Aircraft Operations

I-6-1-2
Procedures — Aircraft Operations — Volume I
1.3.4 Start of outbound timing
Outbound timing begins over or abeam the fix, whichever occurs later. If the abeam position cannot be determined,
start timing when the turn to outbound is completed.
1.3.5 Outbound leg length based on a DME distance
If the outbound leg length is based on a DME distance, then the outbound leg terminates as soon as the limiting DME
distance is reached.
1.3.6 Limiting radials
1.3.6.1 In the case of holding away from the station (see Figure I-6-1-1 C), where the distance from the holding
fix to the VOR/DME station is short, a limiting radial may be specified. A limiting radial may also be specified where
airspace conservation is essential.
1.3.6.2 If the limiting radial is reached before the limiting DME distance, this radial should be followed until a
turn inbound is initiated. The turn should be initiated at the latest where the limiting DME distance is reached.
1.3.7 ATC notification
If for any reason a pilot is unable to conform to the procedures for normal conditions, air traffic control should be
advised as early as possible.
1.4 ENTRY
Note.— Variations of the basic procedure for local conditions may be authorized by States after appropriate
consultation with the operators concerned.
1.4.1 The entry into the holding pattern shall be according to heading in relation to the three entry sectors shown
in Figure I-6-1-2, recognizing a zone of flexibility of 5° on either side of the sector boundaries.
1.4.2 For holding on a VOR intersection, the entry track is limited to the radials forming the intersection.
1.4.3 For holding on a VOR/DME fix, the entry track is limited to:
a) the VOR radial;
b) the DME arc; or
Note.— A DME arc entry procedure is specified only when there is a specific operational difficulty which
makes the use of other entry procedures impossible.
c) the entry radial to a VOR/DME fix at the end of the outbound leg, as published.
