PILOT’S GUIDE

What’s UP With
Backup Instruments?

hey sit there quietly in the panel, hour after hour,
year after year. Few pilots hardly take any notice
of them. Like health insurance, they’re looked
upon as something you must have, but hope you never
use. Then, one day, when you’re in the soup and your
electrical system goes dark, these tiny dials become your
best friends.
I am, of course, referring to backup instruments. Long
thought of as the proverbial “redheaded stepchild” of

the panel, backup instruments are becoming the center of attention of many new-generation glass panel
upgrades.
“Pilots look at their analog backup instruments and
start to say, ‘well, that seems to be the weak link in
the panel now,’” explained Bob Jacobson, owner of
Custom Avionics. “If we replace those legacy mechanical backup instruments with electronic instruments that
provide the same information and capability available
from the primaries and do it with more robust and
reliable technology, then pilots will have substantially
greater confidence in the system as a whole.”
Too true. Owner/pilots have continued to upgrade
from analog instruments to glass for their primary instruments, and today, there’s no reason to stop there.
“There’s certainly been a lot more interest and
demand since people started upgrading to glass panels,” Jacobson said. “The various STCs require you
to have the backup instruments as separate systems
from the primaries. So, if you have all glass, then you
can have vacuum gauges as a backup.
“Of course, many pilots want to get rid of the ongoing maintenance required by a standard vacuum system. They (vacuum pumps) are usually good for about
500 hours but are supposed to be changed every 400
hours. If you want to get rid of the vacuum system and
use another electric unit as the backup, then you need
to have a separate power source installed.”
The secondary electrical source can be in the form
of a separate battery, or just install a new-generation
instrument like a Mid-Continent LifeSaver, which has
its own built-in battery.
