d. Examples. Paragraph 5-17c gives an example of a call sign. If this was the
call sign of your station, you would identify yourself using prowords and phonetics as
follows: "This is al-fah too dell-tah too ait." If abbreviated call signs were being used,
you would say, "This is dell-tah too ait." Some other examples are given below.

5-20. EVACUATION REQUEST INFORMATION
Before you request an air ambulance to evacuate casualties, you need to obtain
certain information that the air ambulance personnel must have before they begin their
mission. Items "a" through "e" below must be known by air ambulance personnel before
they begin their mission. Items "f" through "i" can be transmitted after the helicopter is
airborne, but should be transmitted with the other information when known. The
information needed for wartime and peacetime evacuation requests is described in the
a. Location of Pickup Site (Line 1). Using a map, determine the grid
coordinates (eight digits) of the site where the helicopter will pick up the casualties.
This information can often be obtained from your unit leader. This information allows
the unit coordinating aeromedical evacuation to plan the helicopter's route so it can pick
up casualties from more than one site if appropriate.
b. Radio Frequency, Call Sign, and Suffix (Line 2). Your radio frequency, call
signal, and suffix can be obtained from your radio operator, from the Signal Operating
Instruction (SOI), or from the Automated Net Control Device (ANCD). This information
is needed so the ambulance personnel can contact you while en route to obtain
additional information (verify pick-up site marking, and so forth).
c. Number of Patients by Precedence (Line 3). Based upon the actual
evaluation of the casualties, determine how many are urgent, how many are urgent
surgical, how many are priority, how many are routine, and how many are convenient.
This information is used by the unit controlling evacuation to prioritize missions when
more than one request is received. Definitions of these categories are given below.
(1) Urgent. Emergency case that should be evacuated as soon as possible
and within a maximum of 2 hours in order to save live, limb, or eyesight.
