NOTE: Glideslope is defined as the descent angle assigned to an approach to a given runway for obstacle
clearance and/or signal reception. Glidepath is defined as the portion of a precision approach that
intercepts the azimuth of an ILS approach or the FAC of a PAR approach.
Both the PAR and ASR approaches are divided into two segments: initial pattern and final approach.
Refer to (Figure 34) for an illustration of the GCA pattern.
During the initial pattern of an ASR or PAR approach, you will be guided by surveillance radar. This
segment includes all maneuvering up to the point at which your aircraft is inbound on the final approach
course and at approximately 8 nm from touchdown. During the transition to final, the GCA controller will
direct your headings and altitudes. All controller instructions to initiate turns and descents should be
complied with immediately. In the pattern, maintain standard rate turns not to exceed 30 degrees AOB.
On final, your AOB should approximate the number of degrees to be turned not to exceed half standard
rate (approximately 10 degrees AOB). A good technique is 30 degrees AOB in pattern, 20 degrees AOB
turning base to final. Once on final, do not exceed 10 degrees AOB for heading corrections to course.
Radar approach minimums can be found in the FLIP instrument approach procedure publications, both on
the approach plates and in the radar approach minimums section (Figure 35). Although some published
approach minimums are lower than 200-1/2, you are limited to absolute minimums of 200-1/2 when single-
