The Model 6600-NG is a 3-channel system designed to test aircraft equipped with SmartProbes™. The tester has one Static output (Ps1), one Pitot output (Pt) and a third output (Ps2) which can be used to simulate either AOA (angle of attack) or AOS (angle of sideslip). It is used to perform leak checks and RVSM accuracy checks on the Pitot-Static systems – including altimeters, airspeed indicators and VSI’s – and can be done at low airspeeds. The Model 6600-NG includes a Remote unit with large keypad and display, a removable 8-hour battery (optional), wide operating temperature (optional), and “profiles” to accelerate testing. The unit can be controlled by an iPad or other tablets.
