REFLECTOR: X-wind Landings - Technique Crab vs Slip

[Rene Dugas]

Kevin,

I like to slip down to 500 ft or so if I’m a little fast or high then release the rudder and crab in with a twitch of rudder just before touch down.

It seems stabilized after a few practices.  It sounds like a lot but it’s not.  I land on many 3000 ft runways over trees.  I do not like to be in a slip as I dive for the runway from 50 ft.  I also slip on downwind if I come in fast in a descent to get to gear speed. (XL RG no speed brake)

Your mileage WILL vary.

Thanks John 

Appreciate you sharing your knowledge with us.

Sounds like crabbing is the way for me.

The aircraft can be slipped.  However; I always tell people when they come in for training that it is something that they need to feel comfortable with the aircraft before doing it and the aircraft must have proper control throws.  A slip in this aircraft is like the initial hill on a roller coaster (aircraft has a slight nose down).  Unlike a tractor pull aircraft, you can’t let your speed lower too much because you begin to lose aileron effectiveness.  You need to start the slip with the airspeed indicator pegged on 90kts.  This allows the ailerons to fight the rudders.  However the rudders will win out if you lock-out the controls full.  While the ailerons will be at full deflection, you will have to work the rudder in and out a bit to keep from rolling too far.  Done properly you can lose as much as 2000fpm.  

 

Next time I am up flying I will see if I can have someone video tape what the controls are doing during a slip.

 

Like I said though, you need to be comfortable with the aircraft first before trying to slip it.  Otherwise you will end up trying to land too fast or drifting way off the centerline.  

 

Safe flying,

 

John

I don't think the factory really recommends slipping, but Scott Swing slipped our airplane when he flew it.  I posted the cockpit video here <http://www.velocityxl.com/media.php?do=details&mid=67> .  I may have the same footage from the ground, if I do I'll post it later.
