This is probably mainly for Cybermonkey, but do they have some sort of simulation for testing lighting strikes on new planes. I am in debate with my boss and I need to know this/

Its okay to be hit by lightening.
Just knocks a few instruments out.

There is a place in Germany where the can make lightening, was on top gear years ago.

But do they simulate on a new plane before its released?

apparantely the pilots are all made to put a 9 volt on their tongue before the can fly a plane

alan, its a generally tried and tested formula that the electrostatic discharge spikes on the outbaord ailerons are sufficient in the event of a lightning strike. Very rare that you would get any side-effects from it.

So they dont test with new planes then? So when the boeing 767 was released it wouldn't have been tested with a lightning strike simulation?

Yes they do, its called the sparksim2004EGH7ES
ww.google.com will tell you that much

i am not sure, but i highly doubt it. would be a pointless and costly simulation

as you can see in this link, the aluminum aircraft airframe is a very good conductor

none at all, aircraft are hit everyday by lightning. just a bright flash outside is all you would see.
last aircraft to crash from a lightning strike was 40years ago, a 707 got hit and vapours ignited in fuel tank

discharge into the air from the aluminum skin

why did the lightening hit, then go then reappear again when the body flashed?

i think because the lightning passed through the aircraft, but the skin picked up enough charge, and the second flash was the discharge

Pretty sure alot of the flight controls systems have anti-lightening strike circuits built into them, so they can cope with the spikes created. The Aeroplane itself also acts as a Faraday's Cage so does help alot with "rejecting" the energy created by the strike  .

What does it matter, the plane gets hit by lightning the charge normally dispurses straight thru it, the plane has a earth line over it for purposes of keeping the charge outside of the plane, plus the pane is in air, not on the ground, so you cant really be electrocuted, just burnt

They test it with maths and physics. No need to actually test it physically when they can do simulations e.t.c.. on computer.
