Interesting! I've never encountered a 'variance'
with so much perceived significance and
potential risk.
Which airplane?

For what it is worth!
All of United Air Lines' DC-3s had the mixture full forward for idle cut
off, but we also had four C-47s that had been purchased to use as Cargo
Liners and pilot trainers. They had the mixtures set so that full forward w
as
full rich and aft was Idle Cut Off.
We also had some DC-4s in which some fuel tanks were on with the levers
forward while other DC-4s had to have the levers aft for tanks ON.
Many DC-8s had switches on the overhead panel such that ON was forward
while others had the same switches set so that aft was ON.
Makes you learn to pay attention.
Happy Skies,
Old Bob

| Subject: | Engine Fire/Compartment Temperature Alert |
Hey gang,
We'd like a simple way to light up an engine fire/compartment temperature
annunciator on our instrument panel. We will be using a G3X Touch
auxiliary temperature input to measure under-cowling temperatures. But, we
will have a simple on panel annunciator for "Engine Fire" and the G3X
doesn't provide a discrete output for that.
What's the best way to do this? We just need a switch that will close at a
set temperature. We don't know that temperature yet and will use the G3X
measured data to get a normal baseline and set some level above that as a
fire alert. So it would be good if it were a switch that closed at a
temperature and was adjustable? Guessing between 180 - 200 DegF.
Thanks,
Valin

A few years ago, Mark Steitle from Austin texas demonstrated a sensor
and circuit that detected flame, not temperature. It looks for a
specific frequency generated by a flame, You might google flame
detectors to find a similar device

| Subject: | Noisy USB Charger |
I have seven years and 750 mostly trouble free flying hours on my Z 13-8
electrical system. I recently bought a Stratus 2 from Sporty's to give
me inflight weather and TFRs on my iPad. To keep both the Stratus and
the iPad charged on long cross country flights, I installed a cigar
lighter and bought a dual USB charger to go into the cigar lighter
socket.
I bought a dual power (2 USB ports, each 2.1 amps) USB charger from a
nationally known pilot supply company. I tried it with just the Stratus
2 plugged in. After ten minutes, I started getting static on my
communication radio (Garmin SL-30). At first, it was rapidly
intermittent, sounding like some kind of code. After another ten
minutes, it was constant static, sounding like it was breaking squelch.
This happened on more than one communication frequency.
I've never had any radio frequency interference problems before.
Would something like these ferrite toroids help? A friend thought I
should wind both the positive and negative supply wires around separate
toroids.

Beechcraft uses IR sensors in the king airs to detect fire. These should be c
ommercially available.
They are susceptible to false indications when sunlight shines on them direc
tly or indirectly.
