CHAPTER FIVE
Examples:
"In one minute, there is a 500 foot tower two miles left of course."
"In 45 seconds, there will be a small airfield 2 NM left of course."
"Bird, 12 o'clock, high" or "Bird, on the nose, level."
"In two minutes, NAV-3 will be crossing from right to left."
Route Exit
After the target, initiate a HATT brief calling for a climb to an appropriate VFR altitude.
Maintain VMC but plan to coordinate an "IFR pickup" (IFR clearance) for the arrival routing and
approaches required to complete the event. If weather is a factor, maintain VMC until receiving
your IFR clearance. Once IFR, transition to an instrument scan and follow all normal INAV
procedures to prepare for and fly the approaches. Make sure to remain clear of any class A, B, C,
or D airspace until you have the appropriate clearances to enter. In general, leaving the route you
will:
1.
Climb to appropriate VFR altitude and maintain VFR.
2.
Tune NAVAIDS and get ATIS, if available.
3.
Contact controlling agency and pick up an IFR clearance.
4.
Comply with INAV FTI procedures for the remainder of the sortie.

TURNPOINT PROCEDURES
This section gives an example of how a normal turnpoint will progress. The computation tools to
come up with the given solutions are presented later in the chapter. Read the following and then
refer back to this section as you progress through the rest of the chapter. Presenting the
information in this manner provides a better context for how and when to apply the various
computation tools you will learn. The underlined items in each call below refer to an expanded
explanation in the Notes section following the sample dialogue. This example was generated with
an initial course of 360, winds 310/15, outbound course of 305, base airspeed of 180 knots
(prior to the turnpoint, the airplane was on a compensated heading of 356 and a compensated
airspeed of 190 KIAS). See Figure 5-3.
2 Minute Prior Call
1.
"Two minutes prior to Delta" (Note 1)
