The quest chain is F23->F24->F25. Not F23->F25->F24 as reflected here. (Confirmed through wikiwiki)

The current mistake is going to make people train a Type 21 (Skilled) to Rank 7 or waste one of their existing Rank 7 Type 21 (Skilled) for F24

Recognize the "練度max" as the indicator that of whether you need to use a Rank 7 plane in the quest. (The Japanese description would be useful here to compare since the quest titles are all becoming very similar)
