When the cabin oxygen masks will automatically drop down?
Oxygen masks release whenever there's a drop in cabin pressure. Sometimes the flight crew might initiate the release. However, it usually triggers automatically when the cabin altitude gets to 14,000 feet.

When the pressure drops in the cabin, oxygen masks will fall. Once you affix the mask to your face, you can breathe normally and a continuous supply of air begins to flow.
Cabin Oxygen SystemEach container has an electrical latching mechanism that opens automatically to allow the masks to drop, if the cabin pressure altitude exceeds 14,000 ft (+250, -750 ft). Chemical generators produce the oxygen.
When a plane has pressurization issues, pilots typically try to get below 10,000 feet as quickly and safely as possible. At higher altitudes, the air is thinner, which is why oxygen masks deploy in the event of a loss of cabin pressure.
When and How Are Oxygen Masks Released? Oxygen masks release whenever there's a drop in cabin pressure. Sometimes the flight crew might initiate the release. However, it usually triggers automatically when the cabin altitude gets to 14,000 feet.
Current FAA regulations require that the cabin pressure altitude on transport category airplanes remain at or below 8,000 feet in normal operating conditions, and that supplemental oxygen be automatically presented to passengers before the cabin pressure altitude reaches 15,000 feet.
When the cabin altitude rises above 14 000 feet, the oxygen masks stored above the passenger seats, in the lavatories, galleys, and crew stations will deploy automatically. The flight crew may also manually deploy the oxygen mask system.
When you fly on an airplane, the flight attendant instructs you to “put your oxygen mask on first,” before helping others. Why is this an important rule for ensuring survival? Because if you run out of oxygen yourself, you can't help anyone else with their oxygen mask.
Most aircraft cabins are pressurized to an altitude of 8,000 feet, called cabin altitude. Aircraft pilots have access to the mode controls of a cabin pressure control system and – if needed – can command the cabin to depressurize.
For Part 91 General Aviation operations the required flight crew must use supplemental oxygen for any portion of the flight that exceeds 30 minutes above a cabin pressure altitude of 12,500 feet mean sea level (MSL) up to and including 14,000 feet (MSL).
FAA encourages oxygen use for pilots on flights operating above 10,000 feet mean sea level (MSL). The regulations for flying above an altitude of 12,500 up to and including 14,000 are fairly simple. At that altitude, all crew must use supplemental oxygen continuously if the flight is over thirty minutes.
