Subject: | Monowheel, gear warning or just GUMP? |
--> Europa-List message posted by: <rparigor@suffolk.lib.ny.us>
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.

Definitely sounds like it!!! Make sure you check the hardness of the
head
when you remove them and the security of the valve seats,
Are you using the Evans coolant? Or 50% antifreeze mix,

About 2 weeks ago when the OAT was over 100=B0F I had an over temp alarm

the

Subject: | Air Box Falling Off |
--> Europa-List message posted by: JEFF ROBERTS <jeff@rmmm.net>
Hi All,
I am currently adding some strength with 3 layers of bid around the
tubes that the carbs connect to on the air box. They have started to
collapse from the pressure of the clamps. I have had the whole box
come off from the 2 rubber hoses 3 times. Yes I have the brace in the
back going to the motor mount. I even safety wired it to the carbs and
one of the wires eventually broke. It is the standard NACA on the top
of the cowl with the 912-S. Has anyone else experienced this and is
there another way of connecting it to the carbs or reinforcing the
connection to the carbs?
I believe it may be from the pressure of the ram air coming in from the
over size NACA on top. I have all that air going into a plenum thats
mounted to the top of the air box. I was thinking of making the plenum
opening smaller so some of the air just goes into the engine area and
less pressure is placed on the top of the box.
All Ideas are welcome as I am out of them. Thanks in advance for any
help!

Hi Jeff, Bond in some short pieces of aluminum tubing for the clamping area.
It's a combination of pressure (clamps) and heat.

It is important to realise with all stall warning systems whether they
are giving you warnings above a nominated speed or whether they are
giving you a warning that you are approaching a critical AOA.
For example 5kts warning above a critical AOA is better than 15kts
warning above a speed which is the wings level one 'g' stall speed. If
you bank 45deg in level flight the stall speed increases by about 40 per
cent so if your wings level stall speed was 40kts at 45deg bank it
becomes about 56kts. Thus in this case a speed warning of 15kts before
the stall becomes no warning at all whereas a conventional stall warner
or AOA system will still provide the 5kt warning
Nigel Charles
Nigel,
Excellent comments, This is exactly why I produce an AOA system, an AOA is
correct under ALL conditions, it will warn you of the AOA, in our instrument
an audio announcement will advise when about 5% under the minimum approach
speed. Stall warning devices are like closing the door after the cows are out.
To late with to little. An AOA will give proper warning when a trend is
apparent, warning 5 or so below the min approach speed, then the stall warning
5
above the stall. In the US the stall warning certification has one
stipulation ~~ be at least 5 Kts above stall. I've flown some aircraft where
the
stall warning is coming on at 20 above the stall, the owners totally ignore it,
then get into another aircraft and wham~~ enough said.

Hi Jeff
I had the same problem last year. I cut off the collapsed tube from the
airbox and replaced it with some aluminium tube glassed into position. No
further problems in nearly 100 hours and you can do the clamps up as tight
as you like.

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!

Jeff,
Exactly the same kept happening to me. The airbox tubes simply aren't strong
enough, and you can't really tell when they are collapsing.
I have a very simple fix: get a piece of 1 7/8th inch alu tube, cut off two
short pieces and jam them into the inside of the tubes. ACS will sell you
12" for a few dollars.
To ensure that the airbox never comes off, I also jammed a piece of blue
foam between the box and the firewall.
Hope that makes sense.

Subject: | Re: Oshkosh by air - return by Avis |
Richard,
I don't know if my emails get beyond my computer, but here goes:
Ignition could be the problem. It takes higher voltage to arc across
higher pressure fuel mix.
If the ignition coil or distributor cap or rotor or wires have
conductive "dirt" on them, the spark may jump along the short circuit
rather than through the spark plug.
In a borderline situation, a higher throttle setting increases the
combustion pressure enough to force the voltage to a higher level before
arcing, and the higher voltage causes the current to take a short
circuit across the deteriorated surface of the distributor cap, etc.
Reducing the throttle reduces the plug gap voltage required, and the
engine runs normally.
Now why this should occur 1 1/2 hrs into cruise, or at higher altitudes,
I can not guess. Heat distribution?
Your troubleshooting has eliminated the likelyhood of it being a pump or
plug problem.
I have no experience with the Rotax, but in a different engine, I'd
replace the distributor cap and rotor.

I had in mind doing that by means of leaving off the rubber sealing tongue
that contacts the top of the airbox, but in order to use any "surplus" air
for general cooling of the under-cowl/electrics and to allow automatic
venting of trapped hot air after shutdown. The loss in recovered pressure to
the air box is probably negligible as the cowl is already pressurised from
the forward facing nostrils (less what is lost through the exits). No
results yet or confirmation that the flow through the NACA doesn't reverse
at high AoA..

Jeff,
It's a question of temperature and clamp pressure. Note that the tubes are
slightly conic. I found the whole box of pour design. I toke a negative of
it in two halves.
Then I made a new box with a mix of carbon and glass and I insert an
aluminium tube to match the carb intake. Carbon is conductive that is
whatfore I make a layer of glass in contact with the aluminium.
Great pleasure in building,

Jeff,
Exactly the same problem, here. Drove a large socket into the hole to
expand the crushed glass, then added one layer of bid to the outside.
After that cured, I added three layers of bid to the inside. Problem
solved...
Don't close the air duct. You need all the air you can get, to those
carbs...
