CHAPTER SIX CH 4
On different approaches the transition at the IAF could involve a
descent and/or a reduction in airspeed.
TWIST Ensure the inbound course (124º) is set in the IND350; intercept the
course inbound. If already established on the arc, set the final approach course in
vi. TALK Give the appropriate voice report if required.
Using the proper lead point, turn to intercept and maintain the arc. This step may
occur before the above steps are completed. Once established on the arc twist in the
final approach course (211º).
When within 5NM of FAF make a level or descending transition to BAC.
Anticipate interception of the final approach course referencing the tail of the
TACAN needle and the CDI while on the arc. Remember, the turn onto final
approach course is a 90º intercept.
On some approach charts a published lead radial (designated "LR
XXX") is provided as an advisory point for turning onto the
inbound course. These designated lead radials are based on the
performance of the aircraft for which the approach was designed.
For instance, at Eglin AFB, the approaches and lead radials were
designed with the performance of the F15 in mind. For this
reason, published lead radials shall not be used in the T34C. The
pilot may elect to calculate the lead radial based on airspeed and
distance from the NAVAID.
Once established inbound comply with the remainder of the Low Altitude
Instrument Approach Procedures (paragraph 623).
Overshooting the arc or final approach course due to insufficient lead or slow scan
Failure to descend to minimum altitudes for the various approach segments.
Remember to refer to the profile view.
