Section 921
Lycoming AEIO-580-B1A Engine
921.5 PERFORMANCE
Due to the slightly increased power as well as the similar brake specific fuel consumption of the
AEIO-580-B1A engine compared to the AEIO-540-L1B5 engine, the performance data given in
Section 5 of this handbook are considered to be conservative thus can be applied in general.
Even at 2600RPM the climb performance is slightly better than that of the aircraft equipped with
the AEIO-540-L1B5 engine. The actual value of the climb rate at MTOW 950kg (2095lbs), SL, ISA
and T/O power with 2600RPM is established as 2163ft/min.
However, the Cruise Performance Charts and related Drawings have been adapted with regard to
the power settings. The power settings are adjusted to match the absolute power values in the HP
column of the Cruise Performance Chart presented in Section 5 of this handbook. For this reason
the %-values of the power setting column deviate from the common values (75%, 65% etc.).
In the Cruise Performance Chart for configuration 2 the increased fuel capacity of the center tank
has been considered.
921.5.1 Cruise Performance Chart Configuration 1
Configuration:
T/O Weight 950 kg (2095 lb)
Center Tank Fuel Capacity 51 L (13.4 US gal)
Total Fuel Capacity 171 L (45.2 US gal)
Range and Endurance values include fuel for warm-up and Take-Off from SL, max. cont. Power
climb to cruising altitude, and a reserve of 21 L (5.55 US gal) for 45 minutes with 45% Power. 5.5 L
(1.45 US gal) unusable fuel is taken into account. (At ISA-Conditions.)
