Trimmed the plane and used my normal landing procedurs except hoding the gear up until the landing was assured. It was a non event except as John mentioned above it became a ground steering problem once I slowed to a taxi. -------- Milt N395V F1 Rocket Read this topic online here: http://forums.matronics.com/viewtopic.php?p=6713#6713 ________________________________ Message 3 _____________________________________ Time: 06:39:02 AM PST US From: cloudcraft@aol.com Subject: Re: Commander-List: flaps and flexibility --> Commander-List message posted by: cloudcraft@aol.com Outstanding advice from Bill Leff. Since Mr. Leff brought up the icy runway idea ... the ONLY time I'd use less than full flaps when landing a Twin Commander was if I was carrying airframe ice on the approach. Full flaps could aggravate a tail plane stall. I wonder if anyone else caught the very sublte but very important hint: Bill Leff is offering Commander Training. If I was looking for Commander training, I'd go to him (and I used to make my living doing Commander training!). I've landed in snarling, ripping, Santa Anas tumbleweed blowing, sand-blasting, 90 degree cross winds in a Commander. Full flaps. Differential power does the trick, coupled with that nice high wing that allows all the side slip bank angle you could ever want. Wing Commander Gordon Imperial Meat Pie?

Use differential power when exceeding more than 1/2 rudder travel. When on the ground the aircraft has a negative angle of attack and sticks quite well. Raising the flaps after touchdown helps some but they retract so slow you will be stopped before they are completely up.

It was Keiths intimate knowledge of the 685 that enabled me to finally become a competent pilot and a complement from Keith is indeed high praise. -------- Milt N395V F1 Rocket Read this topic online here: http://forums.matronics.com/viewtopic.php?p=6728#6728 ________________________________ Message 5 _____________________________________ Time: 11:43:54 AM PST US From: "Robert Steele" Subject: RE: Commander-List: flaps and flexibility --> Commander-List message posted by: "Robert Steele" I will second WCG's suggestion on Bill. And I speak from experience. I bought my Commander without having my ME rating. Dick Wartinger did the pre-buy for me and then hooked me up with Bill. At the time Bill was an MD-80 instructor at TWA (now American). Due to insurance requirements I had to spend 25 hours with him and I can tell you he did everything in the world to me - including pulling engines on take off roll - before and just after take off (and on hot days). Bill is definitely old school as well as new school. I think I was his first piston student in 20 years - so he insisted on the best of the good-old-days as well as the new stuff of today. One of the best things he had me do was may make an actual single engine landing - not simulated - but feathered left engine out - and because of his training it was a snap - and it was as if he had ESP. To make a long story short - on my ME check ride (with a for-real FAA employee as the examiner) I actually had to make a single engine landing. It was a very hot summer day in August and we were 10 miles from the airport with the right engine out (long story there). Due to Bill's training I was not a bit nervous and the landing at Lunken was a breeze - even taxied all the way back to the FBO and parked her in an out of the way spot! (I got a discontinuance because the FAA man wanted two to see two more take offs and landings - which he got out of me two weeks later.) Thanks to Dick Wartinger I now a have a great instructor and a friend.
