In time, that will happen with these, too. But the government contracting process for getting those upgrades done is long, slow, and expensive, and I'm happy to have the CRT replacement work when I can get it because it pays well.
But it's interesting to note that digital projectors may not represent a cost savings for a simulator operator. The reason is the cost and frequency of lamp replacement as compared to the cost and frequency of CRT replacement.
For example, the Barco F35 is a modern choice for some simulators. It has two lamps that have a 2000 hour service life and the cost of the replacement lamps is somewhere around 700 dollars each, and the simulator operators are usually restricted by contract to buying authentic parts from an authorizeed Barco parts distributor so they WILL pay that much. Otherwise they void the warranty and they can not afford
to void the warranty on projectors that cost so much.
Over 10,000 hours they'll replace five lamps at a cost of 3500 dollars OR they'll replace 10 lamps at a cost of 7000 dollars, depending
on whether they use dual lamp mode. Sim operators normally do because they don't wan't any down time. Having a projector's only
operating lamp fail during a training session is considered very bad so they run both lamps at once, and change them early during
scheduled downtime rather than wait for lamp failures.
So, at a cost of 3500 to 7000 dollars (roughly) per 10,000 hours, this is in the same range of pricing for CRT replacement at somewhere
between 5000 and 10,000 hours of service on the tubes.
The newest laser source projectors make a much better cost benefit argument in their favor, though. With an expected service life of 40,000
hours on the laser light source, or more, the only thing that can kill their competitiveness would be if the laser source assembly were to cost 30,000 dollars or more. Which it doesn't.
