另外維基百科則列了一堆與外交辭令不相關的名詞，比較接近的是ATA模式=非洲旅遊協會模式，大家要認真學習
一般媒體或政府若要表達「先抵達、後公布」這種作法，英文通常不會用 ATA，而會依正式程度與情境使用不同說法。
常見正式表達有：
The visit was announced after arrival.
（該行程是在抵達後才公布。）
The delegation arrived before the visit was publicly disclosed.
（代表團先抵達，之後才對外公開。）
Officials confirmed the trip only after the aircraft had landed.
（官員在飛機降落後才證實此行。）
The trip was kept under wraps until arrival.
（此行程在抵達前都保密。）
※ 媒體常用，但比政府公文稍口語。
The visit was not publicly announced in advance due to security concerns.
（基於安全考量，該訪問未事先公開。）
A low-profile / unannounced visit
（低調／未預先宣布的訪問）
外交與新聞稿裡也常見：
for security reasons
due to operational security
to avoid disruptions
sensitive diplomatic arrangements
例如完整新聞英文：
The minister arrived in Taipei on Tuesday evening. The visit was disclosed only after arrival due to security considerations.
或：
The delegation conducted an unannounced visit, with details released after the officials had safely arrived.
如果你是在寫新聞稿、聲明、國際媒體用語，通常不建議直接寫：
ATA (Arrival Then Announce)
因為英語世界多半看不懂，會以為是臨時自創縮寫。
正式場合會直接描述行為，而不是使用這個縮寫。
