Pengintai:
As an aside and just for the fun of it I tried to decode your nom de plume. Pengintai is not listed in Charles Huckers “ Dictionary of Official Titles in Imperial China ” , not in any of my English to Chinese dictionaries, not listed in Pinyin and not in my PC translator. Therefore I must assume it is not a real word or a phrase. The secret is yours alone.
However, had you called yourself Ping An then I would have understood. You more than likely know there is nothing, absolutely nothing more important to an aviator than Ping An.
