How do pilots know what altitude to fly?

Answer: The flight operator files a requested altitude, usually done by the flight dispatcher, based on performance and economics. Air traffic control reviews the flight plan, checking for conflicts. They issue the cruising altitude based on the requested flight plan and other traffic.

Because the Earth is a three-dimensional sphere and not merely a two-dimensional flat, East-West surface. Because of this spherical shape, often times the shortest distance is flying more north and south, up over the Northern latitudes and the North Pole, rather than flying east/west over the Pacific.

The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.

Planes have headlights so that pilots can see what is in front of them. Unfortunately, they are only effective during takeoffs and landings. Even with the slight illumination offered by the headlights, only darkness is visible when looking out the front window of a cockpit.

This happens especially on longer flights where the aircraft initially has many tons of fuel onboard that need to be lifted. During the flight, as the fuel is burned, the aircraft will be able to climb to a higher altitude.

When a plane lands the pilot has to quickly do two things to keep the plane going straight: get ALL the wheels tight on the ground, and use the rudder and to steer the plane straight. If there is a strong crosswind, it can be quite tricky to do this in a small plane.

The anemometer, the instrument for measuring speed in aeroplanes. Pilots have to promptly know the speed at which they are moving in the mass of air that surrounds the aeroplane and the anemometer is responsible for measuring it. The anemometer, as it is known today, was designed in 1926 by John Patterson.

Yes, and no. Aircraft normally fly at an optimal indicated airspeed until they reach their optimal climb/cruise Mach. This transition from airspeed to Mach normally occurs in a transition zone of around 27000 - 30000 ft.

Knowing the amount of altitude to descend and the vertical speed of the descent, the proper time to begin the descent can be determined. Most modern airplanes do these calculations for the pilot and provide him/her with a top of descent point in the flight management computer.

Airline pilots take turns using the bathroom nearest the cockpit during a flight. There are no bathrooms installed in the cockpit. For airplanes with a single pilot, diapers, catheters, or collection devices are used if they are unable to land to use the airport bathroom.

This really depends on the type of aircraft and the seating position of the pilot. In smaller aircraft, you will have a good view of the area around you, depending on the canopy. In larger aircraft, the instrument panel and cockpit design can restrict your outside view a bit more.

While pilots can't actually see turbulence, they often know what is coming up, thanks to reports from other planes, weather reports, and radar equipment. However, clear air turbulence (severe turbulence occurring in cloudless areas) can sometimes catch pilots off guard.

The most common reason is that there are no airstrips or airports on many of the small islands, so if a plane had to make an emergency landing, it would be difficult to find a place to land. Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.

Aircraft with fixed wings cannot stand still in the air, unless we are talking about VTOL (Vertical Take Off and Landing) aircraft. Lift is created by air flowing around the wing. Too little forward speed, and the wing will stall (loose lift).
