Garmin® Brings Safety Enhancing Electronic Stability and Protection To G3X™ And G3X Touch Systems That Utilize Garmin Autopilot
Garmin International Inc., a unit of Garmin Ltd. (NASDAQ: GRMN), today announced the availability of Electronic Stability and Protection (ESP-X) technology for aircraft using Garmin’s G3X autopilot servos. This electronic monitoring and stability augmentation system works to assist the pilot in maintaining the aircraft in a stable flight condition. Available for the first time in this market, ESP-X functions independently of Garmin’s G3X autopilot system and works in the background to provide an extra envelope of protection to help avoid inadvertent flight attitudes and provide airspeed protection while the pilot is hand-flying the aircraft.
“Until today, the safety benefits offered by electronic stability protection have not been available to the experimental and light sport market and we are thrilled to now provide this technology to our loyal G3X and G3X Touch customers,” said Carl Wolf, vice president of aviation sales and marketing. “Garmin ESP-X brings a new level of capability and layer of protection to customers flying with our autopilot and we are excited to be the first to bring this technology to this market, which at one time was only available on certified aircraft.”
Should the pilot become inattentive, Garmin ESP-X provides pilots with an added measure of protection and correction to enhance in-flight safety. When a pilot exceeds user-selected pitch, roll or airspeed limitations, Garmin ESP-X provides gentle nudges on the flight controls to lessen the aircraft’s pitch attitude or bank angle. Even further, the correcting force becomes stronger if the aircraft pitch, bank or airspeed exceedance grows further away from the preset limits. While ESP-X adds a substantial margin of safety to the wide range of flight regimes within its designed operational limits, there are in-flight situations that can exceed the recovery capabilities of ESP-X technology.
As the pilot takes corrective action to reduce the abnormal flight attitude or airspeed, the influence of Garmin ESP-X eventually fades and turns off when the aircraft returns to its normal flight envelope. Conversely, should the pilot become incapacitated and the system detects it has been activated for more than fifteen seconds, the autopilot engages with the flight director in Level Mode, bringing the aircraft to level flight until the pilot commands otherwise. In addition to flight control corrections, pilots are also provided visual cues on the displays of G3X and G3X Touch indicating ESP-X is engaged. Yellow chevrons provide visual pitch guidance and configurable roll limit indicators indicate where ESP-X engages to provide bank guidance.
Garmin ESP-X goes beyond providing pitch and bank envelope protection to also offer high and low airspeed protection. In a high airspeed situation, Garmin ESP-X engages the Garmin G3X autopilot servos to apply back pressure to increase the aircraft’s pitch attitude. Built-in parameters further prevent the aircraft from exceeding G-limit load factors as the pitch attitude increases. In low airspeed situations, Garmin ESP-X engages to provide a gentle pitch-down force to reduce the possibility of stalling the aircraft. Furthermore, when the aircraft is operating within 200 feet of the ground, Garmin ESP-X automatically disables.
Utilizing Garmin’s G3X autopilot servos, Garmin ESP-X continuously monitors attitude and airspeed while the pilot hand flies the aircraft to provide pre-determined correcting inputs should they be needed. Pitch, roll and airspeed envelope protection parameters are customizable on the displays of G3X and G3X Touch, so pilots can select what limitations best suit their individual flying habits. For flight training or aerobatics, Garmin ESP-X can easily be inhibited within the automatic flight control system (AFCS) menu of G3X and G3X Touch or by installing an optional dedicated switch in the panel.
Garmin ESP-X is available as a software update at no cost for customers with G3X and G3X Touch flight display systems with Garmin’s integrated autopilot. For additional information or to download this software upgrade, visit: www.garmin.com/experimental.
