International Aviation Services (IASL) is undertaking a major overhaul and upgrade of an ex-airline Boeing 747SP for an undisclosed Middle-Eastern head-of-state customer. The work includes the installation of a five-tube Honeywell EFIS-85 electronic flight instrumentation system (EFIS), dual navigation-management systems, dual global-positioning system and satellite communications. The supplemental type certificate for the avionics upgrade is expected in mid-1997.
