“I then requested, and was given radar vectors to the
nearest airport from ATC. I informed them that the right
engine had been shut down. ATC asked for fuel
remaining and number of souls on board. I was told the
fire crews were standing by. I understood that I was
being given emergency handling and it did not seem
necessary to declare an emergency.”

“At no time was an emergency declared…Upon landing,
we found that the tower controller had of his own volition

10-1-1. EMERGENCY DETERMINATIONS
c. If the words "Mayday" or "Pan-Pan" are not used and you are
in doubt that a situation constitutes an emergency or potential
emergency, handle it as though it were an emergency.
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.

“We received a warning of low oil pressure in the left engine. We
diverted to TXK and declared an emergency with center. Upon
arrival at TXK we were sequenced #2 behind another aircraft on
approach to runway 31. We informed center that we needed to
land on runway 4, as it was longer and straight in. We were told
to execute a left 360 degree turn. We questioned this with
Center, but he said it was necessary for separation. We
reluctantly complied since we did not have a need to land
immediately. I felt that this was not acceptable, as we were an
emergency.”

10-1-3. PROVIDING ASSISTANCE
Provide maximum assistance to aircraft in distress. Enlist the
services of available radar facilities and DF facilities operated by
the FAA, the military services, and the Federal Communications
Commission, as well as their emergency services and facilities,
when the pilot requests or when you deem necessary.
10-1-4. RESPONSIBILITY
a. If you are in communication with an aircraft in distress, handle
the emergency and coordinate and direct the activities of
assisting facilities. Transfer this responsibility to another facility
only when you feel better handling of the emergency will result.

We were given a hold for JFK, we immediately informed
ATC of the need to go now to EWR. After one turn in the
hold we were then vectored away from EWR. I told the
controller I would have to declare an emergency if
needed to get to an airport as only 1 hour of fuel
remained.

“He asked whether I was declaring an emergency...I
mistakenly replied ‘yes’ to his question. Immediately, I
wanted to take that back, but I felt it was too late, and
probably not even possible, to rescind the emergency
declaration, so I accepted the clearance to land at BWG.
I never intended to declare an emergency, and I did not
need to declare an emergency because I could have
landed at Nashville. This was an inadvertent mistake.”

Declaring An Emergency – Fact and Fiction
A non instrument rated pilot inadvertently flies into IMC.
He radios ATC, declares an emergency, and asks for a
vector to the nearest visual conditions. Upon reaching
VMC he makes the reasonable assumption that the
conditions can be maintained for the remainder of the
flight

Declaring An Emergency – Fact and Fiction
The passengers health in doubt, we decided to ask for
priority handling into DAL. We did not declare an
emergency to circumvent the FAR’s, only asking for and
receiving full cooperation from all controllers. During the
process we exceeded 250 kias below 10,000’…The
reason this report is being written is because the FAA is
‘not here to help me’”.
Reporter states on callback “He will never declare an
emergency if any way around it.”

Air Safety Inspector Comments
“…an intent of 91.3 is to ensure the PIC will handle the
emergency in a manner necessary to save lives and not
be worried about regulatory compliance.”
“I’ve never seen a pilot violated for deviating from a
regulation when that pilot has either declared an
emergency OR has stipulated in ANY written response to
the FAA that an emergency existed at the time of the
deviation.”
Emergency and Abnormal Situations Project
Fiction
•The legal consequences of declaring an emergency include
extensive paperwork and a probable violation
Fact
•A pilot may have to file a written report of deviation during an
emergency situation only if one occurs
•The regulations provide immunity from any deviation committed
during an emergency in the interest of safety
•The FAA supports the pilots ability and judgment to act in this
manner

The Facts
•Pilots, Dispatchers, Airline Management, and ATC can
declare an emergency
•A controller will provide the maximum amount of assistance
they deem necessary. However, a pilot may request more or
less assistance in the interest of safety.
•Legally, a pilot MAY have to file a written report of an
emergency in the event of a deviation from a published
regulation, and they will not face an FAA violation if their
actions are in the interest of safety
