Event Description An A319 aircraft was preparing for takeoff. During the takeoff roll, the PF initiated the rotation at around 138 kt. The aircraft responded with a high pitch rate, despite limited inputs by the PF, and the pitch angle quickly reached 14°. The flight crew continued the flight and landed safely. When back on […]

In most commercial airplanes, passengers receive oxygen through chemical oxygen systems that come in various duration options – typically 13, 15, or 22 minutes. Airlines often choose the 13 or 15-minute systems because they usually provide enough oxygen for emergency situations. In these cases, the aircraft can descend from its cruising altitude to 10,000 feet […]
