<![CDATA[Terrain display on vintage aircraft]]>In areas of high terrain, I see the TAWS provides " Look-ahead terrain and display alert" - but am I to understand this is only for excessive terrain closure? Did the aircraft use the ground mapping function of the radar as a sort of terrain feature on the EHSI?

The aircraft doesn't have a 'terrain radar' as such, so it uses the weather radar to detect any terrain surrounding the aircraft.
