A loud bang and a shudder on the runway might indicate a blown tyre, a potentially serious problem. A sound like an engine backfiring, while flying relatively close to the ground, could suggest a bird strike.

3 dings means something or nothing at all. It depends on the airline's procedure. At one airline, it means there is such an urgent emergency that the captain has no time to discuss it with the flight attendants. At another airline it means the flight attendants are now safe to get up and walk around the plane.
Cimato first explains that if you hear a high-to-low chime, it means one flight attendant is signaling another — or that the flight deck is trying to reach them. Meanwhile, one single tone means that a passenger is trying to get help from a flight attendant.
Takeoff: Two quick, loud thumps from under the plane, and a repeated whooshing noise that sounds like a spinning propeller. The whooshing noise is air from the engines (the air used for the cooling and heating system) changing as the RPM of the engine increases.
Airplane noise can be very annoying, especially if you live or work near an airport, and you should know that experiencing that noise constantly can be bad for your health. Some of the negative side effects include high blood pressure, increased risk of stroke and increased risk of heart attack.
All airplanes will be exposed to drag during flight. They must overcome this aerodynamic force to achieve and maintain lift. Otherwise, airplanes would essentially fall out of the sky. Air brakes are control surfaces that increase drag so that airplanes slow down during flight.
A discrete transponder code (often called a squawk code) is assigned by air traffic controllers to identify an aircraft uniquely in a flight information region (FIR). This allows easy identification of aircraft on radar. Codes are made of four octal digits; the dials on a transponder read from zero to seven, inclusive.
When an aircraft experiences turbulence, the plane can drop or change altitude suddenly. This is why pilots always caution passengers to buckle up and stay seated when they are experiencing flight turbulence. The sudden movements put passengers at risk.
The idea is to get as much altitude as possible, as close to the airport as possible. So you have a relatively steep initial climb, followed by a reduction of climb angle to cruise climb and a power reduction.
As the tail comes up, a force is applied to the top of the propeller. And since the propeller is spinning clockwise, that force is felt 90 degrees to the right. That forward-moving force, on the right side of the propeller, creates a yawing motion to the left.
Jet airliners, on the inside, are loudest in the last few rows at the rear. Outside, right at the engine exhausts, but you're in serious danger from the engine if you're anywhere near that. Most of the noise goes backwards away from the plane.
Yes, Bose noise canceling earbuds are suitable for use on airplanes and are designed to reduce ambient noise, such as the sound of the plane's engines.
When deciding either window or aisle seat, the window is found to be the loudest on the plane. While aisle seats are quieter, do note there's also a higher chance that other passengers from the inner seats might interrupt you if they need to go to the washroom.
Fifty years ago, the federal government banned all civilian supersonic flights over land. The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won't startle the public below or concern them about potential property damage.
