3. When the approach procedure involves a
procedure turn, a maximum speed of not greater than
200 knots (IAS) should be observed from first
overheading the course reversal IAF through the
procedure turn maneuver to ensure containment
within the obstruction clearance area. Pilots should
begin the outbound turn immediately after passing
the procedure turn fix. The procedure turn maneuver
must be executed within the distance specified in the
profile view. The normal procedure turn distance is
10 miles. This may be reduced to a minimum of
5 miles where only Category A or helicopter aircraft
are to be operated or increased to as much as 15 miles
to accommodate high performance aircraft.

reversal. The teardrop procedure consists of
departure from an initial approach fix on an outbound
course followed by a turn toward and intercepting the
inbound course at or prior to the intermediate fix or
point. Its purpose is to permit an aircraft to reverse
direction and lose considerable altitude within
reasonably limited airspace. Where no fix is available
to mark the beginning of the intermediate segment, it
must be assumed to commence at a point 10 miles
prior to the final approach fix. When the facility is
located on the airport, an aircraft is considered to be
on final approach upon completion of the penetration
turn. However, the final approach segment begins on
the final approach course 10 miles from the facility.

4. A teardrop procedure or penetration turn may
be specified in some procedures for a required course

5. A holding pattern in lieu of procedure turn
may be specified for course reversal in some
