Ground speed is the speed the aircraft has compared to the ground. This is usually different from air speed, which is the aircraft's speed compared to the surrounding air.
Thus an aircraft with 400 kph air speed and 50 kph headwind has a ground speed of 350 kph.
For fun: with light aircraft with very low stall speeds it's possible to fly backwards (compared to the ground) if they fly into a headwind that's stronger than their lowest stall speed. I.e. their ground speed is negative.

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.
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.
An airplane flies at 1000 kmh in still air If it flies into a 100kmh headwind what is it groundspeed?
900 kmp
What is the speed of a Boeing 787 Dreamliner?
The Dreamliner´s groundspeed at cruising altitude is about 480kts. / 550mph. / 890 km/h.
An airplane flies 840 mi in 3 hours with a tail wind The return trip at the same airspeed takes 3.5 hours Find the wind speed and the airspeed?
u said airspeed remains the same, so 840 mi in 3 hrs the groundspeed is 280, for the return trip groundspeed is 240, therfore the wind speed is 40
Does earth's rotation affect an aircraft's flying time?
This is a good question, one that I myself have pondered upon in the past. The spin of the Earth does not only affect solids objects. The atmosphere is also spinning at the same rate as the Earth. From this it follows that when we are flying in an airplane, we are moving forward relative to what's around us: the Earth and its atmosphere. This is the same reason why we're not perpetually flying sideways when attempting to stand still: inertia.
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.
Is aircrafts the plural of aircraft?
The plural of aircraft is aircraft.One aircraft, two aircraft, ten aircraft.
What is an aircraft attitude?
An aircraft attitude is the orientation of an aircraft with respect to the horizon.
Can an aircraft kill a person?
If it is a military aircraft, a light aircraft or a commercial aircraft yes they can kill a person or more.
What is an utility aircraft?
The perfect aircraft to use as a 'Utility Aircraft', would be any type of the Hercules Range of Aircraft.
What is the pluraln of aircraft?
The plural of aircraft is aircraft. Much like how the plural of deer is deer. (Singular: That is such a beautiful aircraft / Plural: Look at all of those aircraft)
