I asked about what categories do Retro Aircraft fall under? Since they are not listed under the main fleet only the "Modern planes" are.
I also asked if the JS-31 and Dash 7 are available for flight, since both were used in real life with TWE but are not on our fleet page.
1. Retro Division aircraft are available at the trainee rating. So if you search for all the schedules in the "Trans World Retro Division", the flights and aircraft, (707, 727, L1011, DC3, DC4, DC9 etc), are available to trainees.
2. You are correct. The JS-31 and some others are not available in the TWVA Hanger. This is due mostly to finding an acceptable model and livery that we can get rights to either host on the site or provide redirection downloads. You will also find some "holes" in our TWVA flight schedules for certain aircraft for that same reason ... finding data that is accurate and we can reuse.
Lastly, TWVA does allow substitution of aircraft on schedules to allow pilots to fly some of their favorite freeware and payware birds. All we ask is that the aircraft be of comparable range and capacity, and to include a comment in the PIREP about what aircraft was flown. As an example, I enjoy the freeware Thomas Ruth DC-10 and substitute it on some of our L-1011 flights. By the same token, substituting an L-1049 for a L-1011 is not really valid due to range and seating capacities. Check with your Hub Manager if you have a question about something being compatible for substitution.
