I note that my cut-n-paste of these two citations
did not carry the http: links with them. I'm
away from the office but will re-post the
links to these to documents when I get back.
It may well be that there's a bright future for
lithium technology in airplanes. Here's a
supplier of off the shelf devices that has
developed quite a following in the recreational
vehicle and motorcycle markets.

Their batteries are fitted with special
connectors that service a specialized
charger/cell-balancing accessory. While
not 'required' . . . it's very existence
suggests that these batteries are not
drop-in replacements for lead-acid.

But as we all know and personally feel,
the worst thing you can experience in
flight is smoke/fire. Cessna thought they
had cracked that nut. Both Cessna and
the FAA were ready to allow these batteries
aboard John Q Public's airplane.
Obviously, there are some issues yet to be
resolved so that probability for a repeat
incident in flight drops to that magic
one-event-per-billion flight hours that the
FAA is so fond of.
The "oncoming train" remark was inappropriate
. . . energy exploitation has evolved from
basking in the sun to burning wood, burning
pig fat/whale oil and upward to splitting
atoms. Each step offered more concentrated
and energetic releases of heat. Each step
also came with elevated risks.
No doubt risk mitigation for the lithium
technologies will eventually prove adequate.

Hi all,
My dual Nav-Coms do not agree with each other and the GS receiver/idicator is playing
some games :)
Does anyone have a NAV-COM-GS ramp tester that I could borrow/rent for a week to
test the Nav/GS ? Here is a an example of what I need, it does not need to be
exactly the same equipment:

If not too expensive, I might consider buying an used tester, even if itll sit
in the hangar most of the time. AC Spruce has the new product (~$1400), but such
investment does not justify the very limited and infrequent need.
Thanks
Rumen
