To be clear, once and for all, my concern is with the resolution of the image that the pilot sees. Assuming there aren't more issues hidden in the rest of the system, the big limitation on that image in this discussion (as it stands now) is a 1MP sensor trying to image 90 degrees FOV in a single, fast frame.
Generally agree. Assuming a 1MP sensor, that would seem to be the limiting driver. However, assuming the sensor is upgraded to 4 MP the limiting driver may end up lying elsewhere. We'll have to wait and see what the operators think about the system as it is fielded.
On the other hand with all the F-35 program schedule slippages, a DAS/display upgrade may end up getting completed before the aircraft gets fully operational. As several others pointed out, that sort of tech usually moves very quickly. On the other other hand if the display stuff is tied into the OFP in any way, it will take a long long time to upgrade. My understanding is the F-35 architecture is not very open. If true, then upgrades will be slow in coming. And lucrative for Lockheed.
