Know you have a problem
before you have a problem!Provides an instantly recognizable voice warning directly in your
headset if low vacuum (or pressure) or low voltage develops.
Includes a red warning light mounted close to
the gyro instruments.
Gyro instruments are essential for instrument flight. Aircraft
vacuum (or pressure) systems that power these instruments have a
high failure rate, and can fail at any time leaving you without the
use of these instruments. Tests have shown that gyro instruments can
start giving false information within less than 1 min. after a
complete vacuum loss. Without the means to instantly recognize this
loss of vacuum a pilot may start to respond to a changing aircraft
attitude that is incorrect without even knowing it. This can lead to
conditions from which recovery is difficult or impossible.
Many
aircraft are equipped with backup vacuum systems, however you must
first know that your instrument power system has failed before any
of these backup systems are engaged. You must "know you have a
problem before you have a problem".
The
P/N 2044 Volt &
Vac Alert consists of a small electronic unit that can be mounted
anywhere in the aircraft. It connects to aircraft voltage,
instrument power (vacuum or pressure), and the aircraft audio
system. A small red light is also mounted on the instrument panel
within the pilots normal gyro scan. Should the gyro power fail, the
pilot will hear the voice message "CHECK GYROS, CHECK GYROS"
directly in his headset. The voice message will sound once, and then
the red warning light will illuminate until the problem is fixed.
The unit can be used in 12v or 24v aircraft with either vacuum or
pressure gyro power systems. It can be installed in pressurized or
un-pressurized aircraft.
The P/N 2044 Volt & Vac Alert is sold as a
complete assembly with everything necessary for the installation
except a 1 amp fuse or circuit breaker.
The system is approved for
installation in most aircraft. Click on
