File Description: Upgrade package for the popular Richard Probst v4 B727-200 panel (rp727pn4.zip). The new gauge set fixes some bugs in the original panel (see readme text for details). Also included are 4 unique and all-new, XML gauge tables that provide pilots with takeoff, climb, cruise, descent, and landing V-ref speeds - everything you need to know to realistically fly the B727-200. The XML gauges look like paper charts, similar to what actual B727-200 pilots use. User manual for the XML gauge tables included in MS Word format. Easy installation. Gauge fix by Richard Probst, XML gauge set by Charles Fox.
