Can we file alternate all the time even if the weather is good? If I understood right 91.169(c) says we cant.

    There is nothing in 91.169 that prohibits you from filing an alternate any time you wish, good weather or bad. What are you reading that makes you think you can’t file an alternate in good weather?

    It’s actually a good and reasonable practice to do so.

    91.269 says you must file an alternate unless certain conditions apply. Like Russ, I wonder what you are reading into what it says.

    Ah… I think I understand your confusion.

    61.169(c) does not deal with =when= to file an alternate. It tells us what the minimum forecast weather conditions must be =at the alternate= in order to use it as an alternate.

    IOW, we cannot use an airport as as alternate unless our weather sources “indicate that, at the estimated time of arrival at the alternate airport, the ceiling and visibility at that [the alternate] airport will be at or above” certain minimums.
