FAA Order JO 7110.65W - ATC Procedures, Chapter 10
outlines how ATC should handle procedures for emergency
situations.
しかし、最初のセクションでは、それは言う：
10-1-1(d)
Because of the infinite variety of possible emergency situations,
specific procedures cannot be prescribed. However, when you believe
an emergency exists or is imminent, select and pursue a course of
action which appears to be most appropriate under the circumstances
and which most nearly conforms to the instructions in this
manual.
だから、MaydayとPan-Panについては、10-1-1（a）でこう書いています。
遭難状態に遭遇したパイロットは、「メーデー」との最初の連絡を開始することによって緊急事態を宣言する必要があります
3回繰り返した。緊急状態の場合、「パンパン」という単語も同じ方法で使用する必要があります。
メイデイと汎パンの使用は緊急事態を宣言しますが、緊急事態の性質についてはATCに伝えません。したがって、おそらくコントローラが他のトラフィックをオフロードし、優先処理を行う以外の緊急事態を処理するための特定の方法は、これらの言葉だけではありません。おそらく、あなたの周りの空域の清掃を引き起こします。また、空港や空港の近くにいる場合は、地上を守ります。
Medevacの場合：
2-1-4（b）アウトライン：
Provide priority to civilian air ambulance flights (call sign
“MEDEVAC”). Use of the MEDEVAC call sign indicates that operational
priority is requested. When verbally requested, provide priority to
AIR EVAC, HOSP, and scheduled air carrier/air taxi flights. Assist
the pilots of MEDEVAC, AIR EVAC, and HOSP aircraft to avoid areas
of significant weather and turbulent conditions. When requested by
a pilot, provide notifications to expedite ground handling of
patients, vital organs, or urgently needed medical materials.
NOTE−
It is recognized that heavy traffic flow may affect the
controller’s ability to provide priority handling. However, without
compromising safety, good judgment must be used in each situation
to facilitate the most expeditious movement of a MEDEVAC
aircraft.
最小燃料の場合
2-1-8アウトライン：
If an aircraft declares a state of “minimum fuel,” inform any
facility to whom control jurisdiction is transferred of the minimum
fuel problem and be alert for any occurrence which might delay the
aircraft en route.
NOTE− Use of the term “minimum fuel” indicates recognition by a
pilot that his/her fuel supply has reached a state where, upon
reaching destination, he/she cannot accept any undue delay.
This is not an emergency situation but merely an advisory
that indicates an emergency situation is possible should
any undue delay occur. A minimum fuel advisory does not
imply a need for traffic priority. Common sense and good
judgment will determine the extent of assistance to be given in
minimum fuel situations. If, at any time, the remaining usable fuel
supply suggests the need for traffic priority to ensure a safe
landing, the pilot should declare an emergency and report fuel
remaining in minutes.

ATCが特定の状況でどのように動作するのかを知るには、本当に（長い）文書全体を読むべきです。第2章第1節には緊急事態が数多くありますが、そのほとんどはパイロットが求めている優先事項と援助を提供するものです。
