Air plane - Lights visible -What is the luminuous

04/30/2009 7:25 AM

Hi,

While aeroplane flies, I used to see the light twinkling in the bottom.

How it is vision to human eye? What is the lumninous of light?

I believe that it is supposed to be fly above several hundreds of kilometer from earth.

Could anyone clear my doubt.

Hari

Planes have marker lights. They allow other aviators in other planes to see them and get idea of the direction of travel.

A plane also has head lights.

Planes fly at about 10km not hundreds! So far there is no sustaining air any more.

4 light systems

Marker lights on wingtips and tail in red and green

Strobes on top and bottom - bright white flashes

Livery - sides or outboard on wings in white to illuminate airline company name and tail numbers (only on approach and take off)

Landing - stunningly bright headlights under wings and at nose gear (only on approach and take off)


Don't have the lumens handy, but now you have the names and google can do the rest
