NG: The subtle scenario is idle descent flameout. The CWS flashes ELEC and the heads go up to the overhead panel. On the upper DU engine gauges you will see 'ENG FAIL'. Depending on windmilling RPM the oil pressure light may stay out. ENG FAIL is the clue, but you need to look for it. It is easy to rush into the first thing you see, i.e. ELEC. Remember the forward instrument panel is not monitored by CWS. That is for MK. 1 eyeball.
