What is lift?
What is lift?
Lift is the component of the total aerodynamic force perpendicular to the relative airflow.
Lift is generated when a streamlined body, such as an aerofoil, is placed in a flow of air.
How can you calculate Vref?
How can you calculate Vref?
Vref = 1.3 x Vs0 (stall speed in the landing configuration).
While climbing with a SEP, in what temperature range can carb icing occur?
While climbing with a SEP, in what temperature range can carb icing occur?
Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.
What are wing tip vortices?
What are wing tip vortices?
Wingtip vortices are tubes of circulating air that are left behind a wing as it generates lift.
They are caused by the difference in pressure above and below the wing causing the air to 'escape' from the high pressure area below the wing to the low pressure area above the wing, by rolling around the tip of the wing. This creates a vortex that trails behind the wing.
Why don’t you want to fly your Seneca into a thunderstorm?
Why don’t you want to fly your Seneca into a thunderstorm?
Due to the structural damage that may occur in thunderstorms, due to hail, severe turbulence and severe windshear.
Besides that, lightning strikes may cause damage to electrical systems and severe icing may occur.
Can VMCG be lower than V1? Explain.
Can VMCG be lower than V1? Explain.
Yes, VMCG has to be equal to or less than V1 to ensure the aircraft could maintain runway heading having suffered an engine failure at or above V1 when the aircraft is committed to takeoff.
Can you explain what a coastal breeze is?
Can you explain what a coastal breeze is?
A coastal breeze is a wind from the sea that develops over land near coasts.
It is formed by increasing temperature differences between the land and water; these create a pressure minimum over the land due to its relative warmth, and forces higher pressure, cooler air from the sea to move inland.
Generally, air temperature gets cooler relative to nearby locations as one moves closer to a large body of water.
Why is anhedral used instead on some aircraft?
Why is anhedral used instead on some aircraft?
Anhedral:
compensates for the wing sweep improves roll maneuverability
What is the typical range of an NDB?
What is the typical range of an NDB?
Average range over land 20 - 25 miles.
Range for an NDB can be calculated with:
2√power output in Watts = Range (Land) 3√ power output in Watts = Range (Water)
How does an aerofoil work?
How does an aerofoil work?
An aerofoil is a body shaped to produce an aerodynamic reaction (lift) perpendicular to its direction of motion, for a small resistance (drag) force in that plane. It achieves this by accelerating the flow passing over it, and decelerating the flow passing under it. This change in velocity causes a change in pressure, which in turn generates lift.
