Using flaps during landing

[mikeglaz]

I'm practicing landing in the LaGG-3.  What should I be doing with my flaps during a landing approach?  Actually, what is the purpose of flaps?

You should extend them fully. They slow the aircraft down and provide extra lift. This means you can land at a lower speed, and you can drop the nose for a better view at the runway during approach. The lower speed and the added drag also mean that you can stop within a shorter distance after touchdown.

Primary purpose of flaps is to shorten your takeoff and landing distance by allowing you to go at lower airspeed than in clean configuration (flaps retracted). In the Bf-109 for example landing speed without flaps is about 160km/h whereas with full flaps it's 130km/h.

 

Usually you need to set your flaps once arriving on the leg before the final approach. It's better not to extent flaps fully before having turned in for final as you're running high chance to overpull and stall the aircraft. Once on final you can drop them step by step until they're fully deployed.

 

As for the Lagg-3 flaps are very important on landing due to the heavy airframe and tricky handling making high speed landings difficult. In some cases however you're better leaving them retracted, for example if one flap has been shot off or your wings are badly damaged.

Ignore the speeds from diagram (not for Lagg)

 

Set trim for 'hands off' final approach

 

Use throttle to adjust rate of descent 

 

Use stick/control column to adjust speed

 

practice a lot 

 

maintain circuit altitude + - 50ft

 

maintain circuit pattern headings + - 5 degrees

 Even the girls use them
