INTERSECTIONS

Amplification An intersection is a point defined by any combination of courses, radials,

or bearings of two or more NAVAIDS. With DME available, an intersection may be identified as

a radial and distance from a station. The station you are using to navigate on the airway is called

the primary station. If a station off the airway is used to identify the intersection, it is called the

secondary station. Intersections are used to help determine the aircraft's position along the

airways.

Identification procedures using either VOR alone, TACAN alone or VOR and TACAN together

are covered here.

Procedure (VOR receiver only) (Figure 617)

Determine your ETA to the intersection.

No later than three to five minutes prior to your ETA, tune and identify the

secondary station and check the position of the VOR needle. Do not change

the course in the IND350 yet.

ii.

If the tail of the needle is not within 10 of the intersection radial:

(a)

Retune the primary station and continue to track.

(b)

Wait a maximum of one minute.

(c)

Retune the secondary station, and once again, check to see if the tail of

the needle is within 10 of the intersection radial.

(d)

Keep repeating until the tail of the needle is within 10 of the intersection

radial.

iii.

If the tail of the needle is within 10 of the intersection radial:

(a)

Set the desired course in the IND350. If passing straight through the

intersection you may set either the radial that makes up the intersection or

its reciprocal, which would be the course to the station. However, if you

are turning at the intersection, you must set the course you desire to fly

after the intersection.
