What is a jet stream?

What is a jet stream?

Jet streams are narrow bands of high-speed upper thermal winds at very high altitudes.

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.

If in a go-around, which take-off stages will still apply?

If in a go-around, which take-off stages will still apply?

None. The go around procedure is distinct from the take off procedure. You will still have an acceleration altitude, but you will not have a screen height, V1, Vr, V2, flap retraction altitude, etc.

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.

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 fusible plugs, where are they used, how do they work, why do we have them?

What are fusible plugs, where are they used, how do they work, why do we have them?

Fusible plugs offer protection from tire blowouts caused by thermal expansion that is generated in the tire under extra hard braking conditions.

Do airplanes have an optimum C.G.? If yes, where is it?

Do airplanes have an optimum C.G.? If yes, where is it?

Yes, the closer the C.G. is to the rear limit, the less tail down force is required, which means less drag which results in less fuel burn.

Which way do jet streams travel?

Which way do jet streams travel?

From West to East

East to West (In Africa during the summer)

What do the abbreviations TSRA and MIFG mean?

What do the abbreviations TSRA and MIFG mean?

TSRA: Thunderstorm with rain

  • MIFG: Shallow fog

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.
