Weather data collected near the Earth’s surface
What are surface observations?
Air moves from high pressure to this.
What is low pressure?
The horizontal distance of how far you can see.
What is visibility?
Under this, pilots fly by looking outside.
What is VFR?
Irregular up and down air movement?
What is turbulence?
These observe weather from space
What are satellites?
Wind direction is measured in this unit.
What are degrees?
Visibility is measured in this unit.
What are kilometers?
Under this, pilots can fly inside clouds.
What is IFR?
When ice forms on aircraft surfaces during flight.
What is ice accretion or icing?
These factors are included in aviation weather forecasts.
What are visibility, wind, clouds, pressure, temperature
Wind speed in aviation is measure in this unit.
What are knots?
This is the height from the ground to the lowest significant cloud.
What is a cloud ceiling?
Under VFR, pilots must avoid these.
What are clouds?
Wind flows around this, resulting in wind shear.
What is an obstruction?
Weather forecasts concern all the conditions that affect aircrafts during these three phases.
What are takeoff, approach, and landing phase?
These are the three factors that cause wind.
What are pressure, Earth's rotation, and topography?
These clouds are tall, puffy, and can cause storms.
What are cumuliform clouds?
Under IFR, pilots receive guidance from these people.
What are air traffic controllers?
This is where ice accretion primarily occurs on the aircraft.
What are leading edges?
Data collected from temperature, pressure, humidity, wind, and precipitation near the Earth’s surface are used to make these models to predict future weather.
What are Numerical Weather Prediction Models?
What is wind shear?
This is the maximum height of cloud ceiling for a cloud to be considered significant.
What is 6000 meters?
Flying inside clouds is allowed under this.
What is IFR?
These characteristics of an aircraft change when ice accretion occurs.
What are aerodynamical characteristics?
