It means that for some reason ram-air is not being allowed into the pitot tube, or the static air system has become clogged in some other way. Most commonly this is caused by forgetting to remove the pitot cover, failing to turn on the pitot heater when necessary, or by a bird or bug strike on the pitot tube. If it can be visually verified that the pitot cover has been removed, the pilot should engage the pitot heat. If there is a backup gauge serviced by a separate system, then that should be used.

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.


Can you change the four forces in flight in any way?

Of course. That's exactly how you steer an airplane. -- Running the engines faster increases the thrust, which increases the airspeed. -- Increasing the airspeed or the angle of attack increases the lift, which makes the plane climb. -- Increasing the drag causes the airspeed to decrease, which causes the lift to decrease. -- Decreasing the airspeed or the angle of attack decreases the lift, which can be used to lose altitude. -- Using control surfaces to increase the lift of one wing while decreasing the lift of the other wing causes the airplane to bank toward the wing with less lift. -- Increasing the angle of attack during a bank causes the plane to be 'lifted' around a turn. -- Extending flaps increases both lift and drag. If thrust is maintained at the same time, the airplane loses airspeed but maintains altitude. Anything you want the airplane to do is accomplished by manipulating the four forces in flight.


What are the effect of changing the angle of projection of the magnitude of range maximum height and time of flight?

Changing the angle of projection affects the magnitude of range, maximum height, and time of flight. A higher angle will decrease the range and increase the maximum height while maintaining the time of flight. A lower angle will increase the range and decrease the maximum height while also maintaining the time of flight.


What describes the difference between the mechanics of airplane flight and rocket flight?

Airplane flight relies on lift generated by the wings due to the airflow over them, while rocket flight operates by expelling propellant out of the rocket engine to create thrust in the opposite direction. Airplanes need to maintain a certain speed to generate lift, while rockets can function in the vacuum of space where there is no air for lift.


2. What are three major factors that can change the velocity and pressure of air flow around a wing and thus increase the amount of lift?

Angle of attack: Increasing the angle of attack of the wing can increase lift by creating more lift-producing airflow over the wing. Airspeed: Higher airspeed results in increased flow velocity over the wing, generating more lift. Aircraft weight: Lighter aircraft require less lift, while heavier aircraft need more lift, influencing the pressure and airflow around the wing.

How do detect a microburst?

Microbursts can be detected using weather radar. A sudden and intense downward air current can cause a radar signature called a radar wind shear pattern. Pilots may also detect a microburst while in flight due to sudden changes in airspeed, altitude, and wind direction.

How high above sea level is an airplane while in flight?

As high as it says on the altimeter. It changes constantly while in flight.


What is the Difference between Give me a man who reads. And Give me w man. Who reads?

The first sentence implies a general request for a man who reads, while the second sentence specifically requests a man who reads. The addition of "a" in the second sentence emphasizes the singularity and specificity of the man being sought.


When car is in park should tachometer read zero?

No, because the tachometer actually reads the rotation of the engine, not of the wheels and therefore reads about 500 RPM while in park.
