Probably not.=C2- I may have mentioned that I have an unreliable memory. Due to the nature of LR3 crowbar ov protection, an OV event is followed milliseconds later by a LV event. There would not be any time to sense, display and perceive an OV condition. That behavior I /do/ remember, from years of you repeating it (so that we d ullards might learn it).=C2- And that=99s what spurred my comment =93 the way I understood the OV event in a Z-figure environment, OV would occur and be t erminated before the lamp could heat up; the chances of pilot notice are exc eedingly small.=C2- Other annunciations would be necessary to indicate that an OV event preceded the LV condition.
