Anyone flying have a monowheel gear warning success story?



I am not yet flying, but from the 20 minute demo flight and what I have

read, you will have a hard time landing a monowheel with flaps up because

you can't see the runway. That is until you slip to landing one day??



What are details of what folk do for a gear warning? 



Opinions if a gear warner is worth the effort, or is GUMP all that is

necessary?



Thx.

Hey Ron!

  I have been flying the mono 5 years now and have not had a single incident 

where

I forgot to put the gear down.  It is the first thing I do on the landing 

checklist and

I check it again on short final.  The retract handle is also the up/down 

indicator.  Also,

the aircraft is very hard to slow down to 65 - 70 mph without dropping the 

flaps and

you would never see the runway to do the approach (unless you were doing 100 

plus!)

I think one would have to get extremely confused to blow it but maybe 

someone could

manage it!  I did have one takeoff where I forgot to retract the flaps/gear 

but I climbed

1000 ft easily before noticing.  I also have no stall warner or stall strips 

although I think the

talking ASI would be nice.

I use 3 microswitches on the main gear lever (one to sense gear up, one

to sense gear down and one to confirm the down lock is engaged). I also

have microswitches on the outriggers to sense when the legs are locked

down. I have 4 warning lights (one red to show gear unlocked, one green

for main gear locked down and a pair of lights to indicate each

outrigger locked down) The lights are mounted in the rear of the gear

lever slot. They are easily seen from the left seat and the recess

ensures that the lights are not affected by strong sunlight.

Yes I know of three wheels up landings, and actually witnessed one. Also got 

close to doing it myself, but fortunately realised the 'picture' was not 

right. If the runway is on an up slope, then the view can look like a normal 

approach attitude with the gear and flaps down. I saw this happen on a grass 

strip. The pilot said everything looked normal on the approach, and didn't 

know anything was wrong until the crunch happened. Also know of two 

incidents where wheels up landings happened after distractions - bulked 

landings, bad weather etc.

I have designed a system using a pressure switch (same as the one used in 

the factory stall Warner) connected to a separate pitot tube. The pressure 

switch operates a buzzer if the air speed falls below 70kts with the gear 

retracted. A micro switch fitted to the landing gear cuts out the buzzer if 

the gear is down. Simple and very effective - almost idiot proof!

Ron,

We now have 130 plus hours with our mono and have never really considered

gear lights, to begin with this was a concern to me as I fly a Piper Arrow

and have lots of horns lights and auto systems to remind me. However, you

would never slow down a mono enough to land without the gear / flaps down,

and to get the gear down you must reduce to low RPM and pitch up - you get

the picture ? to get to anywhere near landing speed (assuming you don't

sideslip for 1000ft) you must have everything hanging out, ofcourse as you

are also decending it makes speed control / reduction even more of a

challenge.



As an aside and purely in my experience and opinion, watch out with adding

all the whistles and bells, the weight of the aircraft will increase

dramatically with little effort. 



Regards



Tony.

Burt Rutan who is a demon when it comes to aircraft weight was once quoted

as saying,  "if you are wondering if to put something on your aircraft or

not, toss it in the air..... if it stays there then its okay to put it on"

Tony

there are a couple of very experienced RAF trained pilots who have 

managed to "wheels up" a mono. I suspect through doing a severe sideslip 

and forgetting what was going on?

You're right thought, the view over the nose at landing speed with flaps 

up should tell anyone something isn't right

Tony,

 I know of five monos that have landed wheel up and two of those pilots had 

over 1000 hours in their Europas when it happened, so I recommend an 

"undercarriage not down" warning for peace of mind if nothing else.

I have Jim Naylor's system of a warning siren at below 70 kts and it works 

very well.  Thank you Jim.  Before that I had micro switches on both under 

carriage and throttle, so that if you closed the throttle when the wheel is 

not down the siren activated, but that can be annoying when you are not 

landing!  However, better than nothing.

Best wishes,

William

Oh yes you can I have seen it done twice and heard of several other

occasions.
