Regarding “A way to mask those call outs on climb out”, our system detect Go-Around and will not make any announcements. Further, In the case of AGL height announcements, we can enable only the required heights. For example, if only 400, 300, 100, 50, and 10 feet are needed, the system will call out only these specific heights.

In order for the gear detection to work, the SkyVoice Alert LHA 500 uses a sensor wire to detect the presence or absence of voltage on the gear position indicator circuit. If the aircraft has separate indicator lights (e.g., a Green light for "gear down and locked" and a Red/Amber light for "gear up and locked"), the sensor wire can be connected to either. The corresponding detection method must then be selected in the SkyVoice Alert LHA 500 software based on where it is connected.

For pilots navigating the skies, situational awareness is paramount, especially during critical phases like takeoff and landing. Holy Micro! LLC’s SkyVoice Alert 500 (Model: LHA-500-A) is a game-changing, NORSEE-certified device designed to enhance safety by providing real-time audio height announcements and critical reminders. Whether you’re flying a pressurized, certified, or experimental aircraft, this compact system integrates seamlessly to support better decision-making. Here’s why the SkyVoice Alert 500 is a must-have for general aviation pilots. What is the SkyVoice Alert 500? The SkyVoice Alert 500 is an FAA Approved system that uses advanced LiDAR technology to measure height above ground level (AGL) with ±1% accuracy, up to 590 feet. It delivers audio announcements through your headset—via wired connection or Bluetooth—alerting you to predefined heights, landing gear warning, and other reminders. Certified under FAA’s NORSEE. It can be used in all aircraft (pressurized, certified and experimental). Key Features and Benefits LiDAR-Powered Precision Utilizing a built-in LiDAR (Laser) with eye-safe Class 1 Laser module for measurements, an accuracy of ±1% (distance to ground/objects) is achieved. Announces heights like 500, 400, 300, 200, 100, 70, 50, 20, 10, 5, 2, and 1 foot during takeoff, landing, or go-around, helping pilot’s master depth perception. A hard surface such as Tarmac, Asphalt, and Concrete runways, along with turf/grass or dirt strip are suitable for range reading. (not approved for use over water or if the runway has a water level of 3 inch or more.). Customizable Audio Alerts Choose between male (“Frank”) or female (“Lisa”) voices for clear, professional announcements. Reminders that can be set are “Clearance, Check Gear, Checklist, Speed, Flaps, Pump, LC GUMPS and Prop”. Only one Reminder per Height is allowed and no reminder below 100. Adjustable volume and power-on announcements (e.g., “SkyVoice Alert 500 Ready” at 0, 30, 60, or 90 seconds) ensure compatibility with your audio panel or Bluetooth headset. Advanced Safety Features Landing Gear Warning: Detects gear position (up/down) using an isolated optical sensor, announcing “Check Gear” every 2 seconds (adjustable) if gear is up below 560 feet AGL. GPS Integration: Connects to GPS via RS-232 to announce altitudes from 18,000 to 500 feet MSL Run Time Reminders: Alerts for “Check Tank” (The user can set a value from any of the listed time interval viz. 30 min, 45 min, 60 min and 90 min) and “Check Fuel” (The user can set a value from any of the listed time interval viz. 1 hr, 1.5 hr, 2 hr, 2.5 hr, 3 hr, 3.5 hr and 4 hr) to maintain fuel awareness. Go-Around Detection: Recognizes Go-Arounds based on height thresholds (default: 400 feet start, 100 feet climb) to resume relevant callouts. Once Go-Around is detected, SkyVoice Alert 500 will announce the already announced higher altitudes only after the device goes out of range and time entered is elapsed.

The normal retail price for our entire Absolute AoA system is under $2000. It includes a mast/probe that can be installed on any inspection plate located under the wing, in front of the flap. The tubes from the probe connect to sensor electronics mounted directly above the inspection plate. Additionally, there is a processor unit that can be installed behind the instrument panel. The connection between the sensor electronics and the processor can be either wired or wireless, and the display is linked to the processor. For setup and calibration, the Absolute AoA system comes with a digital HMI (Human-Machine Interface), similar in size to a 6.5-inch phone. This device is used to connect to the system and perform calibration. The Absolute AoA system offers a variety of display size options, ranging from 3.5 inches to 2.4 inches, including bar-style displays. These digital displays feature touch functionality, allowing you to adjust settings and choose your preferred AoA presentation style. The most important feature of our Absolute AoA system is its normalized pressure system, which ensures highly accurate and consistent readings across all phases of flight. Unlike traditional pressure differential systems, ours is a ratio-based system that uses multiple sensors. Pressure differential systems are only reliable near the stall speed they were calibrated for. Outside of that range, especially under varying loading, density altitude conditions and flap, they become non-linear and inaccurate. While the FAA only requires that an AoA system's stall warning activate before the aircraft's built-in stall warning, our system goes far beyond that. It allows you to accurately fly all your V speeds (Vx, Vy, Va, Best Glide, etc.) regardless of density altitude or loading conditions. When flaps are deployed, the wing's chord length, area, and camber change, increasing lift, altering pitch, shifting the center of pressure, and reducing stall speed. If these factors are not accounted for, AoA readings become inaccurate. Our Absolute AoA system automatically detects flap position without requiring any physical connection to the flap system or internal wiring. This is achieved through LiDAR technology integrated into the probe, which monitors and detects flap position. This ensures accurate AoA readings during approach, even with flaps and gear extended. Again, this is a normalized pressure ratio system, not a pressure differential system. Pressure differential systems are essentially limited to stall warnings and are not linear across the entire flight envelope. To calibrate our system, you must fly at the correct speeds for the current density altitude and loading conditions. Before the calibration flight, you will need to calculate the appropriate speeds for each AoA you intend to fly (e.g., Vx, Vy, Va, Best Glide). Once calibrated, the system provides precise AoA indications tailored to the present loading and density conditions. This is the key difference that sets our system apart.

Say goodbye to limitations and hello to precision. In response to the FAA's Special Airworthiness Information Bulletin (SAIB: 2024-07), Holy Micro! LLC presents the Absolute AoA System, a next-generation solution designed to provide accurate Angle of Attack (AoA) data for all phases of flight. Why Absolute AoA?
