wrote: Pete, ya did good.... Just a few parenthetical comments to stir the pot... you said the stall warning horn went off 1 second before touch down and the owner said you were slow... When would he recommend that you get the stall warning horn to go off - after touch down? rhetorical question Full stall landings are what you should be doing... With the wheels 6 inches off, the nose should be up and the horn sounding when touchdown occurs... The slower the speed at touchdown the lower the incident of landing accidents...Now, this does not mean you should drag it onto the field with the horn blatting from a quarter mile out and drop it from 6 feet up; but Dennis, you just reminded me of a spot landing contest in which I took part some years ago. One of the planes was a Cherokee 6 and the guy had it loaded. He had three of his buddies in there that must have put it near gross. He dragged it in, chopped the throttle and dumped the flaps. That sucker dropped like some one had pulled the rug out from under it. Man what a sound. It wounded like about half a dozen garbage cans full of beer cans were dropped on the runway. We couldn't find any damage, but I have never seen a plane hit that hard before with out blood being spilled. get the plane established level with the runway and the throttle closed, then keep it off, and keep it off, and keep it off, until the yoke is against your chest and the horn is blatting before the wheels touch... Your tires will thank you, the brake pads will thank you, and your pocketbook will thank you... What the passengers think is not your problem... Actually the Bo likes to do this. If you are't "too high" the horn will sound and then it will just "settle" instead of drop. I've done it from three feet up (I didn't say that) and it was just a "thump", rather than a bang. It's very gentle when the stall breaks if you are in ground effect, unlike what it does on approach stalls when not in ground effect. :-)) With a bit of practice he should be able to land and turn off in roughly 1500 feet without using the brakes. (not on a hot day with high density altitude though). No, this will not result in those perfect greasers that make passengers and many pilots think you are Lindy reincarnated, but perfect greasers are not perfect landings... I can make a perfect greaser at Vso + 30, every time or nearly so... Does that make it a perfect landing? assuming I don't blow a tire, or melt the brakes to avoid going off the end So, what's the rule, Vso + 5, then 5 additional knots for each child, and 10 for the little wifey, and another 5 just to be sure? -and the FBO has to use a cannon to shoot me down before I end up in the next county - The majority want to be able to glide in and that is a good 10 to 15 knots faster than the "desired" speed according to the POH. Let me relate an incident from ~15 years ago, coming in to my home field in my Super Viking.... End of a long day, including bouncing through the thermals for some 600 miles, and I was pooped... Fatigue let me get a bit fast (about 7 or 8 knots) on approach and as I set up the flare and began to wait for the stall horn I went sailing past a pair of the locals waiting to take the runway... I was embarrassed because I knew I was fast long runway, not a problem and I knew they were judging my landing... The following Saturday I am in the pilots lounge and they came in and began to regale everyone with my "perfect greaser"... They were drooling with compliments, "jeez, you went past with the wheels 3" off the ground for half the runway and just greased it on. I shoulda hadda movie camera." They were sincere and they thought it was a compliment... Most of the hangers on in the lounge also were giving me thumbs up, etc... Except for one old A&P from the tail dragger era who simply gave me a long look over his glasses as he took a sip of his coffee... I didn't let on that I was embarrassed about it, though I could feel my ears get a bit red... OK, this has been fun and should bring the experts out of their sandbag bunkers... For getting checked out in your Vee Tailed Doktor Killer, you follow exactly what your instructor wants you to do... Just keep my comments in the back of your head and after it is signed off to you, then do some systematic testing by slowing up by 2 knots each time until you find that speed that is the best compromise in getting the stall horn before touching... All this from a guy who fly's a twin and used to fly a Viking...er ... Super Viking. :-)) Although the Bo will float with excess speed you really have to work at it cuz the durn things slow down so quickly once the gear and full flaps are out. Although the demonstrated cross wind is only 12 knots or so some of them will handle up to a 25 knot cross wind if the pilot is capable. The only thing I'd add, it compare your landing distances to the POH. The Bo is one plane where you should be able to match the POH on landing distance without being an unpteen thousand hour pilot. If the instructor has you using twice as much distance to stop I'd ask him why (politely and maintaining a PC decorum) As Dennis says, Bo pilots as a whole tend to land much faster than necessary. Think of it this way, compare the landing distances for a 172 and then look at the figures for the Bo. I think you'll be surprised. Last summer I had a 172 come in behind me and try to make the first turn off on 06 (terminal building). I easily made the turn off while he went on by in cloud of tire smoke. OK, one more thing... They tend to be a bit unforgiving with full stalls until you get used to them. Then you can put one in a stall and hold it there. Even think about touching an aileron and you definitely will get a chance to practice unusual attitude recovery. snicker. In stalls they are strictly a rudder only airplane.
