What direction do runways face?

They blow away from the poles and curve east to west. Hence, most of the runways are Eastish-Westish (not exactly East-West). Runway directions are largely chosen both for geographic land features of the site of the airport as well as the average local wind directions.

What do the lights on a runway mean?

Runway edge lights are used to outline the edges of runways during periods of darkness or reduced visibility. … The runway edge lights are white. On instrument runways, yellow replaces white on the last 2,000 feet or half the runway length, whichever is less, to form a caution zone for landings.

How long does pilot controlled lighting stay on?

15 minutesThe lights stay on for 15 minutes, plenty of time to land and taxi to the ramp. And if you want more time, repeat the series of button clicks to reset the timer.

The second number differs by 18 or 180 degrees.

Why are runways not flat?

Answer: No, runways are not flat. They are crowned to help drain water off the sides during rain, and often one end of a runway is higher or lower than the other. When preparing takeoff performance calculations, pilots include the slope of the runway.
