I had a question. I know common sense would say you need them, but is there anything for Part 91 or 121 that says you must have runway lights to take off? Had a friend that someone reported him for taking off before the tower opened without the runway lights on. He said he turned them on and had to wait close to 15 minutes for his release, and says he honestly can not remember if they had cut off. He is worried now he will get in trouble. There is nothing in the company manual about it either. He said the lights on the plane are so bright, he can not be sure if the runway lights had cut off or not.
