What is the resultant velocity of an airplane the normally flies 200 km per hour if it encounters a 50 km per hour tailwind?
If the airspeed is maintained at 200 km/hour with a 50 km/hour tailwind, then the speed over ground will be 250 km/hour (resultant velocity).
A plane headed due E is traveling at airspeed of 190 mph The winds are moving with constant speed in the direction 240 degrees If the ground speed of the plane is 95mph what is the speed of the winds?
To find the speed of the winds, we can use the concept of vector components. The ground speed of the plane (95 mph) is the result of the vector sum of the airspeed of the plane (190 mph) and the speed of the winds (w mph). We can find the horizontal component of the airspeed by multiplying 190 mph by the cosine of the angle between the airspeed and the ground direction (240 - 90 = 150 degrees). Thus, the speed of the winds is 70 mph.
Average speed of airplane?
too variable to answer without knowing which airplane and under what circumstances and whither ground speed or airpseed - can be anywhere from 0 to several hundred mph
N airplane flew for 6 hours against a tail wind of 25 kmhr The return trip with the same wind took 5 hours Find the speed of the airplane in still air?
Very interesting. This was obviously a Wonderland Airlines flight, on a route where a tailwindslowed them down and a headwind sped them up.But we understand what you're trying to say.6 (S - 25) = 5 (S + 25)Eliminate parentheses:6S - 150 = 5S + 125Add 150 to each side:6S = 5S + 275Subtract 5S from each side:S = 275When the wind helps, ground speed is 300, the craft covers 1,500 in 5 hours.When the wind hurts, ground speed is 250, the craft covers 1,500 in 6 hours.
An airplane flies 500 miles with the wind and 340 miles against the wind in the same length of timeIf the speed of the wind is 40 what is the speed of the airplane in still air?
Air speed or ground speed?
Dose airspeed around an airplane wing change in constant airspeed if the airplan is with headwind or tailwind?
No. 'Airspeed' is the airplane's speed relative to the air. 'Headwind' and 'tailwind' ... in fact, 'wind' in any direction ... is the speed of the air relative to the ground, which the airplane doesn't feel. So 'wind' affects only the craft's groundspeed, not its airspeed.
What is Landspeed of a airplane at take off?
This varies greatly from airplane to airplane, as well as according to ground wind conditions. Keep in mind that landspeed does not matter to an airplane nearly as much as AIRspeed. For example, your typical 4-seater single engine airplane takes off at around 60mph airspeed. Given a 20mph headwind, this aircraft could take off at 40mph GROUND speed. If you are interested in how fast the ground is wizzing by when youre looking out the window of the airliner. Most airliners take off at around 150 to 180 mph AIRspeed.
Why do airplanes take off and land against the wind?
Airplanes approach to a landing at an airspeed (relative speed of the aircraft passing through the air) recommended by the aircraft manufacturer. If an aircraft approaches too fast, it may not have enough runway to stop. If it approaches too slowly, there may not be enough air flow over the wing and the wing may stall, causing the wing to lose lift and the aircraft to descend or enter a spin. On larger aircraft, the approach airspeed varies according to the airplane weight at landing. An airplane approaching at 100 miles per hour into a 20 mile per hour headwind is traveling over the ground at only 80 miles per hour, resulting in a slower groundspeed at touchdown, requiring less runway and less braking to stop. An aircraft taking off into a 20 mile per hour headwind will reach takeoff (rotation) airspeed in a shorter distance over-the-ground than an aircraft taking off in a calm wind or tailwind. With a headwind, the aircraft will also climb at a steeper angle, when compared to its movement over the ground, helping it climb over obstacles at the end of the runway.
What indicated airspeed should be selected for a particular altitude?
Basically, there are indicated, true and ground speeds. Indicated airspeed takes air pressure differences from a sensor, corrects for pressure altitude (altitude adjusted for barometric pressure) and for temperature to determine true airspeed (speed through the ocean of air). True airspeed is adjusted for winds to get ground speed. There are many factors to consider when selecting a particular air speed. For a particular airplane, fuel efficiency generally decreases with airspeed. Increased airspeed places more demands on piloting skills. If you know all the factors, you can determine the indicated of airspeed in the cockpit. Conversely, if the factors are known, ground speed can be determined from indicated airspeed. Winds aloft, which often change with altitude, are a bigger factor for small planes than for large commercial aircraft on a schedule. For fuel efficiency reasons, when experiencing a tailwind, use a lower indicated airspeed. Conversely, when in a headwind, use a higher airspeed. Either the benefits are greater or the penalty is not as severe when wind is considered. Look at it this way. You would like to stay in a tailwind to get that free push as long as possible, so, fly slower. Different airplanes have different fuel efficiency with airspeed characteristics so the optimum airspeed would vary with the airplane, the priorities of schedule, fuel efficiency and safety as well as weather conditions. Indicated airspeed decreases with altitude, so an altitude correction must be used to get the true airspeed as well as a temperature correction (it gets colder up there). They say speed is money. How fast do you want to go? So, it is a trade off among competing factors.
How do airplanes refuel?
Airplanes refuel in the ground. Trucks carrying airplane fuel come and refuel the aircraft.Some jet aircraft have the capability of refuelling in the air.
Can an airplane be stationary in the mid air?
Airplanes can appear to be stationary to someone on the ground, but they cannot be stationary in the air.
How is speed measured in airplanes?
The speed is messured in knotsAirspeed in measured in Knots. It is generally measured by a small intake on the aircraft that measures the speed that air enters at. This measurement is know as indicated airspeed. The thing to remember is that indicated airspeed differs from ground speed as it takes into account wind speed. For example, an aircraft is flying at 110knots ground speed into a 10knot wind so it's indicated airspeed would be 120knots (110+10)
What are the classes are on an airplane?
Classes about airplanes are typically held at small airports. The airplane course is called ground school and will teach the theory of flight, rules of flight, weather and navigation.
What wind speeds can affect aircraft flying?
yes, because some wind is really powerful and can make a plane fly for ages. Yes and No. A wind blowing behind an airplane (a tailwind) will increase the plane's ground speed, and a headwind will decrease it. It can be shown that ANY wind will actually decreases an airplanes round-trip time (all other factors being equal). Some people confuse airspeed and groundspeed. Wind has NO effect on airspeed. The wind only effects groundspeed.
Indicated airspeed compared to ground speed?
Indicated airspeed compared to ground speed are different due to the movement of air (winds) around the aircraft.
Can airplanes take off with the wind?
Depends on how strong the wind is, how long the runway is, how heavily loaded the plane is etc - but generally, yes.What gets a regular airplane off the ground is how fast it's moving through the air. If the air is moving with the plane - as in a tailwind - it takes longer/more runway for the plane to reach the airspeed needed to fly.
What is the difference between true airspeed and groundspeed?
Airspeed is speed with respect to the air, i.e. speed through the air. Groundspeed is speed with respect to the ground, i.e. speed over the ground. It's the vector sum of airspeed and windspeed.
