Hello all,
Sorry for my later reply. Busy these days.
Thank you all for your information, tips and ideas. Very helpful.
For slasher: during my research, I also found information about that kind of flaps. But since I thought to post my question on a 'Professional Pilots Rumour Network' forum, I thought I would not get any reply with information about that .....
Again, thank you all, and I will maybe later post some questions, where we possible can't find an answer for.
Thanks,
Quinten
