1. If the 707 will ever get an update, can there be a model that has two INS units in the Virtual Cockpit vs the Doppler Radar unit and INS?

2. As far as the sounds are concerned, perhaps some more work can go into the environmental sound effects in the cockpit for a more immersive experience.

3. Better exterior lights and customizable cockpit and cabin lighting. (by law the cabin lights should be off under 10,000ft)

4. Improved engine simulation (specifically the startup process)

5. Virtual Flight Engineer to manage the fuel system in a logical and realistic manner.
