									           EMERGENCY PROCEDURES PA44-180
GENERAL

      This section provides the recommended procedures for coping
with various emergency or critical situations. All of the emergency
procedures required by the FAA, as well as those necessary for the
operation of the airplane are presented.

        This contains the emergency procedures checklist. They supply
an immediate action sequence to be followed during critical situations
with little emphasis on operation of the systems.

      The amplified emergency procedures corresponding to the
emergency procedures checklist items are found in the Aircraft Flight
Manual (AFM). These amplified procedures contain additional
information to provide the pilot with a more complete description of the
procedures so they may be more easily understood.

      Pilots must familiarize themselves with the procedures in this
section and must be prepared to take the appropriate action should an
emergency situation arise. The procedures are offered as a course of
action for coping with the particular situation or condition described.
They are not a substitute for sound judgment and common sense.

       Most basic emergency procedures are a normal part of pilot
training. The information presented in this section is not intended to
replace that training. The pilot should review standard emergency
procedures periodically to remain proficient in them.

      All emergency procedures outlined in boxes need to be
committed to memory and can be referred to if time permits.
Procedures that are not outlined in boxes should be performed by
reference to the appropriate emergency checklist.
