Can a Heads-Up Display Help You Fly Safer Approaches?
The approach phase of flight requires a lot of concentration and there are many opportunities for mistakes to occur. Shallow approaches, coming in too fast or slow, running off the end the runway or even landing on the wrong runway can easily happen. The GRT Heads-Up Display provides valuable information, guidance and warnings without having to look down at a PFD and then re-focus your vision, read the display, look back out the window and re-focus your eyes again. The most important flight data is continually before your eyes as you look out the window along your approach path.
In many ways, the Heads-Up Display obsoletes traditional panel mounted instrumentation, providing a more natural way to stay aware of your approach. Lets take you through a typical approach…
Airspeed – Rotating digits on the left side of HUD show your airspeed, and rate-of-change of airspeed while your head is outside the cockpit. You remain aware where the outside world is going. This is backed up with AOA warnings via a pitch limit indicator, right on your HUD.
Course Capture – Waypoint sequencing that requires capturing a new course (magenta line) couldn’t be more simple. The HUD enlarges its HSI and centers it on the screen. Precise projected paths are provided for a standard rate turn, and your current turn, accounting for winds, speed, and bank angles.
Runway Location – Where is the runway? The HUD outlines the runway edges. Even the experienced pilot will appreciate being shown the runway.
Runway Identification – Automatic identification of the airport and runway you are approaching. No pilot input. No confusion with parallel runways. No chance of error.
Automatic HITS for all runways – Highway-in-the-sky guidance puts you on path to a safe touchdown. Completely automatic, and user configurable. Flight director commands are also provided on the HUD.
Low Approach Warning – A shallow approach is an all too common cause of accidents. The ability to alert you to this all the way to the threshold is not possible with conventional cockpit-mounted instrumentation. Standard and completely automatic with the HUD.
Runway Overrun Warning – As you descend to within 250 feet of the runway, your path and speed are used to predict how much runway your approach will use. Warnings make overruns obvious before they happen, and your alerts are provided when your own personal margins are compromised. Here the OVERRUN indication is shown also, with a prediction of 100 feet of overrun.
Runway Length Message – The RWY Length message is warning the pilot that only 200 feet of runway will remain based on the current flight path and speed.
