On an aircraft such as the BE76 Duchess with counter-rotating propellers there is not a critical engine because the yawing and rolling caused from losing either engine is identical.

- Page 11 Fuel The BE76 Duchess uses aviation gasoline, grade 100 (green) or grade 100LL (blue). The fuel system is an “ON-CROSSFEED-OFF” arrangement and controlled by the fuel selectors located on the lower center floor panel.
- Page 12 Certified Flyers II Duchess Multi-Engine Study Guide A min of 9 gal of fuel must be present in each wing tank prior to flight. Total Capacity Total Usable FLIGHT CONTROLS The control surfaces are bearing supported and operated through the conventional cable assembly using push-rods and bell cranks.
- Page 13 (regardless of throttle position). ELECTRICAL SYSTEM Certified Flyers’ BE76 Duchess is equipped with a 12-volt, 35 ampere-hour lead-acid battery installed in a battery box in the aft fuselage compartment. Two 60 ampere, 14-volt, belt-driven alternators provide charging. The output of each alternator is controlled by a separate voltage regulator.
- Page 14 ENVIRONMENTAL The BE76 Duchess is equipped with a 45,000 btu Janitrol gas heater located on the right side in the nose compartment. This provides heated air for cabin warming and windshield defrosting.
- Page 15 Certified Flyers II Duchess Multi-Engine Study Guide The Duchess is equipped with two engine-driven, dry, pressure pumps interconnected to form a single system. If either pump fails, check valves will automatically close and the remaining pump will continue to operate all gyro instruments. A pressure gauge is located on the pilot’s subpanel and a no gyro annunciator light indicates loss of a pressure pump.

- Page 20 Duchess Multi-Engine Study Guide INSTRUMENT APPROACHES The approach speed for the BE76 Duchess is 100 KAIS, this allows for better synchronization with other aircraft in the ATC system. Therefore, speed must be reduced between the DA/MDA before touchdown while “crossing the fence” whether flaps are used or not. Note, with a 100 KIAS approach speed, the BE76 fits into category B approach minimums (91-120 KIAS).
