Instrument Flight
Flight Procedures
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.
