The RCA2610 Series Digital Horizon is the culmination of 10 years of innovation from RC Allen. The RCA2610 now has a standard display that includes a Digital Slip Indicator and Rate of Turn Indicator. The three-inch RCA2610-3 also comes with an optional Internal Battery Backup. All models come with an NVIS Night Vision filter option. The standard Pitch Sync feature allows pilots to instantly synchronize the airplane symbol to the horizon line when flying in a pitch up or pitch down attitude. We also offer the RCA2610-G which comes without the Pitch-Sync feature. The symbolic airplane is not adjustable. Both versions are available in 3-inch and 2-inch sizes and are designed as a direct replacement for your Electric Attitude Gyro. The RCA2610 is totally self-contained and has no mechanical gyro or special external connections. The screens are highly visible and have adjustable brightness controls. Performance characteristics include full 360 degrees of roll and pitch with a settling error of 1 degree maximum. With no moving parts, the RCA2610 will have a longer lifespan than traditional gyroscopic instruments. The Digital Slip Indicator or the optional Mechanical Slip Indicator (P/N 444-0010-01) can be ordered to satisfy FAA AC91-75.
