Introduction To Performance; Performance In Icing Conditions - Beechcraft Baron G58 Pilot Operating Handbook

Model G58
Except as noted, all airspeeds quoted in this section are indi-
cated airspeeds (IAS) and assume zero instrument error.

INTRODUCTION TO PERFORMANCE

The graphs and tables in this section present performance
information for flight planning at various parameters of weight,
power, altitude and temperature. Examples have been pre-
sented on all performance graphs.

PERFORMANCE IN ICING CONDITIONS

1. On a clean airplane (no ice build-up) stall speeds are
increased 4 knots in all configurations when surface
deice boots are inflated.
2. Residual ice on the airplane can disrupt the airflow over
lifting surfaces and may cause an increase in the stall
speeds and a change in the amount of warning provided
by the stall warning vane.
3. The wings, stabilizers, and all control surfaces must be
cleared of frost, ice or snow prior to takeoff.
4. Ice accumulations on unprotected surfaces will decrease
climb rates, cruise speeds, and range. Therefore, flight
planning should be accomplished for altitudes where
adequate performance margins exist.
5. Two-engine climb performance at maximum continuous
power will be reduced due to the 130 KIAS minimum
climb speed.
6. The minimum recommended holding speed in icing con-
ditions is 140 KIAS.
