This package contains a custom autopilot and two GCA (Ground Controlled Approach) gauges: Approach Pattern Control (APC) and Precision Approach Radar (PAR). You can request Pattern Control from 15 to 30 miles out, and the Approach Controller will set you up for a downwind, dogleg, or straight-in approach leading to a point eight miles from the runway at the proper altitude for a 3-degree glideslope. At the intercept point, the PAR Controller will take over and talk you down to the runway threshold. The GCA and PAR processes can be run in auto or in manual mode; that is, the panels can be visible or hidden and autopilot assistance can be turned on or off. As a consequence, serious realism challenges are possible, including hands-on approaches flown in proverbial pea- soup weather. The project is hugely indebted to Karol Chlebowski's powerful AILA (Airborne Instrument Landing Approach) gauge, adapted by permission of the author, and Doug Dawson's equally powerful sound DLL gauge. GCA gauges and manual by Manfred Jahn, historical research by Tom Harnish and compatibility testing by Ralf Scholten.
