Grob’s SPn, a carbon-fiber light business twinjet introduced at last month’s Paris Air Show, will enter production with the Honeywell Apex avionics system, according to officials from the German company.

The $7.1 million “utility jet” (see also page 1) will feature a four-display version of Apex that includes a pair of 15-inch primary flight displays flanking two vertically stacked 10-inch multifunction displays. According to the aircraft builder, TCAS II, EGPWS and dual FMS will be standard. Grob surprised almost everybody at Paris by bringing a flyable prototype of the airplane to Le Bourget for the show.

Honeywell’s Apex avionics system, referred to internally as the “son of Primus Epic,” appears to be a highly capable cockpit, but it has failed to attract the interest of many airframe OEMs, as certified systems from Avidyne, Garmin and Rockwell Collins have so far taken the lion’s share of business in the light jet and very light jet market segments.
