AW169 SYSTEM NOTES

Weather Radar RTA-4112
Modes, ranges, controls, and the one hard limitation on what this radar is allowed to be used for.
Weather Radar RDR-1600
A separate, optional maritime/SAR radar kit — the one with the SR1/SR2/SR3 surface-search modes, beacon detection, and its own tighter ground-transmission distance.
TCAS II: Traffic Advisory System
How Traffic Advisories and Resolution Advisories actually work, the exact power/airspeed technique for each RA, and every inhibit altitude.
HTAWS: Terrain Awareness and Warning
FLTA and GPWS, and every alert and what triggers it — the onshore-only baseline version of this system.
Synthetic Vision System (SVS)
A 3D terrain picture on the PFD — what it's built from, when it turns itself off, and the one rule about attitude.
Digital Map System
A moving-map underlay for the MFD — small system, but nine distinct failure messages worth being able to tell apart.
OPLS: Obstacle Proximity LiDAR System
Three LiDAR units, a 360° ring of distance awareness in one plane only, and the color/sound logic that goes with it.
EVS Camera
An infrared nose camera for reduced visibility — what it shows, what it doesn't, and why it fights the SVS for screen time.
EHPS: Electric Motor-Driven Hydraulic Power Supply
A ground-only electric hydraulic pump that changes the order you're allowed to do things in — why it lets engine 1 start straight into MAIN mode.
ADI STBY Emergency Battery
30 minutes of backup power for one instrument, and the three-position switch that controls it.
External Hoist Operations (Goodrich)
The rescue hoist system — weight and airspeed limits, the two cable-cutter systems, and how engine failure in the hover changes with a load on the hook.
Cargo Hook Operations
Electrical, mechanical, and explosive-cartridge release — three independent ways to let go of an external load, and when each one applies.
Ditching Configurations
The emergency floatation system and liferafts — arming logic, the full water-contact sequence, and what FLOAT DEGR actually means.
ADELT: Crash Position Indicator with Deployable ELT
Two frequencies, two purposes — the swept tone that just says "here" and the digital message that says "here, precisely, from GPS."
EAPS: Engine Air Particle Separator
How the vortex separator protects the P&WC 210A from sand and dust, and the engine limits table that only applies with this kit installed.
Fuel Transfer Pump
Why a failed engine's own fuel becomes usable again, and the one-way rule that keeps a pilot from ever feeding the wrong tank.
RNP APCH with LPV/LP Minima
A satellite-augmented approach down to a 200 ft decision height — the annunciation colors, the 900 fpm/900-to-1000-ft rule for a failure, and when a missed approach becomes mandatory.
