Sandel Avionics has new 4x4-in. EHSI and EADI displays which
provide operators of turbine-class aircraft with a modular technology update
for aging electromechanical units. By incorporating the company's SandelSmart
I/O, operators can install the SN4500 and SA4500 in practically any analog or
digital aircraft. The units can be used for moving map displays and highly
readable attitude displays. The EHSI and EADI can be installed separately or in
tandem. An SN4500 EHSI is shown.
