the KOEL is found to be inoperative, then
the flight must be canceled and the airplane grounded. For example, a VFR day
flight is planned in a Cessna 172S NAV III
airplane. The strobe light system must be
operational for all four flight conditions
as stated in the KOEL. If the strobe light
system is found to be inoperative during
the preflight inspection, then the airplane
must be grounded. Similarly, if the Garmin
G1000 Cockpit Reference Guide was not
in the airplane and accessible to the pilot,
or the forward or aft avionics cooling
fans were inoperative, then the airplane
must be grounded for all VFR and IFR
day and night sorties. For another example, suppose for the same type airplane an
inoperative landing light was found during
the preflight inspection. A takeoff in VFR
night conditions is planned. Because the
KOEL states a landing light is required for
VFR and IFR night conditions, the airplane
would have to be grounded for the night
flight. The KOEL for this airplane specifies a landing light is not required for VFR
or IFR day conditions.
KOEL AND BACK-UP FLIGHT INSTRUMENTS
Garmin G1000-equipped airplanes usually
incorporate four back-up flight instruments: standby attitude indicator, standby
airspeed indicator, standby altimeter, and
magnetic compass. A frequently asked
question is what back-up flight instruments are required for VFR and IFR day and
night conditions? The KOEL for a Cessna
182T NAV III with the GFC 700 autopilot
addresses this question for each flight condition; a 1 means the instrument or system
is required, and a 0 means it is not required
for airworthiness. For example, the back-up
instruments are required to be operational
for IFR day and night conditions, while the
magnetic compass is required to be operational for all four flight conditions. The
standby attitude indicator, standby airspeed indicator, and standby altimeter are
not required to be operational for VFR day
and night flight.
Concerning the round-dial standby
attitude indicator and the G1000 attitude indicator on the PFD, FAR 91.205
states an attitude indicator is required
for IFR day and night flight; it does not
