Weather Radar and Lightning?

Negotiating some weather the other day, my colleague was of the firm stance that once we'd decided on a heading to take us on our chosen tactical route, we should turn the weather radar off to prevent it from "attracting lightning" while we were close to the cell.

First time anyone's ever suggested this to me. Is there truth in it?

This bloke has operated all over the world, including lots of ITCZ stuff in Africa for many many decades and was convinced that "1000 volts in the nose attracts lightning like a magnet" and that whenever he's seen any aircraft hit by lightning it's often near the weather radar in the nose.

Aeroplane was B737-800.

Theres no more electrical current in a weather radar than there is any other AC powered system.

The point is to avoid Cbs, not lightning strikes...

Counselling Required.

"Your friend should see a shrink" hopefully immediately after being corrected by Fleet Management or the C P and as soon as possible before they contaminate others thinking on the topic!!!

This one should join the "weather radar deters birds" in the fairy-tales book, once and for all, to be read to toddlers as the sun sets!!!!

I do despair at some of the "wisdom" being aired in these forums, hopefully it is not being taken seriously?

The 'frame is likely charged to tens of thousands of volts already by reason of progress through the air, so switching off the radar is a total dangerous fallacy.

Aircraft inflight static charge is a reality, that's one reason why the helicopter winchman is dragged through the water BEFORE he/she shakes hands with the floating survivor, NOT because the winch operator and the pilot are sadists!!

Hi barnabybleach,

Your friend should definitely see a shrink and buy a pair of these Zaphod Beeblebrox's favorite "Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses": http://www.mostly-harmless.de/joo.html, but keep the weather radar on for the benefit of the other crew member(s).

This wouldn't by any chance be a JetPooh airframe manager?

Thought the Advanced Compass Test would have eliminated this sort of daft thought processes if it is them, not a million miles from the "best kept secret"?!

Like, for example the question discussed in PPRuNe years back asking why do some 737's appear to `crab` slightly when taxiing and viewed from a following aircraft?

Answer was it was due to torque effect caused by rotating anti-collision light. I thought that was a perfectly logical answer.

Coriolis Effect.

Of course the anti-coll light is responsible, that's why they crab the other way in the Southern Hemisphere?

Whoever suggested it was due to the MLG torque links allowing limited castoring should be referred to the same shrink for essential re-programming!
