Aids - FMAs) installed. The high update radar provides near instantaneous position and
altitude information to the FMAs. Automated tracking software provides “monitor
controllers” with aircraft identification, position, altitude, and the predicted position ten
seconds ahead, as well as visual and aural alerts to the controller. This equipment,
trained controllers, an enhanced communications capability that includes a secondary
monitor frequency with tower override, and the ILS equipment collectively make up the
ILS/PRM system.
14.9.3.1. When flying appropriately equipped aircraft and trained as outlined in
AFI 11-202 Volume 3, General Flight Rules and MAJCOM directives, USAF
aircrews are authorized to fly ILS/PRM approaches.
14.9.3.1.1. NOTE: These procedures are also applicable to Simultaneous Offset
Instrument Approaches (SOIA).
14.9.4. Simultaneous close parallel ILS/PRM approaches require a “monitor controller”
using the PRM system be assigned to each runway and to ensure prescribed separation
standards are met. Standard radar and/or vertical separation is used during turn-ons to
final approaches. Vertical separation will continue until reaching an intermediate fix
between ten and fifteen miles from the runway. From this point to the airport, aircraft
may be at the same altitudes, be side by side, or pass traffic on the parallel final approach.
Also from this point, or just outside, a block of airspace has been established as a buffer
between the final approach courses. This airspace is 2,000-foot wide, equal distance from
the finals, and is called the No Transgression Zone (NTZ). The NTZ is shown on the
“monitor controller’s” display and as the name implies, if planes enter or approach the
NTZ, the “monitor controllers” issue instructions to correct the transgression.
