B.When taking off on the runway with incomplete or inaccurate terrain data, the crew can inhibit the switch TERR press (located in terrain selection GPWS control panel) to the "OFF" (white OFF light on)to avoid fake terrain warning alarms. When making the first turn off after takeoff or entering the instrument meteorological conditions(whichever come first), press TERR switch again to shadow the white OFF light for a restart of terrain warning system.
C.When making an approach on the runway with incomplete or inaccurate terrain data, the crew should switch Inhibit TERR button (terrain located in GPWS control panel) to the "OFF" position(white OFF light on) to avoid any fake terrain warning alarms during approach.
D.When making an approach on the runway with incomplete or inaccurate terrain data, the crew switches Inhibit TERR to "OFF" as required, and press it again after landing to restart the terrain warning system.
