Procedure (One NAV Receiver)

T-34C INSTRUMENTS

CHAPTER SEVEN

Update correction orbits based on the data from previous orbits. Remember, your

displacement from the station will make precise wind corrections more difficult at an

intersection.

Continue to monitor the time. Be sure to update to the EFC time five minutes prior to the

EFC time.

When cleared out of Intersection Holding, you may turn direct to the intersection and

begin an immediate acceleration to cruise airspeed.

Procedure (ONE NAV RECEIVER)

Using the same example:

Intersection Holding using one NAVAID is very similar to Intersection Holding using

two NAVAIDS. However, in this case, you will be using a single NAV receiver to

monitor both the primary and secondary NAVAIDS.

Three to five minutes prior to reaching the holding intersection ensure the secondary

NAVAID is tuned and identified to check your position.

Your entry turn is determined in the same manner as any other holding pattern. At the

intersection (when the CDI centers), perform the 6 Ts. When established wings level

on the outbound heading, begin timing for one minute and ensure the primary

NAVAID is tuned and identified, twist in the holding course (90) in the CDI, and

check the VOR/TACAN switch in the appropriate position.

At the completion of one minute outbound timing, turn to intercept the holding radial

inbound to STUDY. Remember, a large intercept angle may be required to establish

the aircraft on the holding radial inbound to STUDY intersection. Once an intercept is

established inbound to STUDY intersection, prepare to identify the intersection.

Tuning the secondary NAVAID, setting the VOR/TACAN switch to the appropriate

position and setting the CDI to a course to identify the intersection should be

completed no later than 30 seconds after rolling wings level inbound to the

intersection. Hold heading carefully, as you will not have the advantage of tracking

inbound to the intersection using the tail of a needle.

At STUDY intersection, commence the NOWIND orbit. Once wings level on the

outbound heading (270), begin timing for one minute. Retune and identify the

primary NAVAID and twist the holding course (90) in the CDI.

At the completion of your oneminute outbound timing, turn to intercept the holding

radial inbound to STUDY. TAILRADIALTURN.

Start timing as you roll wings level (with an intercept set or on course) and determine

wind direction. TAILRADIALWIND.
