Terminal Procedures booklets. Reasonable buffers
are provided for normal maneuvers. However, no
consideration is given to an abnormally early turn.
Therefore, when an early missed approach is
executed, pilots should, unless otherwise cleared by
ATC, fly the IAP as specified on the approach plate
to the missed approach point at or above the MDA or
DH before executing a turning maneuver.
26.3 If visual reference is lost while circling to land
from an instrument approach, the missed approach
specified for that particular procedure must be
followed (unless an alternate missed approach
procedure is specified by ATC). To become
established on the prescribed missed approach
course, the pilot should make an initial climbing turn
toward the landing runway and continue the turn until
established on the missed approach course. Inasmuch
as the circling maneuver may be accomplished in
more than one direction, different patterns will be
required to become established on the prescribed
missed approach course depending on the aircraft
position at the time visual reference is lost.
Adherence to the procedure will help assure that an
aircraft will remain laterally within the circling and
missed approach obstruction clearance areas. Refer
to paragraph 26.8 concerning vertical obstruction
clearance when starting a missed approach at other
than the MAP. (See FIG ENR 1.5−31.)

26.4 At locations where ATC radar service is
provided, the pilot should conform to radar vectors
when provided by ATC in lieu of the published
missed approach procedure.
26.5 Some locations may have a preplanned
alternate missed approach procedure for use in the
event the primary NAVAID used for the missed
approach procedure is unavailable. To avoid
confusion, the alternate missed approach instructions
are not published on the chart. However, the alternate
missed approach holding pattern will be depicted on
the instrument approach chart for pilot situational
awareness and to assist ATC by not having to issue
detailed holding instructions. The alternate missed
approach may be based on NAVAIDs not used in the
approach procedure or the primary missed approach.
When the alternate missed approach procedure is
implemented by NOTAM, it becomes a mandatory
part of the procedure. The NOTAM will specify both
the textual instructions and any additional equipment
requirements necessary to complete the procedure.
Air traffic may also issue instructions for the alternate
missed approach when necessary, such as when the
primary missed approach NAVAID fails during the
approach. Pilots may reject an ATC clearance for an
alternate missed approach that requires equipment
not necessary for the published approach procedure
when the alternate missed approach is issued after
beginning the approach. However, when the alternate
missed approach is issued prior to beginning the
approach the pilot must either accept the entire
procedure (including the alternate missed approach),
request a different approach procedure, or coordinate
with ATC for alternative action to be taken, i.e.,
proceed to an alternate airport, etc.
26.6 When the approach has been missed, request a
clearance for specific action; i.e., to alternative
