How do you turn off cabin altitude warning?

The cabin altitude warning horn will sound when the cabin altitude exceeds 10,000ft. It is an intermittent horn which sounds like the take-off config warning horn. It can be inhibited by pressing the ALT HORN CUTOUT button.

What causes loss of cabin pressure?

Loss of pressure in a plane can come from a hole or leak and results in loss of oxygen. Pilots then need to get the aircraft down to a safe altitude where everyone can breathe normally. Loss of pressure could be caused by a bomb and destroy the plane in the worst case scenario.

Is the 737 200 still in service?

What does CPCs mean on a 737 200?

Cabin Pressure Control System (CPCS) installed in a 737-200C. Notice the extra SMOKE CLEARANCE controls. Digital pressurisation controllers have two automatic systems (AUTO & ALTN) instead of a standby system, these alternate every flight. If the auto system fails, the standby / alternate system will automatically take over.

Why does the auto system fail on the aircraft?

The aircraft is pressurised by bleed air supplied to the packs and controlled by outflow valves. The auto system will fail if either: Cabin altitude exceeds 13,875ft CPCS; 15,800ft DCPCS. Cabin rate of climb or descent exceeds 1890 sea level fpm CPCS; 2000 sea level fpm DCPCS.

What happened to the Boeing 737 that crashed in Hawaii?

A Boeing 737 crashed near Hawaii on Friday, making it the second such incidence involving a older-gen 737 plane after a Sriwijaya Air passenger flight crashed off the coast of Indonesia, killing all 62 people aboard the 737-500.
