FAA Approved Airplane Flight Manual Supplement

Hawker Beechcraft B300 and B300C King Air 190-00716-03 Rev. 3
Page 50 of 139 FAA APPROVED
If Copilot and Standby Altimeter Agree (Pilot Altimeter Differs):
NOTE
The standby altimeter must be corrected for position error using the Altimeter Correction –
Standby System chart in the Performance section of this supplement.
3. Autopilot ALT Mode .................................................................................................... DISENGAGED
4. Pilot’s Static Air Source .................................................................................. SELECT ALTERNATE
A sudden sustained change in rate-of-climb indication accompanied by abnormal indicated
airspeed and altitude changes beyond normal calibrated differences observed on the Pilot’s
PFD would indicate a blockage of the pilot’s static system.
• If Pilot’s and Copilot’s altimeters agree within normal calibrated differences with Pilot’s Alternate
Static Air Source in the ALTERNATE position:
Refer to Section 5, PERFORMANCE in the aircraft AFM for Airspeed Calibration-Alternate
System and Altimeter Correction–Alternate System for the Pilot’s Altimeter.
• In RVSM Airspace:
5. Altitude ............................................................... CROSS-CHECK USING STANDBY ALTIMETER
Record each altimeter reading for contingency procedure use
6. Advise ATC of loss of redundancy of primary altimetry systems. Perform appropriate RVSM
contingency procedures outlined in the operator’s RVSM manual for the loss of redundancy of
primary altimetry systems.
If no change in rate-of-climb, airspeed, or altitude is observed:
7. Pilot’s Static Air Source ........................................................................................ SELECT NORMAL
8. Compare indicated altitude to GPS altitude on MFD AUX-GPS STATUS page to aid in
determining which primary system is most accurate.
NOTE
When comparing indicated altitude to GPS altitude, deviations from standard temperature or
pressure can cause indicated altitude to deviate from GPS altitude. Those errors are largest at high
altitude. Below 10,000 feet with the correct local altimeter setting set, GPS altitude will usually be
within 600 feet or better of the correct indicated altitude. Use the following guidelines to help
estimate correct altitude from non-standard conditions:
• Temperatures WARMER than standard can cause GPS altitude to read HIGHER than indicated
altitude.
• Pressures LOWER than standard can cause GPS altitude to read HIGHER than indicated
altitude.
