So you were hit by lightning... so what
I’ve got a buddy that swears he is a lightning rod. He claims he has been in more planes hit by lightning than any other frequent flyer. He says he can feel the hits in the hair on his arms; he knows the moment they happen.
Well, he does fly a bit more than me, and yes, his arms are extremely hairy, but frankly, I was still a bit skeptical. But then again, maybe I was living through lighting strikes up there in the wild blue yonder as well, and just didn’t have the long arm hairs to prove it.
So I googled it and, sure enough, on www.physlink.com it says “estimates show that each commercial airliner averages one lighting hit per year.” Fortunately “the last
Another related problem with lightning is the effect it can have on computers and flight instruments. Shielding and surge suppressors insure that electrical transients do not threaten the on board avionics and the miles of electrical wiring found in modern air
This makes sense, because
Enter the nvSRAM. On the strike of lightning, the display configurations are automatically backed up in non-volatile. Power stabilizes again, and the non-volatile data is automatically moved back to the SRAM. To the pilot, he may see a flicker as the power surge passes through all his electronics, but his screens and visuals are instantly right back in place.
So next time your pilot’s announcement asks you to buckle up for a bumpy approach, and you see that dark storm cloud looming ahead, just fluff up your arm hairs and smile. Because now you know nvSRAM is up there in the cockpit just waiting to save the displays.
Until next trip, Grant
