Note 2.— Entries on DME arcs should only be designed if there is a specific operational difficulty which makes the
use of other entry procedures impossible.
Note 3.— Entry procedures from other navigation facilities may require additional protected airspace.

1.4.5
In calculations of the VOR cone effect area and DME slant range conversions, the height above the facility (hl) is to be
used (see Appendix A to this Chapter, 6.4 and 6.5).
1.5 PROMULGATION
1.5.1 Special VOR/DME holding entry procedure
1.5.1.1 For entry into a VOR/DME holding pattern an entry radial to a secondary fix at the end of the outbound
leg may be established (see Figure II-4-1-3 a) and b)). In this case Sector 1 and Sector 2 entries are not authorized.
1.5.1.2 The holding pattern will be entered directly along the entry radial or by the Sector 3 entry procedure.
Having reached the secondary fix, the aircraft will turn right and follow the holding pattern. In this case the entry radial
shall be published and clearly depicted.
1.5.2 Airspeeds
1.5.2.1 The speeds upon which the holding area is based should be published.
1.5.2.2 Slant range distances for VOR/DME holding
1.5.2.2.1 The distance of holding fix and the limiting outbound distance shall be expressed in whole kilometres
(nautical miles) as the slant-range from the DME station.
1.5.2.2.2 Slant-range distances together with the limiting radial (where specified), shall be published on the
appropriate aeronautical chart to be used by the pilot.
