HOLDING AIRSPEEDS/ANGLE OF BANK
When an aircraft is 3 minutes or less from the holding fix, and a clearance beyond the fix has not
been received, speed will be reduced such that the aircraft will cross the fix at or below the
maximum holding airspeed. Since holding is a delaying or loitering maneuver until further
clearance is received, an airspeed approximating maximum endurance airspeed is normally flown.
The T-2 NATOPS holding speed is 160 KIAS (approximately 200 KTAS for pattern analysis and
correction purposes). The instructor pilot may choose to hold at a different airspeed. The student
should simply request "Slow to holding speed" when the aircraft is 3 minutes or less from the
holding fix. The deceleration normally takes 5 miles or less. The maximum holding airspeeds for
various holding locations and aircraft vary from time to time. A General Planning document
should be consulted for current limitations on maximum holding speed. The purpose of a
maximum holding airspeed is to ensure that maneuvering aircraft will remain within the assigned
holding air space. All holding turns will be conducted at standard rate or 30 degrees angle of
bank whichever is less. The 2F101 in the NFO mode turns with 30 degrees angle of bank when
gear and flaps are up.
TACAN HOLDING CLEARANCES
Holding clearance may assign a published holding pattern (such as those published on approach
and enroute charts) or issue non-published holding instructions. Holding instructions will always
include the following information, directly or by implication.
1.
Geographic direction of the holding pattern from the holding fix.
2.
Radial and DME of the holding fix.
3.
The holding course.
4.
Pattern leg lengths in NM.
5.
Direction of pattern turns.
6.
Holding altitude.
7.
Expected Further Clearance Time.
3-30
