Airlines dim cabin lights for take-off and landing as regularly as they
make safety announcements and checks before take-off and landing.  They
dim the lights in daytime as well as night, so the dimming doesn't seem
to be related to passenger siteseeing considerations.

>From observation, it would appear that the FAA (or A/C manufactures)
require dimming of cabin lights for take-off and landing.  Is cabin
light dimming a requirement?  And if it is, why?
