The aircraft I fly, a Fokker 50 twin turbo prop, even has VG's installed inside the inlet duct to the oil cooler which apparently assists in maintaining the flow volume to the cooler by eliminating dead air eddies in the duct which otherwise would have restricted the flow. Great little gadgets ! David. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=290723#290723

    Nick, Once you start looking for them they do seem to be everywhere, they'r e a great aerodynamic fix for local flow problems. Most likely at that location they help keep the airflow attached when the flaps are extended.

    Subject: Flying the Kolb MkIIIC, addendum
    From: Richard Girard <aslsa.rng@gmail.com>
    There was a time I thought the wind only blew north and south here on the Great Plains but no longer. I don't think I've flown more than once or twice all winter when the wind was even close to coming down the runway. It has given me lots of opportunities to test Zulu Delta's ability to slip. One thing I've learned is that no matter the flap position, when you cross the controls her nose comes up sharply. I can almost understand when the wing is clean but you'd think with the strong nose down down moment when the flaps are lowered, it would cancel out, but it doesn't. Doesn't seem to make any difference whether left or right, either. A caution when using full flaps. There appears to be some blanking of the elevator which makes the aircraft more sensitive to local turblulence from buildings and trees while slipping with flaps, but especially so with full flaps. As a result I don't slip her to the deck anymore. Cross controlling to maintain alignment with the runway in minor crosswinds it is less noticeable, but get her all crossed up and hit the torn up air behind a hangar or such and you best be on top of pitch control. There was one approach in particular when I swear that just for a moment it felt like she was going right over on her back. Got my attention PDQ. In conclusion, if you're new to the aircraft, practice slipping at altitude before you need to use it on final 'cause this ain't your daddy's Cessna. Rick Girard

    From: "cristalclear13" <cristalclearwaters@gmail.com>
    I love the longer daylight. Now I have time to go for a quick flight after work on a nice evening, as it was Tuesday. Don't have big mountains or ocean views to fly over, but have a view of the train yard and a forest fire. http://www.youtube.com/watch?v=KdnNCubZA8Y :D -------- Cristal Waters Kolb Mark II Twinstar Rotax 503 DCSI Read this topic online here: http://forums.matronics.com/viewtopic.php?p=290743#290743

    Thanks for the excellent video, Cristal. Until seeing this video it had not register in my brain that your MkII has a duckbillish nose. Looks good and you had a smooth as silk landing. You sure have an abundance of runways there and not much wind to make a difference. Have you ever flown through a forest fire smoke plume? I did it once and it was pretty much what you would expect.
