CrossWord Aviation Puzzle

航空填字游戏，包含有关航空世界的问题。

A crossword is a word puzzle and word search game that usually takes the form of a square or a rectangular grid of white- and black-shaded squares.

The goal of solving the puzzle is to write different words, letter-by-letter, in the white squares. Next to the grid is a list of clues. The answer to each clue is a word or sometimes a phrase. The place in the grid where the answer to each clue should go is shown by a number and the direction in which the answer appears.

Gameplay features :

- Fill in the crossword puzzles horizontally and downward

- There are hints that can unlock hidden letters, but this will reduce the challenge of playing
