For when a character who's perfectly capable of flying is faced with a problem or doing something unnecessary, conveniently forgetting their powers.

This shouldn't include simply running (could conserve magic), riding vehicles (could be faster or less effort), or events with short reaction times such as tripping while walking. This is meant more for things where they have no real excuse for not thinking of it, like being unable to reach something or falling off a building.

Often seen in Touhou fanworks, since nearly every character is seen to fly under their own power in the games. A few are up to interpretation: Kirisame Marisa might require her broom to fly, Wakasagihime may have only been swimming, and most characters not appearing in the games have never been seen to fly.

AU settings for any work should not be included unless it is confirmed that the character(s) can still fly.
