I have been creating and running ground courses for pilots and engineers, worldwide, for 18 years.
I currently do this online (Covid style!) for the AW139 helicopter, in two ways:
I can create presentations on any topic, following your company's policies and layout, converted to lively videos, which is ideal for students to watch at their own pace, depending on their operational commitments.
I can also provide specific presentations in real time, using any platform such as Zoom, involving the students in a virtual classroom, and making them feel like they are almost in a real classroom.
You may be interested to see more, here is a short extract from one of my online courses.
But please note, you will see my biggest weakness, my french accent and pronunciation mistakes!
