Does anyone have any knowledge of the EMI levels which could be
encountered in flight, due to presence of airborne electronic
countermeasures (jammers)?   Current engine FADEC's and aircraft avionics
are Certified to withstand EMI levels of 200 volts/meter.  Is it possible,
assuming normal minimum air traffic control separation distances, that a
commercial aircraft could encounter EMI levels greater than the 200
volts/meter, if some nearby military aircraft (Wild Weasel, EA-6B Prowler,
EF-111, or whatever) happened to light off his jamming equipment, let's
say as part of some exercise??   I'm trying to understand if this could
theoretically be the source of some control system anomalies which don't
seem to have any identifiable cause.
