When cabin pressures are similar to elevations ranging from 6000 to 8000 feet above sea level, it is possible that just 15 percent of the oxygen found at sea level is present in an airplane cabin, rather than the 21 percent found at sea level.
What is in airplane oxygen masks?
If the cabin pressure falls below a certain level, either the flight crew or an automated trigger will deactivate the masks. You’re releasing those overhead chemicals — often sodium perchlorate and an iron oxide — and allowing them to mix together when you take the mask down. The chemical process, often known as “burning,” produces oxygen, which is then delivered to you.
Why do you need oxygen masks on airplanes?
Oxygen masks are truly intended to protect your health and safety. Because the air at high altitudes is thin and the oxygen levels are low, airplanes have sophisticated mechanisms in place to maintain cabin pressure at a level that is similar to a height of around 5,000-8,000 feet.
What do flight attendants say about oxygen masks?
In order to aid others when flying on an airline, the flight attendant urges you to “first put your oxygen mask on.” What is the significance of this rule in terms of guaranteeing survival? Because if you run out of oxygen, you won’t be able to assist anybody else with their oxygen mask if they do as well.
Do fighter pilots have to wear oxygen masks the entire time they fly or can they take off their masks?
Any aircraft equipped with a static pressurization system must maintain a cabin/cockpit pressure of 8000ft or less, regardless of the height at which it is flying. This eliminates the need for all occupants, including the flight crew, to wear a mask during the trip.
Do pilots breathe pure oxygen?
By flying up into thin air at high altitudes, pilots can feel the same physical sensations that they do on the ground. U-2 pilots prepare for their flights by breathing pure oxygen for an hour before taking to the skies and wearing a pressurized spacesuit. The use of pre-breathing oxygen aids in the removal of nitrogen from their bodies.
What are the requirements for supplemental oxygen for the crew of pressurized aircraft?
Provision of more oxygen is required:
- From sea level to 12,500 feet, there is no need for oxygen. If the needed crew spends more than 30 minutes at this height, they must descend to 12,501′ to 14,000′. 14,001′ to 15,000′ – This altitude is required to be given and used by the necessary flight crew. Every resident must have access to the range of 15,001′ to 25,000′.
What is the most common oxygen system on small aircraft?
Steel cylinders and composite cylinders are the two most frequent types of cylinders found in aviation gaseous oxygen systems. Steel cylinders may be classified into two categories: 3AA cylinders and 3HT cylinders. 3AA cylinders are the most common. DOT 3AA 1800 (3AA) cylinders are common industrial-size steel cylinders that are usually seen in older airplanes, but may also be found in other aircraft.
