No installation required
The Model 2055 Altitude Alert is a pocket
sized, portable, battery powered device that provides a pilot
with a visual and a voice warning as the aircraft approaches a
pre-selected altitude, or drifts from an assigned altitude. The
unit incorporates a digital LCD display for readout of altitude
and instructions. Simple switch operations allow setting the
current barometric pressure, as well as the assigned altitude
for climb or descent. The unit incorporates a speaker to play the
voice messages. A cable assembly is also included allowing the
voice messages to also play through the pilots headset.
On power up, the LCD reads "BAR-PRES 29.92"
The up and down buttons are used to set the correct barometric
pressure. A simple push of the STEP switch advances the display
to the SET CLIMB mode. The climb altitude is now entered. Once the aircraft has taken off, pushing the
STEP switch starts the CLIMB mode. When the aircraft is about
1000 ft above or below the selected altitude, the display
flashes, and the voice message "APPROACHING ALTITUDE" will be
heard. Once the aircraft is established at an assigned altitude,
a switch push places the unit in the monitor mode. If the
aircraft varies more than 150 feet from the altitude it was at
when the switch was pushed, the voice message "CHECK
ALTITUDE" will be heard.
Pushing the up and down switches together
places the unit in the altitude mode. The unit functions as a
backup altimeter, and displays the aircraft altitude. The unit
will operate about 10 hrs. on a standard 9v battery. A low
battery indicator is included. The unit features an auto shutoff
to prevent dead batteries.
