3.12 PITOT STATIC SYSTEM 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.
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 ground speed indicator, taking surface winds
into account.
