EMERGENCY PROCEDURES
generator fails, the battery should not be disconnected during flight.
NOTE: If it is necessary to reduce electrical loads due to an generator mal-
function, switch o electrical components and/or systems that are not essen-
tial for the current flight conditions rather than pulling circuit breakers. Load
shedding in this manner will prevent accidental circuit breaker disconnection
and loss of power to flight-critical systems.
3.11 COMMUNICATION SYSTEM FAILURE
1 Switches, Controls, Volume CHECK
2 Frequency CHANGE
3 Circuit Breakers CHECK
4 Headset CHANGE
5 Transmission ATTEMPT
6 If unsuccessful TRANSPONDER 7600
3.12 PITOT STATIC MALFUNCTION
Static Source Blocked
If erroneous readings of the static source instruments (airspeed, altimeter
and vertical speed) are suspected, the information from the GPS system
should be used for situational awareness. Set cabin air ON.
NOTE: Referring to the GPS for flying, adjust indicated airspeed during climb
or approach. Use +10 KTS on top of standard procedure as guidance and
observe the wind situation.
Pitot Tube Blocked
If only the airspeed indicator is providing erroneous information, and in icing
conditions, the most probable cause is pitot ice. Descend into warmer air. If
an approach must be made with a blocked pitot tube, use known pitch and
power settings and the GPS groundspeed indicator, taking surface winds
into account.
