Hi,

I saw some pictures of aircraft landing on snow covered runways. How they can do that? How is possible to control the plane in such condition? What are the detailed procedures to make this kind of landings?

Thank you in advance for you attention.

I was on the Flt Dk of a A320 on the 23 Dec for a Ldg at Ivalo, Finland.

Autobrake was set at medium, reverse thrust operation was normal and the landing has to be firm to get a grip, no greasers allowed.

Landing on snow itself is not a problem. The rudder is used for steering upon landing so control is no different than landing on a dry runway.

Getting stopped is where it can get alittle tricky. Careful use of reverse thrust and braking along with not making any turnoffs from the runway until sufficiently slowed are the name of the game.

A wise Capt once told me not to make any turns offs from a snowy/slippery runway until your slow enough that you have to actually add power to get off. Wise advice indeed.

>Landing with a B747-200

Landing on wet or contaminated runways requires more
close control over approach speeds.
With a B747 you should accomplish touchdown on the
runway at 1.000 ft from the approach end of the runway. The airplane should be flown firmly onto the
runway at the aiming point. It's very important not to land long! The speedbrakes should be used immediately
after the main gear contacts the runway, because they
destroy lift, increase drag and, most important, increase
main gear loading. It's necessary to use thrust reversers at high power as soon as possible because
they are most effective at high speed.
And the last thing...remember the wise advice  
F.
