What is a example of a push?
A headwind hitting a plane
Does a plane consume more or less fuel with a headwind?
It would consume more fuel - as it would need to expend more energy to fight against the headwind.
Does headwind affect airplane flying times?
yes
How can you have a negative headwind?
In athletics a headwind is expressed in negative terms eg - 5 m/s a wind in your face of 5 metres per second. A tailwind is expressed in positive terms eg + 5 m/s. The positive & negative seem superfluous as a headwind and tailwind are self explanatory
What bird hovers in a headwind?
I think you would mean a kesterel.
What condition reduces the required runway for takeoff?
Increase headwind component.
Why it is difficult to row a boat against the direction of wind?
It is difficult for the same reason it takes more of a physical effort to cycle against a headwind. A headwind is trying to push us backwards, slowing our forward progress. With a tailwind, the wind is helping us to row a boat or cycle faster as it pushes us along from behind. A headwind causes air friction to increase.
Can a passenger plane hover?
Not unless it's in a headwind greater than the plane's stall speed.
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 effect of low level wind shear on aircraft performance?
tailwind which shifts to a headwind causes an initial increase in airspeed.
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.
Can a four engine aeroplane be motionless mid air while all its engines are running?
In general, no. IF an aircraft had a headwind that was faster than the stall speed, it could in theory be motionless in regard to the ground- but the stall speed for most 4 engined aircraft is about 150 knots- that would be a VERY strong headwind. Flying into a hurricane might do it.
