ANDED EMERGENC
Y AND ABNORMAL PROCEDURES
Blocked Pitot or Static Line Suspected
1. Turn Pitot heat ON
2. Open the Alternate Static Source
3. Refer to alternate, airspeed, altitude, and heading sources for primary
flight information
4. Consider exiting IMC
5. Land as soon as practicable
6.1.1. Identifying and Handling Suspected Pitot and/or
Static System Failures
Blocked pitot and/or static system ports will degrade the EFI’s attitude solution.
Therefore, the pilot must be especially vigilant about verifying proper operation of the
pitot and static systems both before and during flight.
It is important to check the pitot tube and static system ports, and to verify pitot heater
performance, as part of a thorough pre-flight inspection, especially when anticipating
flight in low IMC.
On takeoff roll, it is good practice to note and call out “airspeeds alive” when the
airspeed indicators (both primary and backup) begin moving and to compare and
call out readings at a pre-determined airspeed close to, but before rotation speed
(e.g. “60 knots cross check”), consciously noting the performance on each takeoff. If
the airspeed indicators do not come “alive” when they usually do or whenever there is a
significant difference between the primary and backup indicators and sufficient runway
is remaining, aborting the takeoff may be a prudent decision. Follow the Flight Manual
procedures for your aircraft.
