considered.
As a guide, the approach briefing should include at least the following:
• weather and NOTAMS at destination and alternate, as applicable
• type of approach and the validity of the charts to be used
• navigation and communication frequencies to be used
• minimum safe sector altitudes for that airport
• approach procedure including courses and heading
• vertical profile including all minimum altitudes, crossing altitudes and
approach minimums
• determination of the Missed Approach Point (MAP) and the missed
approach procedure
• other related crew actions such as tuning of radios, setting of course
information, or other special requirements
• taxi routing to parking
• any appropriate information related to a non-normal procedure
• management of AFDS.
Approach Category
FAA Category Speed
C 121 knots or more but less than 141 knots
D 141 knots or more but less than 166 knots
Speed - based upon a speed of VREF in the landing configuration at
maximum certificated landing weight.

FCT 767 (TM) 5.3
The 767 is classified as a Category “C” or “D” airplane, depending upon
maximum landing weight, for straight in approaches. For circling approaches use
the minima associated with the anticipated circling speed.
Approach Clearance
When cleared for an approach and on a published segment of that approach, the
pilot is authorized to descend to the minimum altitude for that segment. When
cleared for an approach and not on a published segment of the approach, maintain
assigned altitude until crossing the initial approach fix or established on a
published segment of that approach. If established in a holding pattern at the final
approach fix, the pilot is authorized to descend to the procedure turn altitude when
cleared for the approach.
If using a VNAV path, all altitude and speed constraints must be entered either
manually, by selecting a published arrival, or by a combination of both. When
properly entered, the VNAV path profile complies with all altitude constraints.
Crossing altitudes may be higher than the minimum altitudes for that segment
because the VNAV path is designed to optimize descent profiles.
When conducting an instrument approach from the holding pattern, continue on
the same pattern as holding, extend flaps to 5 on the outbound track parallel to
final approach course. Turn inbound on the procedure turn heading. This type of
approach is also referred to as a race track approach.
Procedure Turn
On most approaches the procedure turn must be completed within specified limits,
such as within 10 NM of the procedure turn fix or beacon. The FMC depicted
procedure turn, or holding pattern in lieu of procedure turn, complies with airspace
limits. The published procedure turn altitudes are normally minimum altitudes.
The procedure turn size is determined by the ground speed at the IAF.

5.4 FCT 767 (TM)
Adjust time outbound for airspeed, wind effects, and location of the procedure
turn fix. If the procedure turn fix is crossed at an excessively high ground speed,
the procedure turn protected airspace may be exceeded. The procedure turn should
be monitored using the map to assure the airplane remains within protected
airspace.
Stabilized Approach Recommendations
Maintaining a stable speed, descent rate, and vertical/lateral flight path in landing
configuration is commonly referred to as the stabilized approach concept.
Any significant deviation from planned flight path, airspeed, or descent rate
should be announced. The decision to execute a go-around is no indication of poor
performance.
Note: Do not attempt to land from an unstable approach.
