Beechcraft Beech 95 2017 - Cruise Performance Charts

Beech 95 Cruise Performance Chart
Fuel flow values are for two engines. MP means manifold pressure. TAS means true
airspeed, IAS means indicated airspeed.
The following chart was derived from charts in the POH combined with the power computer that comes
with the B-95. The TAS and IAS values were then adjusted downwards based on Selkirk College’s years of
experience operating the airplane. The resulting values are conservative compared to those from the POH
but we feel they are more representative of the actual performance of the airplane.

To use the chart above you must convert your indicated cruising altitude to density
altitude. If your cruise altitude does not appear in the chart interpolate to get the correct
values.
Choose a percent power, for example 70% power. Then in the row corresponding to your
density altitude look up the MP, rpm, TAS, and IAS.
