Question 2:

Ground speed is the aeroplane speed relative to the surface of earth the airspeed with its relative speed is flying the air in
Ground speed and airspeed difference may vary upon the air blowing with the ground speed with airspeed and windspeed
There is difference in the wind and well as ground speed

Question 3:

We cannot use the aircraft engine during the runway because it has higher power
Bigger the size of airplane there is not any wear and tear in it and pilot having any disturbance in landing
It cause debris of the damaged surrounding with the engine failure
Noise pollution caused by the propellers
It can saves the fuel or white petrol

Question 4:

Airplanes can be pushed in the runway by two methods that is taxiing and towing
Taxing is the method by which the aircraft movement is in the yellow line of the aircraft by its own engine power
Speed in this taxiing method is limiter to low speed for accuracy
Towing is the method where the aircraft is moved with the help of a separate vehicle by turning off the aeroplane engines
This method is to reduce the fuel and mostly the noise of landing gear

Question 5:

Take off power is the amount of power where the engine produces limited low power during take off
It is calculated by horsepower in the circuits of aeroplane
Thrust developed in the wings with that of propeller gives the energy to take off the aeroplanes
Tyre design is in which the is designed at high power during landing
Tyres used here are tubeless tyre
Tubeless tyre has high withstanding capacity as of compared to tube tyre
Many heavy parts are manufactured with the aeroplane tyre manufacturing
Rolling resistance is when there is no throttle to the vehicle the energy gas slows down
Energy transferee to the tyre to maintain a consistent speed over any surfaces
This contributes hysteresis loss in associated with rolling tyres
It is very important to maintain the constant tyre pressure of rhe aircraft
This will ensure the safety in addition all the ones are clear
Here the landing gears are disc brakes
Operated to design static all the time they have higher barking time
The efficiency of the brakes are important
