Quick question with regards to Synthetic Vision Displays, is it possible for these to run off CRT or would the resolution along with display quality be too poor to interpret the visual information and hence why LCD would be much better?
Any points on this matter would be greatly helpful
Notwithstanding the accuracies found in the comments above, the straight answer to your question, “…would it be possible…”, is yes, it is theoretically possible – as long as the system managed to meet the specific requirements that are currently found in the specific requirements for the kind of device on which it would be used. If you read through the requirements for any given level of simulation – depending on what regulatory system from which you plan to seek approval/qualification – you will note that the requirements for the lesser levels of devices are not as stringent and go all the way down, in at least some venues, to the point where visual systems are not required at all; and if used, they must simply not detract from the training being conducted. In fact, there are quite a few CRT-based simulation visual systems currently in use around the world – and, in fact, on the other hand, there are systems in use that very likely wouldn’t stand a chance of pilot acceptance except for the fact that some time ago there wasn’t anything better - and that/those system/s has/have been granted the authorization to remain in use, which is not saying that any such specific system would be found to meet current requirements.
Hope this helps.
