Long time since I've flown a glider, but I didn't see anything in the last one I flew that would help with an instrument scan, including of course the engine gauges.
Too much adverse yaw to help with basic handling and asymmetric handling practice not much in evidence either.
After Kegworth, it was found that prudent use of the automatics may have reduced the workload sufficiently to enable the crew to run through an effective decision making loop.
