The helicopter selection looks very good.
Let’s talk about what tasks can be done with the helicopters. In contrast to airplanes, you can do a lot more with a helicopter than just fly from airport to airport or fly landing challenges. Personally, I think the new flight simulator is really successful, but it has the same problem as its predecessor. For the non-hardcore simmer, it quickly becomes boring without given tasks.
I could imagine a kind of campaign for the planned addon.
As a first example:
For each type of helicopter there is a specific region with coordinated tasks.
For example
R22 / 44 for flight school and training
EC145 for search and rescue flights in alpine terrain
EH101 for offshore tasks
Bell 407 for sightseeing flights and tasks in the city
Bell 412 for transport flights, fighting forest fires
Another campaign example with experience points
You start out with an R22 / 44 and learn how to fly a helicopter. When you have successfully completed this, your pilot career begins. First, you do simple sightseeing flights and passenger flights. You will receive points for every positively completed task. When you have collected enough points, a new helicopter with the appropriate tasks will be unlocked until the largest helicopter is available at the end.
What do you think of the idea with the campaign, top or flop?
