139 Automatic Ignition System
Provides automatic ignition for both engines in case of engine flameout during takeoff and landing on wet runways and during flights in icing conditions. Automatic ignition is not limited to only these conditions; it is available anytime the engine RPM is above 60 percent. Models 680T, 680V, 680W, 681, 690, 690A, 690B.
137 Windshield Antifog System
Eliminates internal fogging of windshields and subsequent moisture problems. The gold-tinted heat film also acts as a sunscreen. Models 690, 690A, 690B, 690C, 690D, 695, 695A, 695B.
136 Improved Tail Light/Strobe Light Assembly

135 Aural Mach Overspeed Warning System
Provides a fully automatic airspeed monitoring system, which, because of the low drag feature that allows the Commander jet props to easily increase airspeed during let down, has introduced the added safety feature of an aural warning in the event of an inadvertent overspeed of the airplane. The sensing switch is pre-set to aurally alert the pilot of airspeeds exceeding 243 KIAS. Models 690, 690A, 690B, 690C, 695.
