If you're trying to decide on a theory school to study for a Private, Commercial, or ATPL licence for either aeroplanes (airplanes) or helicopters, either before or whilst you're learning to fly, you don't have to travel to an aviation academy, an aviation theory centre, or an aviation school, this is one of the most advanced aircraft theory courses available, and you can do it at your own pace by home study.

Regardless of which aeroplane or helicopter flight school you choose, as you progress through your flight training and gain your Private Pilot Licence (PPL), your Commercial Pilot Licence (CPL), and then your Airline Transport Pilot's Licence (ATPL), you can rest assured that if you use the Online Aviation Theory course (, you will have had the best aviation theory training available, and once you have signed on, you can do as many free online theory tests as you like.

Although the course covers both helicopter flight theory and aeroplane flight theory, the helicopter theory course and the aeroplane theory course are separated, and you will not see statements like 'this is for aeroplanes, and this is for helicopters’.
