1.   Why does Bye Energy believe now is the right time to begin developing an electric airplane?

Alternative energy technology has rapidly advanced and, we believe, is approaching the threshold of viability in aircraft application. In preparation for potential mainstream utility we will examine these technologies and others we have developed on a proof of concept all-electric airplane.

2.   Aren’t batteries too heavy for airplanes?

Batteries used for aircraft need to be as light and energy dense as possible.  Recent battery development has progressed where battery weight and energy density is now approaching sufficient capacity for practical airplane use.

3.   How will electric airplanes be re-charged?

Electric airplanes will be refueled much like plug-in electric automobiles – with a power cord to an electric grid, (ideally, an alternative energy grid).

4.   Aren’t Li-Ion batteries dangerous?

Li-Ion technology has evolved in recent years, and has attained safety levels required for aviation.  For example, a 44 amp-hr Li-Ion battery made by A123 Systems is FAA certified on the Cessna CJ-4 model 525C business jet.

5.   Can the batteries be removed for charging?

The aircraft battery system will be arranged for easy servicing – including charging - if desired.

6.   How many times can a battery be recharged?

Battery life, including the number of full or partial cycles, is rapidly increasing.  Our ideal target system has a multi-year and several thousand cycle life.

7.   Aren’t solar panels heavy?

Solar panels can be made of a variety of different materials.  Some of these material configurations are very light and thin, which is ideal for aerospace applications.

8.   How is solar PV film adhered to the wing?

A special adhesive and surface coating is applied to keep the solar PV attached to the wing surface. The adhesive and coating are designed to withstand fluctuations in temperature, moisture and pressure.

9.   Will the solar PV film increase drag?

The solar PV is actually thinner than a human hair. This keeps aerodynamic drag impact to a minimum.

10.  How long will a flight last?

Our test flights will increase in length from just a few minutes to up to an hour.  In the proof of concept phase we will be evaluating several systems and subsystems, including supplemental energy sources that will impact endurance, perhaps substantially. Stand by for more information as we evaluate these technologies.

11.  What about FAA certification?

FAA certification will be needed for mainstream general aviation fleet applications.  In the proof of concept stage we will work closely with the FAA to determine a checklist of issues to be evaluated in our future FAA (supplemental) power plant certification program.

12.  When will you do the test flight?

Test flights are anticipated in the first quarter of 2011. However, as with any new technology development, many variables may impact schedule.

13.  When will Bye Energy electric airplanes be for sale?

Bye Energy is preparing an electric and electric hybrid propulsion system for application on General Aviation piston-driven airplanes.  We intend to replace the conventional engine with an electric motor and system.  We are not developing a whole new aircraft. We have begun discussions with various customer groups.  The proof of concept evaluations will provide useful data in determining if the program is ready to proceed to accepting customer deposits.

14.  How will the purchase cost compare to a conventionally powered airplane?

Cost specifics are still being evaluated.  The electric motor is much less expensive than a conventional internal combustion engine of equal horsepower.  While batteries are expensive, their price is dropping.  The combined, integrated system, not including thin film PV and other options, will likely be close in cost to the conventional systems they are replacing. 

15.  How much does it cost to fly an electric plane?

At approximately $0.10/kwh, the cost is several multiples less than aviation gasoline.

16.  What are the environmental benefits?

All electric propulsion eliminates combustion pollutants and reduces noise substantially.

17.  What are the safety benefits?

The use of volatile high octane fuel is greatly reduced or eliminated.  Simplicity and robust characteristics are typical of electric motors in contrast to the complexity of internal combustion engines.
