What is the washout on a wing?

What is the washout on a wing?

A wing design feature where the angle of incidence of the wing decreases from the root to the tip.

This makes it so that the wing as a tendency to stall at the root first, maintaining aileron control for a longer time and providing a resistence to spinning, facilitating recovery.

What does a bypass ratio of 11:1 mean?

What does a bypass ratio of 11:1 mean?

For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.

Are swept wings effective?

Are swept wings effective?

Swept wings are designed to be the most effective at high speeds. At low speeds, a swept wing produces less lift than its straight counterpart.

At what speed does Mach tuck occur?

At what speed does Mach tuck occur?

Mcrit

What is tire creep, and is it important?

What is tire creep, and is it important?

Tire creep is the tendency of the tire to rotate slowly around the wheel hub as a result of a millisecond landing friction on the tire before wheel spin occurs.

Yes, it is important because if there is too much creep the tire can tear out the inflation valve and cause the tire to burst.

What are the lift qualities of a swept wing?

What are the lift qualities of a swept wing?

Poor, because the sweep-back design has the effect of reducing the lift capabilities of the wing.

Explain what coffin corner is and what happens when reaching the coffin corner?

Explain what coffin corner is and what happens when reaching the coffin corner?

Occurs at absolute ceiling where low speed buffet and high speed (Mach) buffet are coincident.

When reaching the coffin corner, both increasing and decreasing the corner speed will result in a loss of control (either the aircraft stalls, or mach buffeting starts).

What is radiation fog?

What is radiation fog?

Radiation fog forms on cloudless nights with only very light winds and high relative humidity when the cold ground cools the air above it to its dew point causing condensation (fog).

Usually occurs inland in valleys and low lying areas (as these areas tend to have more moisture) and usually occurs in a high pressure system.

What is convergency?

What is convergency?

Meridians converge from their maximum distance apart (at the equator) to the poles where they meet.

Great circles are the shortest distance between two points and convergency represents the change in direction experienced between those points.

Where does a swept wing stall first?

At the tip
