CH-750 POWER-OFF FULL-FLAP LANDING TECHNIQUE

I am not feeling comfortable doing power-off full-flap landings in the "Z" Bird. I look forward to hearing from those who have perfected the technique.  Approach speed? Over the numbers? Wind correction? Tips? Please, share your experience!

I use flaps all the time. this is in a 801 . had a 701 and used flaps all the time with it. it slows you down and lowers the nose.you do have to carry the throttle. these planes are dirty, so they will slow down in a hurry with nose up attitude and no power, and the sink rate is quite high so if you are power off with full flaps, you better have the nose pointed down. these things fly well behind the power curve because the wing wont stall, well, it just stays flat and falls out of the sky, i guess you could say its stalled. the 801 is heavier and dont slow down as fast as the 750 would i suppose, so we acually added t the slots on the side of the fuse so we could get the flaps down to 40 deg. well, this lower the nose some more, but created a  a roll to left, not good in windy conditions. we are thinking of adding 3 inches to the chord of just the inoard sections to keep the same speed but lower the nose some more. keep in mind, have a lycoming on front so its kinda hard to see with the nose high. not an issue with the 750 or 701.  also, we landed over a 50 foot tree and came to a complete stop in 750 feet from the tree. you gotta use flaps to get into tight spots. careful in the flare if you wanta keep the gear on it

THERE ARE THREE SECRETS TO MAKING FULL-FLAP DEAD-STICK LANDINGS. Unfortunately nobody seems to know what they are.

for what it's worth . . . if I practice full-flap landings I immediately raise them once on the deck. If I have to go around I give it full throttle, stay low, and gradually raise the flaps.  I've found it has helped to fly with full flaps at 2K AGL to get the "feel" and to see just what to expect.

Michael, good point. I actually had a go around situation last week with full flaps ....throttle to the max and I was hardly climbing in a Puma ultralight Rotax 80hp.. I had to reduce flaps gradually always remaining in the white arc until clear to climb.

Interesting...always learning,,,-:)

In the event that you need to do a go around will the 750 climb with full flaps.  I used to own a J model C150 that had 40 degrees of flaps like alot of the late 60's and earlier models had.  With 40 degrees flaps set the airplane would barely maintain altitude at full throttle in level flight, much less climb.  In the 150 you only set full flaps once the field was made and then you were comitted unless you were landing on a long runway.

Andre - I'm not against full flap landings. I'm against full flap POWER OFF landings. Just clarification. However, you are right, a demo from Roger would help to correct my obvious ignorance of this matter.

Chris, sometimes I'm sarcastic in a humorous (my point-of-view) way, and it occasionally backfires.  Perhaps it did this time. There wasn't a whisper of sarcasim in anything you -- or others -- have shared.  And as far as ability goes the couple of "low-time" sport pilots I've flown with were far more proficient than I am.  Maybe we will be lucky enough to hear a little more on this from Doug Douger, who has more than 300 hours in a demo and could help us clarify technique involved with using flaps in various configurations

On many... many posts we often hear about pilots saying "Oh...don't use the flaps on the 7xx it's too this or too that!!" Everyone seems to want to discourage new pilots to use flaps at all. Why is that??  any technical reason(s)

I whish we could get a Zenith test pilot (maybe Roger) demonstrate via a video the proper and safe usage of the flaps on any of their models. So far I haven't heard any pilot saying good things about the flaps on the 7xx.

they all say..."don't need them at all"... so why have them?  -:) 

Unless none of the Zenith 7xx owners are using their aircraft as a STOL  airplane like they are meant to be.

Any input from anyone really using the full flaps??  Why is it so dangerous??

Peter - I understand; I don't think its cheating (as for as a CFI demands for the maneuver in a BFR are concerned). I do believe the airframe (701/750) has limitations. To land in those "tight spots" shouldn't take a full flap power OFF landing in either plane. I just believe its a dangerous move. I have personally landed my plane on 800 ft. with no flaps. However, it was not fun. I admit I'm NOT by ANY stretch of the imagination someone with your flying experience (I'm a low time pilot). I basing my opinion on my personal experience in my plane and the reaction of that plane when the power is cut. Peter, please forgive me for any misunderstood sarcasm in my post. I was NOT trying to be sarcastic. Fly safe. Chris

CLARIFICATION: Yes, at one time a very, very, very long, long, long time ago I had a bunch of ratings, which made me pretty smart back then . . . but only a smart-ass now. But then I didn't fly at all for nearly 40 years, so at this stage I am back to learning a lot . . . which is the fun part anyway. I do happen to think that you should be able to do most aeronautical stuff in the plane you own & love. No cheating. Isn't anyone out there landing in tight spots on beaches or ranches?
