Is there an app to identify planes flying overhead?
A new smartphone app, while buggy for some users, may have answers.
Plane Finder AR, which debuted last week and costs $2.99, lets iPhone users point their phones at the sky and see data about flights passing overhead..
Why do high flying planes need airtight?
Humans hve difficulty in breathing at altitudes over 10,000 feet, so the cabins are pressurized. … High altitude aircraft have to be airtight so that they do not leak out all of their precious oxygen.
How fast do planes go to take off?
The speeds needed for takeoff are relative to the motion of the air (indicated airspeed). A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings. Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph).
Can airplanes stop in mid air?
No a plane doesn’t stop in midair, planes need to keep moving forward to remain in the air (unless they are VTOL capable). … VTOL means vertical takeoff and landing. It essentially means they can hover in place like a helicopter.
What causes an airplane to take off and fly?
A plane’s engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane’s weight and holds it in the sky. … The wings force the air downward and that pushes the plane upward.
Are planes checked before every flight?
The A-check is the least invasive and occurs about every 500 flying hours. The D-check is extremely thorough and occurs every six years or so. … The pilot will review the MEL and the deferred items before each flight to be aware of the maintenance state of the airplane.
What is the slowest a plane can fly?
Aeroplanes, or airplanes if you’re American, need to maintain a certain speed to allow flight. Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph).
Why do aircraft fly at 35000 feet?
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
What is the most dangerous part of a flight?
landingThe most dangerous part of any flight is the landing with nearly half of all fatal accidents occurring in the last fraction of a journey, according to US manufacturer Boeing.
How long can a plane stay in the air without engines?
Flying at a typical altitude of 36,000 feet (about seven miles), an aircraft that loses both engines will be able to travel for another 70 miles before reaching the ground.
Why do planes stop in mid air?
There is no way an airplane can stop in mid air while flying. Reasons being, if the flight is not moving forward, it would experience stall as the wings can’t find enough lift to keep the airplane up and to fly.
