Hi everyone.
I think the experienced pilots amongst our community need to stop this
right now and I don=99t class myself in that group. Imagine the
situation, say on take off, your busy in the cockpit to say the least
and you see the engine temp rise into the red,
what do you do, you can=99t shut down, you must expedite a safe
landing asap. If you have time before the engine seizes try to do an
abbreviated circuit and radio your intention with a Pan call and pray
you can get back down in one piece. I am sure other pilots will offer
differing scenarios. The point is if on top of the considerable work
load the pilot has, he now has to somehow manage boiling water and
steam in the cabin, he isn=99t going to do it.
Sorry for being blunt.

What if the overflow bottle was mounted on the cockpit side of the
firewall
where it was visible at all times?

I see what you are say David but in my case it works well, my
Expansion bottle is set high in the centre of the firewall and has a
positive head of pressure back to the filler cap, Twice I have had
small leaks, one from a hose clip before changing to the spring
clamp
type and once from a bottom hose bleed nipple that I had fitted,
Both
times I was aware of the coolant loss long before it became
critical,
I take your point that with a burst hose it probably wouldn't react
quickly enough but thats were my water temperature sender with voice
activated Dynon shouting high temperature in my ears would get my
complete attention,

Ivor, It is not often I disagree with you, but I would guess that
a
leaking or burst hose will let fluid out and air out of/in to the
radiator
system without producing sufficient suction to empty out the overflow
bottle, so that you could boil without your level sensor saying
anything. On
the other hand boiling the coolant is something that is very
noticeable in
air - you get blue fluid all over the screen - experienced when I was
trying
to do a 5 min full power climb to satisfy the LAA with one of my early
model
props.!

I don't quite agree David, if unbeknown to you one of your
hoses/
connections developed a leak when airborne you would be unaware
until
the level dropped below the pressure cap bottle, Once it had done so
it
would effectively stop circulating through the radiator and your
temperature
would start climbing upwards, The sensor is a couple of grams at most
and
IMO would give me a heads up long before it got critical, My expansion
bottle is centre of the firewall as high as possible so cannot be seen
without removing the top cowl, I of course visually check it but on a
long
flight it nice to know that nothing untoward is happening,
For people interested in the sensor I used its a DE4 PPS 10 A01.

Alan, For my money it doesn't really matter what level the
fluid is
in the bottle as long as the level in the header tank is OK,
and I
assume you check that frequently as part of your preparation
for
flight. The bottle is just there to make any fluid pushed out by
thermal
expansion recoverable as I see it. Why add weight and complication?

Hi alan
I drilled into the side of the plastic expansion bottle that
Rotax
supplied, I put her midway so the level would need to drop
to
minimum before the sensor triggered, I will try and turn up
the
type of float sensor I used from my records and let you no,
It's a
simple wiring job once you are through the firewall, Regards

Hello Ivor.
Looks like Lydd is going to become more active know
Manston is
closed.
I would like to fit an indicator the same as you have
done, sounds a
good idea, is there something you can drill and attach to the filler
cap.
Can you give some info on this.
Regards.
Alan

Folks:
I believe the 912 series engines are primarily oil cooled, with some
water and air cooling to help. The engine can be flown at reduced power
for some time after a complete loss of coolant without seizing.
Before I sacrificed myself and my airplane, I'd fly to a safe landing
area to fix the problem.
