Military Aircraft causing vehicle immobilisers to fail?
Discussion
I was in France this May with my mate riding to Italy on our M/bikes.
We were filling up at a service station on the motorway when a large transport plane (a C130 possibly?) flew over and landed on the other side of the motorway.
Once the plane had passed over, the majority of cars & my mate's bike at the petrol station refused to start.
The lady at the cash desk said that every time a plane landed it caused havoc with peoples cars.
We managed to get matey's bike started after an hour's faffing, but we left a few other stranded motorists waiting for the breakdown truck!!
Would the plane be putting out jamming signals on it's aproach to the airfield, or was it a massive coincidence that all the cars "died" at the same time?

When I was a AAMan it was quite normal to attend BHX to attempt to start modern cars (post early nineties models) that had immobiliser failures and associated flat batteries due to constant "alarm sounding-alarm off-alarm sounding" sessions that only stopped when the battery was flatWe were filling up at a service station on the motorway when a large transport plane (a C130 possibly?) flew over and landed on the other side of the motorway.

Many cases of having to try to overcome immobiliser set cars too!
Not caused especially by Military aircraft but mainly by circuits being zapped by constant high energy airfield emissions. I imagine the Herculeses would use a few high energy radar systems on approach too
(We used to cure many of those "immo" problems by towing them a few hundred yards from the airport buildings)
Key to "go"
Hi Uncle Bob
Brrrmmmm

Transport aircraft and airliners don't tend to use radar as a navigation aid. However, a military Hercules might be fitted with active ECM jammers etc which could cause problems I suppose.
Many years ago I was reading a bike magazine where the journalists recounted an interesting storey. They were speed testing a bike with a hand held radar at Bruntingthorpe when a pair of A10s made a couple of low passes down the runway. The journalists were curious as to how fast the A10s were traveling so tried to get a reading, the hand held radar stopped working with an error code and wouldn't play ball for several minutes despite being turned off/on repeatedly.
I still feel that airfield emmissions are more likly to have caused this
I too doubt if the C130 was emmitting on landing in a peacetime civil airfield scenario
Doesn't even have to be an airfield emissions problem
Next door to Machine Mart in Great Barr, Brummagem there's a Telecoms type building (bristling withh antenna arrays) and I often had to attend immobiliser faults on cars parked nearby
A tow three hundred yards up the A34 to the parking area past the church cured every single one of them, even when the owners had called the manufacturers for help which failed to "help"
Strong signal emissions from a building did cause such symptoms.
Have'nt permitted emissions frequencies been modified and radio frequencies useage changed over the last few years, could this be why?

Unlikely to be emitting in a peacetime scenario, and even then not on finals.ecm is standard procedure for landing

Approach aids.
Vanishingly unlikely, unless this place was using MLS, which is also highly unlikely.ILS installations are far more at risk of having the localiser and glideslope signals being compromised by external factors than they are of affecting any other systems.
More likely a dodgy mobile phone cell station (possibly in the petrol forecourt sign) and a bit of paranoia.
