Why Airplanes are Usually White in colour?
We all have noticed that most of the planes are white in colour, but why it is so that that none of the planes are colored in red, green or other colors. We all have traveled in planes number of times but none of us found the reason behind this. So if you belong to the same category of only noticing and not finding the answer than my friend you are at the right place as here is the answer for your question.
White is the only color which is the perfect reflector of sunlight. Other colors will convert it into the heat but white has a thermal advantage as it reflects all the wavelength of the sunlight.
Yes painting is very expensive and the cost of painting can run anywhere from $50K to $200K per plane. The 2-3 weeks of time required for such paint jobs will cause loss of revenue for that period. So why to paint.
Coloured planes mean more weight and more weight means more fuel to be used. This will result in heavy operating costs which might lead to huge losses.
# Colored airplanes have lower resale value
Yes it is very much true. Painting an aircraft in a color other than white can negatively affect its resale value as the buyer will have to repaint the plane which will further add more weight to the plane.
# Inspection becomes easy
Airplanes are regularly inspected for cracks, dents, and any other form of surface damage. Nothing works better than white when it comes to spotting a crack on the surface, as the crack is almost always darker than white.
so now you know the answer…………..
