significantly in air ambulance operations, in which
the aircraft is fine but the occupant(s) may be
endangered.
“Order 7110.65 requires the controller to “…give
first priority to separating aircraft and issuing
safety alerts as required in this order. Good judgment
shall be used in prioritizing all other provision
of this order…In conjunction with paragraph
2-4, therefore, any aircraft that identifies itself as
a ‘Lifeguard’ flight…will and in fact, does, receive
a very high priority in the air traffic system.”
“Lifeguard” can be confused with another commonly
used aviation term, “Priority Handling,” which is further
explained by FAA Air Traffic Procedures Division:
“The term and usage of ‘Lifeguard’ must be contrasted
sharply with the term and usage of ‘Priority
Handling.’ ‘Priority Handling’ means that the pilot
requests priority handling, and has no other connotation.
Unless the pilot further specifies or clarifies
that request, it means nothing more than any other
request…Given the ambiguity inherent in the term
‘priority handling’ and with no other indication or
rationale for the request, it is unlikely that the
controller would provide service reserved for air
ambulance flights.
“Good communications between pilot and controller
provides a safer and more efficient operation for all
concerned. Awareness of an emergency or nearemergency
situation provides the latitude for both
the pilot and controller to effectively perform the
task at hand…Controllers share with emergency
medical personnel a high degree of awareness of the
value of human life: it is a natural alliance.”
The following table summarizes the information provided
concerning the terms “Lifeguard” and “Priority
Handling”:

The key to any good relationship, whether in marriage,
at the office, or between pilot and controller is communication.
Pilots and air traffic controllers know that the safe and
efficient movement of air traffic requires good voice communication
between air traffic control facilities and aircraft, yet most pilots
and controllers have experienced a loss of communication at least one
time or another, for a variety of reasons.
A Near Thing
The following event, reported to ASRS by several participants,
illustrates the problems that can arise when
communication is not possible. A Center facility had
jurisdiction over two air carrier aircraft, both at flight
level 350 and on a nearly head-on converging course.
The Captain of air carrier X writes:
✍ “…We were given a routine radio frequency
change…We tried to check-in on the new frequency
several times, but were blocked by other transmissions.
The Controller on this frequency was extremely
busy…While waiting for a break to check-in,
my First Officer called out traffic to me at the 2
o’clock position. The traffic, a wide body [jet], was in
my blind spot (behind a windscreen post). When I
saw the aircraft I watched for approximately 10
seconds and determined we were on a collision course.
I initiated an immediate descent out of 35,000 feet.”
(ACN 187551)
The First Officer of air carrier X adds:
✍ “…I figure we missed by 800 feet vertical separation.
He went directly over us. I’m sure we would have
collided had I not seen this aircraft.” (ACN 187556)
And a Controller provides the conclusion:
✍ “This near-miss occurred because air carrier Y
didn’t maintain a radio watch over the whole northern
hemisphere while on a…[trans-Atlantic] flight,
and another aircraft was not retrieved from a wrong
frequency by a supervisor working radar— because
of human error…Air carrier Y never saw air carrier X.”
(ACN 189213)
Several communications-related problems occurred
here, including the flight crew of air carrier Y not
maintaining a listening watch on frequency, and aircraft
X being sent to the wrong frequency by ATC—
perhaps with insufficient time for a recovery. How
many ways can you lose your com (and your calm).
Well…

There Must Be 50 Ways…
There must be at least fifty ways to lose communication
and here are just a few:
• misset the aircraft audio panel
• set the aircraft radio volume too low
