Graham, Brian:
Good points about the accuracy vs fuel density - i hadn't thought of that though
i'm not sure what the worst case error could actually be. I omitted to say
that i also had a FF meter and whilst that is more accurate, it is only so if
one remembers to dial in the amount of fuel added to the tank each time - since
it only subtracts from its 'total' qty based upon the flow rate. For this reason,
i think any 'manual' gauge is a very useful cross-check. I found the lumpy
change in level with the magnet and pole type level sensor to be rather confusing
occasionally. Incidentally, I recently bought kit 121 that Gerry Cole
started back in 1994 - he has fashioned (approved by Jon Tempest) a separate
manometer style tube into which the float type sensor screws - enabling a manual
check of fuel level - image below i hope. Clive

How I wish I=92d been aware that this was possible when I installed
mine=85at the time, as I recall, there was a builder who claimed to have
succeeded in following the directions for a retrofit within the head
rest, but for the life of me I could never imagine how that was possible
nor can I imagine how any maintenance can be performed through the
inboard access hole if the gauge is located per build manual.
I am satisfied however that if necessary, using my trusty razor saw, I
will be able to remove, add flanges, and replace a portion of the head
rest sufficient to provide access without compromising the structural
integrity of the plate for the shoulder straps and the potential
compression loads in the event of a hard landing.

| Subject: | re: ground/earth |
I obviously opened a can of worms with this topic. My only intent was to
draw attention to strict instructions when installing radio equipment - not
just VHF transceivers but any device sensitive to small signals.
I have no quarrel with fellow builders but the last correspondent mentioned
"noisy grounds" and "quiet grounds". The 'forest of tabs' I found to be an
excellent organiser of various aircraft ground return paths - and have used
it since the day I saw it. This can be a 'noisy' ground because it is
subject to all the noise (strobes, large on/off selections and even received
radio signals) - that's because they are meant to be DC sources.
Ah, but the 'quiet' ground probably sits somewhere on the radio set. It is
designed to absorb the noise created and then subject it to circuitry before
unleashing it on the aircraft ground. If the coax is to be grounded ( and
thus be free of interference) it goes to the quiet ground first.
All I wanted to say was - be sure to follow the radio installation
instructions to the letter. The fault lies with the use of "ground or earth"
for both points. We need another term for radio ground - maybe "quiet"
works?
Cheers, Ferg
P.S: I heartily endorse Bob Nuckolls' (AeroElectric) advice - I invited him
to conduct a well-attended lecture at our hangar

Hi Rod.
I take it you mean the port side pilots headrest locker, and just outside of it
so you can cut the hole much more easily .
So the hole is not actually in the locker but on the outside.

| Subject: | Re: 57 minuts on 13 ltrs on a 914 |
Hi All.
Did another check today, Air bourn times, 1.04 min and 1.32 min
total 2.36 mins or 2.6 hrs, took 38 litres to top up, so 14.6 average ltr/hr this
dose not include the 30 min taxing around on the ground and doing the power
checks.
Still can,t get the flow meter correct, it asked for 46 litres but I could only
get 38 in the tank. So over reading by 8 litres on this occasion.
Alan
