Best Answer

An airplane flying at an altitude of 2600m, approaching an airport runaway located 48km away, is descending at an angle of 3.1 degrees, rounded to the nearest tenth of a degree.

Construct a right triangle. Horizontal is 48. Verticle (opposite) is 2.6. Hypoteneuse is 48.07 by pythagorean theorem. The inverse sine of (2.6 / 48.07) is 3.1 degrees.

How many feet does an airplane fly at?

At cruising altitude most airplanes are at between 35,000 and 41,000 feet. However, to get there it has to pass all of the intervening feet between that and the altitude of the airport.


How do ailerons affect an airplanes attitude?

ailerons bank (turn) an airplane left or right. the only change in altitude. the elevators (witch are located on the rear of a plane) changes your altitude


What does climbout mean in airplanes?

Climb out is the phase of flight which begins immediately after takeoff and continues until the airplane levels off at its cruising altitude.


What energy is used to land an airplane?

3 sources of energy are used to land an airplane: # Thermal energy from the airplanes engines. # Kinetic energy from the airplanes movement through the air # Potential energy from the airplanes loss of altitude. The airplane pilot balances the airplanes flightpath and slows the plane taking into account these three energy sources sometimes using one of these to bleed off another (e.g. using the engines to provide an air brake to dissipate the remaining kinetic energy after the airplane is on the runway).


How do airplanes change altitude?

One of the main reasons is to conserve fuel. Airplanes can fly at any altitude and speed. However, airplanes generally tend to fly at high altitude to conserve fuel. This makes the plane more efficient and keeps the operating cost down. Of course, an airplane can not always fly at max altitude at every flight. It may have too much weight or the distance it travels may be too short. So there is always a trade-off as to how they will fly the route.


Why is the barometer most useful today?

Barometers are used today on airplanes to measure altitude, in airplane pitot tubes to measure airspeed, in airplane wings to detect stalls before they happen, by meteorologists to make weather predictions.


What does approaching minimums means on an airplane?

Approaching minimums is called out by an on board computer when the plane is on approach to land. It means that the pilots are approaching the minimum altitude that they can safely fly to without the runway in sight (ie, through clouds and rain etc). If they reach that minimum altitude and the runway is still not in sight the pilots must call off the landing "go around" and attempt the landing again.


In a airplane without alitmeterhow do you know when you are approaching the troposphere?

Most planes fly in the troposphere anyway but without an altimeter you could take temperature readings as those vary by altitude.


Why at high altitude the amount of oxygen decreases due to increase of carbon dioxide?

Most airplanes fly at high altitude because it is faster and safer as long as the cabin is pressurized. There is less clouds and turbulence. The airplane uses less fuel.
