The iSFD, or integrated secondary flight display, system from Meggitt Avionics is an update of the company’s SFD. The updated system, aimed at use in commercial and military fixed- and rotary-wing aircraft, displays critical flight information – attitude, altitude and airspeed – replacing two or three electromechanical cockpit standby instruments with a single 3-ATI-size display unit. The active matrix liquid crystal display (AMLCD) has an LED backlight and is compatible with other updated AMLCD primary flight displays.
Within the iSFD itself are solid-state sensors plus a micro-processor system measuring aircraft pitch, bank attitudes, and air data. Air data is measured using the internal air data module (ADM); alternatively, if measured air data are available from an aircraft multifunction probe (MFP) or air data computer (ADC), the iSFD can receive and process the available digitally transmitted air data. If digital magnetic heading data is available, the iSFD will also display aircraft magnetic heading. Its small size – a display area of 61 x 61 mm – and light weight – the entire system weighs 3.3 pounds – are meant to facilitate installation in aircraft. As the system has no International Traffic in Arms Regulations (ITAR) components, it is available for export.
