Procedure (Two NAV Receivers)

CHAPTER SEVEN

T-34C INSTRUMENTS

Primary NAVAID/Radial: The NAVAID and radial from that NAVAID upon

which the holding pattern is oriented.

ii.

Secondary NAVAID/Radial: The NAVAID and radial from that NAVAID

which defines the holding fix (intersection) on the primary radial. (Figure 72)

Using normal Intersection procedures identify STUDY intersection. If you are flying

direct PointtoPoint to the intersection you will probably intercept the primary or

secondary radial prior to arriving at the intersection (unless your tracking was perfect).

In either case, the Holding Entry procedures are dependent upon the reciprocal of the

holding course at the time you cross the fix.

Figure 72 Study Intersection

When holding at a VOR station the reciprocal of the holding course is always the same as

the radial. At an intersection, however, this will only be true when the holding pattern is

oriented so that the inbound leg is toward the station. Holding is always inbound to a fix.

When that fix is an intersection, the inbound holding course could possibly be away from

the station. Inbound to the holding fix does not necessarily mean inbound to the

NAVAID.

Figure 72 depicts STUDY intersection, which is located at the crossing point of V200 (TUR 90R)

and V100 (WHI 360R). There are four possible holding patterns at STUDY located along V200.

In patterns A and B, the holding course 90 and the holding radial are the same. There are four

additional holding patterns, which could be located at STUDY. They would be North and South of

STUDY on V100.

Procedure (TWO NAV RECEIVERS)

Intersection Holding can be accomplished with one or two navigation receivers (VOR

and TACAN). This discussion will refer to a specific example in which two NAV

receivers are used. (Figure 7-3)
