7.14.1 L-3 EFIS, L3 ESI-500
The L3 EFIS provides indication of knots indicated airspeed, heading,
roll-pitch-attitude, vertical speed (ft), pressure altitude (ft) or optionally in
meter (m), barometric correction, selected course for display and
slip/skid information.
Basic operation
The MicroSD-card slot must be empty before booting. The ESI-500 does
not have a power ON Switch. The device boots when switching on an
electric power source of the aircraft. After booting splash screen, the
device begins with aligning attitude which may require a couple of
minutes to complete. In that time, the aircraft must not be shaken or
moved. After alignment is complete, the unit is in normal operation mode.
To shut down the ESI-500, all electric power sources of the aircraft must
be
shut down. A warning “Press Menu button for Back-up battery mode”
appears. After 5 min, the device shut down automatically. To speed up
the shut down, press menu button, then select and confirm BATT
shutdown.
Adjust barometric pressure by rotating the knob when the pilot menu is
not active. Millibars (MB) and Hectopascals (HPA) are adjusted in
increments of 1.0 and inches of Mercury (IN) are adjusted of 0.01. Press
the knob to set the standard barometric setting (29.92 In.Hg, 1013 hPa,
1013 mb) when the menu is not active. The barometric display will
indicate “STD“.
