DEScR/OPERATION
Standby Instrument (continued):
The Aspen Evolution EFD1000 is a fully digital, independent flight instrument
display which provides attitude, barometric altitude, airspeed, heading, vertical
speed, slip/skid and turn rate indications. The purpose of this flight instrument
is to provide a reference to crosscheck the G1000 system information for
system reliability and to display basic flight information during a G1000 system
failure.
The EFD1000 is located to the left of the PFD in direct view of the pilot. During
normal operation, power is provided by the essential bus. If both alternators are
inoperative, the EFD1000 will continue to operate on the essential bus until the
primary battery is depleted. The EFD1000 will then operate on the emergency
battery/bus for 30 minutes, permitting the pilot to find a suitable landing
location.
In the event of a complete electrical failure (loss of both alternators, and both
the primary and emergency batteries) the EFD1000 will revert to its internal
battery allowing approximately 30 additional minutes of operation. If this
occurs the EFD1000 will illuminate an "ON BAT" annunciation and display an
estimated battery charge state.
The EFD1000 and emergency bus must be checked for proper operation prior
to flight. Verification is accomplished in the BEFORE STARTING ENGINE
checklist, and again if necessary, in the GROUND CHECK checklist. IFR flight
is prohibited when any component of the emergency or standby systems are
inoperative.

7.11 LANDING GEAR

The Seminole is equipped with hydraulically operated, fully retractable,
tricycle landing gear. On takeoff, the gear should be retracted before an airspeed
of 109 KIAS is exceeded. The landing gear may be lowered at any speed up to
140 KIAS.
