What are the disadvantages of electric aircraft?
Disadvantages of Electric Airplanes Longer charging times: Electric airplanes take longer to charge than traditional powered aircraft take to refuel, which can limit their practicality for commercial use. One leading design for a 30-passenger electric plane is powered by more than 5 tons of onboard lithium-ion batteries, and can only fly 124 miles on one charge.Electric aviation’s biggest hurdle, however, is balancing the energy density of a battery power source. Consider the fact that battery energy is more than 40 times heavier than jet fuel. The battery unit that powered Alice — widely considered the most successful electric plane flight to date — still added 8,000 pounds.
How long can electric planes fly?
The electric airplane range varies greatly by design. A small, two-seat trainer can fly for about an hour. Current battery-electric aircraft achieve approximately 260 km (160 nautical miles), with commercial missions typically limited to under 150 nautical miles due to reserve requirements.

Current battery-electric aircraft achieve approximately 260 km (160 nautical miles), with commercial missions typically limited to under 150 nautical miles due to reserve requirements. Long-haul travel with today’s batteries isn’t possible.A commonly used battery for trainers is a 3S LiPo of 2200 mAh. With this you can usually fly for 8 to 12 minutes. Those who fly quietly and use thermals can extend the flight time to 20 minutes or more.
