Do airlines have backup planes?

Answer: Some of the larger airplanes (e.g. Airbus A340 and A380, and the Boeing 747-8) have cameras to help assist the pilots on taxiways and at gates. Smaller airplanes (e.g. B737 and A320) do not need them as the flight crew can see the wingtips.

Why are planes suddenly flying over my house?

Why am I suddenly getting more aircraft going over my house than previously? Aircraft take off and land into the wind, or with minimal tail wind. As a result, the wind direction dictates the selection of runway(s) in use at any time. This in turn determines which flight paths are used.

Why don't planes have built in parachutes?

This is because the air is so low on oxygen at any higher altitude, the skydivers would need supplemental oxygen strapped on in tanks to avoid passing out from hypoxia. Given the cruising altitude of a commercial plane, passengers would require an oxygen tank, mask and regulator.

What happens if there is an emergency on a plane?

If it's an emergency, you call an ambulance and within minutes you'll have professional help at your door. If it's really serious, they can whisk you off to the nearest hospital. ... All of a sudden, that ambulance on the end of a 911 call seems a millions miles away.

Do planes have redundancy?

In the modern aircraft the majority of systems are computer controlled; therefore a problem with one of the key components could cause a total system failure. In many cases, safety critical equipment is in triplicate (also known as triple modular redundancy) this allows a majority voting system to be used. ...

Can a plane land without landing gear?

A belly landing or gear-up landing occurs when an aircraft lands without its landing gear fully extended and uses its underside, or belly, as its primary landing device. ... During a belly landing, there is normally extensive damage to the airplane.

Why are planes flying so low now?

Why are the airplanes flying so low over my house? Aircraft are limited in the direction they fly because they must land into the wind. Therefore, the flexibility of air traffic is dependant on the wind patterns of the day or, even, the hour, as winds can change rapidly.

Why do planes fly low at night?

FAA recommends general aviation aircraft to stay below 5,000 ft at night time. ... But one of my friends claimed the reason why we are supposed to fly at a lower altitude to prevent from hypoxia is that at night there is higher pressure near the ground which makes fewer air molecules at high altitude at night than daytime.

How Low Can planes fly over my house?

The regulations usually require that pilots fly no lower than 1000 feet over built-up areas, or 500 feet over any other area, and we may investigate low flying incidents. ... You can report a low-flying aircraft by completing a report a low flying aircraft form, along with any information to support your complaint.

Is it illegal to bring a parachute on a plane?

Parachutes are allowed by TSA on American carriers but are subject to inspection and you must open if requested. It must meet airline carry-on requirements. Skydivers do travel with their equipment, usually as checked baggage.

Can you jump out of a crashing plane?

Originally Answered: Could I survive a plane crash into water by jumping out just before it crashed? Almost certainly not. Even the very slowest aircraft usually have to travel in excess of 40 knots just to stay airborne, even in a descent.

Can you parachute from a helicopter?

Helicopter pilots do not wear parachutes but there are a few helicopters with parachute rescue systems. Most helicopters operate low-level and to safely exit a helicopter and parachute away would require altitude and a safe route away from the main rotor system.
