I have a list of aircraft, I need to be able to recognize by sight (for a competition. I'm in the RAF ATC). Due to the length of the list, I decided to go with an SRS system, commonly used for learning languages.

I know there are a lot of SRS Software platforms that support images, but none that I know of that support a group of images for each card, with the software randomly selecting the image at runtime. The issue is, I need to be able to recognize said aircraft at all angles, and regardless of markings/livery, which means that I need probably on the order of 30-40 images for each one.

Is there any SRS software that has this feature? From what I've read, the one's I've heard of don't. If not, is there any alternative that might work instead? (I'd sooner avoid having to print things out, but will if I have no choice).

Many thanks in advance,
Connor

Shouldn't it be possible to use different cards with the same answer? That way you would have 30-40 cards with different images, but all would have the same answer.

The only caveat that I can think of for that, is that I could very easily have one session, filled with all the same aircraft, and not get anywhere. Granted, viewing the same one two or 3 times a session would be advantageous, however there are limits to how useful this would be, as I view it more and more in one session. I have a list of 276 to learn, after all.
