Frangible???

Hi!

I've been reading air law all day *yawn* and I am at the section on aerodrome lights and signs. I am bit confused because it is saying that lights and signs should be "frangible".

Why???

Frangible = breakable, so my only logical explanation is that if an aircraft were to crash into one of them, less damage would be done to the aircraft. Am I on the right track or am I being completely stupid?

HI WG

You are right, it's a safety feature.

Yep - I was told (as we were doing some near ground manoeuvres) that the runway lights were frangible and that meant they were 'deformable' in that if we (I) hit one it would break before we did - whether that meant it would bounce back to upright afterwards I don't know and we didin't find out!

Nice word though.
