It takes a while to get all the systems up and running on the Black Shark because you have to select a lot of buttons in the right order.
To document this as writen descriptions and screenshots would be very labour-intensive and at the same time very boring to read.
Fortunately, Grim Reapers have created a YouTube video for the introduction to the cockpit and the start of all systems, which we have linked below.
Our checklist for starting the aircraft is based on the interactive training. Grim Reapers use different procedure, but maybe it helps you.
So have fun watching and learning!
