Final answer:
The statement's truth is contingent on specific aircraft and their electrical systems. Most modern airplanes use multiple generators, whereas a small plane might only require one. Current solar and battery technology is insufficient as a sole power source for aircraft.
Step-by-step explanation:
The statement One generator is insufficient to carry the total aircraft electrical load can be both true and false; it depends on the aircraft's design and electrical system requirements. Modern aircraft typically use multiple generators for redundancy, with each generator capable of handling a portion of the total electrical load. In the event of a generator failure, others can compensate, ensuring continuous supply. On smaller aircraft, however, depending on their electrical system design, one generator might indeed be sufficient for the total electrical load during normal operation.
In the context provided, regarding the impracticality of solar power as a direct energy source for commercial aircraft operation and the reliance on energy storage, it implies that current solar or battery technology does not allow a single power source to effectively manage the total electrical needs of conventional airplanes during flight. While supplemental power or alternative energy sources can be part of an aircraft's power system, they currently cannot fully replace conventional generators or engines.
