h.
Cleared out of holding.
i.
It is very important to listen to your approach clearance once established in
holding. If established in a published holding pattern and subsequently cleared
for the Holding Pattern Approach, you may commence the approach from
within the holding pattern and descend to the IAF altitude (Figure 638). If
established in a holding pattern and subsequently cleared for an approach other
than a Holding Pattern Approach, you must maintain last assigned altitude or
the published minimum holding altitude, whichever is lower, until established
on a segment of the approach (Figure 642).
ii.
Airspeed when departing holding is at pilot's discretion. Use good judgment
and determine if it is more appropriate to maintain slow cruise or transition to
normal cruise. This decision should be based on your intentions departing
holding (continue enroute or commence an approach) and the aircraft position
in relation to the instrument approach (if conducting an approach from
holding).

Common Errors
a.
Doing an overthestation intercept to intercept the holding radial outbound.
Remember, the outbound leg in the holding pattern is a heading to fly.
b.
Twisting in the reciprocal vice the course.
c.
Starting the outbound leg timing when the wings roll level vice when the wings roll
level or abeam the station, whichever occurs last.
d.
Misinterpreting wind direction through disorientation, improper use of the Tail
RadialWind method, or using a HeadRadialWind method.
e.
Attempting to correct for crosswind by shallowing or steepening the turn inbound.
This technique may work, but it leads to sloppy Basic Instrument airwork, and
should not be practiced.
f.
Not intercepting the holding course on each orbit. If the aircraft is not established on
the holding course at station passage, the wind corrections you have determined will
not be accurate.
g.
Using an insufficient intercept angle to acquire the inbound course.
h.
Not holding StandardRate Turn and constant airspeed (slow cruise) during all turns.
Impossible to correct for winds, if airwork is not consistent throughout the orbit.

HOLDING DURING ADVERSE WIND CONDITIONS
It is not unusual for winds aloft to attain velocities in excess of 20 knots. In these circumstances,
