This article is based on an official press release from Garmin.
Garmin GHA 15 Height Advisor Receives FAA Approval for Certified Aircraft
Garmin has announced that its GHA 15 Height Advisor, a radar-based altitude monitoring device, has received Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) approval. Previously available only for the experimental market, this certification allows the installation of the device in over 500 models of Class I and Class II certified aircraft.
The approval marks a significant shift in the accessibility of radar altimetry for general aviation pilots. According to the company, the GHA 15 is available immediately at a price of $2,695. This pricing strategy positions the device as a cost-effective alternative to traditional radar altimeters, which have historically been priced significantly higher and reserved for business jets or commercial airliners.
Bringing Radar Altimetry to General Aviation
The GHA 15 is designed to provide pilots with precise Height Above Ground Level (AGL) readings during the critical final phases of flight. While standard barometric altimeters rely on air pressure and can be subject to calibration errors or terrain variations, the GHA 15 uses radio frequency technology to measure the actual distance between the aircraft and the ground.
Garmin states that the device is capable of providing AGL data from 500 feet down to the surface. The system integrates with the Garmin GI 275 electronic flight instrument to display altitude data and generate audible callouts directly to the pilot’s headset. These callouts, such as “50 feet,” “20 feet,” and “10 feet”, are user-configurable and intended to assist pilots in judging flare height and landing timing.
“The GHA 15 provides a cost-effective solution that helps reduce pilot workload and provides confidence during the approach and landing phases of flight.”

Technical Specifications and Accuracy
The unit is a compact, all-in-one module that mounts to the underside of the aircraft fuselage. Weighing less than one pound (approximately 0.45 kg), the device is roughly the size of a deck of cards, minimizing the structural impact of installation. According to the technical details released by Garmin, the GHA 15 offers the following accuracy levels:
- 3 to 100 feet AGL: +/- 1.5 feet
- 100 to 500 feet AGL: +/- 2%
Installation and Compatibility
The FAA STC covers a broad range of single-engine and twin-engine piston aircraft (Class I and Class II). This includes popular general aviation airframes such as the Cessna 172, Piper PA-28, Beechcraft Bonanza, and Mooney M20 series. To function, the GHA 15 must be interfaced with a Garmin GI 275 electronic flight instrument. For experimental aircraft, the device remains compatible with the G3X Touch flight display.
AirPro News Analysis: The Democratization of Safety Tech
The certification of the GHA 15 represents a notable development in the “democratization” of avionics safety features. Historically, radar altimeters (such as the Garmin GRA 55) have cost upwards of $7,000, placing them out of reach for the average private pilot. By offering a certified “Height Advisor” for under $3,000, Garmin is effectively bridging the gap between recreational flying and professional-grade situational awareness.
We believe this technology will be particularly valuable in three specific scenarios:
- Night Landings: The “black hole” effect can make visual depth perception difficult at night. Audio callouts provide an objective reference for the ground.
- Backcountry Operations: In uneven terrain, barometric altimeters may not accurately reflect the distance to the ground. Radar-based data offers a safety net for off-airport landings.
- Water Landings: For amphibious aircraft, judging height over “glassy water” is notoriously hazardous. Precise AGL readings can prevent spatial disorientation during touchdown.
It is important to note the distinction Garmin makes by labeling this product a “Height Advisor” rather than a TSO-certified radar altimeter. While it provides similar functionality, it is intended for advisory purposes and does not replace the higher-end equipment required for complex instrument approaches like CAT II or CAT III landings.

FAA Investigates Southwest Airlines Ground Collision at PVD
Two Southwest Boeing 737s collided during pushback at Rhode Island T.F. Green Airport on June 11, 2026. FAA investigation opened.

This is a developing story. Information may change as official details are released.
This article summarizes reporting by WPRI, NBC 10, Daily Voice, and CBS News Baltimore.
The Federal Aviation Administration (FAA) has opened an investigation after two Southwest Airlines Boeing 737 aircraft collided during pushback at Rhode Island T.F. Green International Airport (PVD) late on June 11, 2026.
The ground collision resulted in no reported injuries but forced the cancellation of both flights and the grounding of the involved aircraft for mandatory safety inspections. According to reporting by the Daily Voice and NBC 10, the incident highlights ongoing operational challenges on airport ramps, occurring just weeks after a similar event involving the same carrier at another East Coast facility.
Details of the ground collision
At approximately 10:45 p.m. local time, Southwest Airlines Flight 3515, bound for Ronald Reagan Washington National Airport (DCA), was pushing back from its gate. During the maneuver, the aircraft’s wing made contact with the tail of Southwest Airlines Flight 3409, which was scheduled to depart for Chicago Midway International Airport (MDW).
Both aircraft returned to their respective gates following the contact, allowing passengers to deplane normally. Southwest Airlines confirmed that no injuries occurred among passengers or crew members. The carrier subsequently canceled both flights and reaccommodated the affected travelers.
“Southwest Airlines is aware of an incident involving two of our aircraft at Rhode Island T. F. Green International Airport. We are investigating further and will be thoroughly inspecting the two aircraft,”
the airline stated in remarks provided to local media, adding that safety remains its highest priority.
Local media outlets, including NBC 10, reported passenger accounts suggesting that Flight 3515 continued to move briefly after the initial impact. These accounts claim passengers verbally alerted the flight crew to the collision. Neither Southwest Airlines nor the FAA has officially verified these specific passenger narratives, and the official sequence of events remains under investigation.
Regulatory response and recent precedent
The FAA confirmed on June 12, 2026, that it is investigating the circumstances surrounding the collision. Ground operations during pushback rely heavily on coordination between flight crews and ground personnel, particularly in ramp areas where air traffic controllers do not maintain direct communication with the aircraft.
This event follows a comparable occurrence on May 4, 2026, at Baltimore/Washington International Thurgood Marshall Airport (BWI). In that instance, two Southwest Airlines Boeing 737s clipped wings during pushback operations. The FAA investigated the BWI incident, noting the specific communication dynamics between ground crews and the flight deck in non-controlled ramp sectors.
AirPro News analysis
We note that while ground collisions during pushback rarely pose a severe threat to passenger safety, they represent a significant operational and financial burden for carriers. Ramp incidents require immediate grounding of the involved airframes, triggering mandatory structural inspections and potential repairs. The recurrence of pushback-related contact within a single airline’s network over a short period may prompt internal reviews of ground handling procedures, wingwalker positioning, and ramp communication protocols. Until the FAA concludes its investigation, the specific cause of the PVD collision remains undetermined.

Turkish Airlines 777-300ER Wing Strike at Antalya Airport
A Turkish Airlines Boeing 777-300ER struck a radar antenna pole taxiing at Antalya Airport, prompting evacuation and a formal investigation.

This is a developing story. Information may change as official details are released.
This article summarizes reporting by Hürriyet.
A Turkish Airlines (TK) Boeing 777-300ER sustained damage and prompted a passenger evacuation after its right wing struck a ground radar antenna pole while taxiing at Antalya Airport (AYT) on June 11, 2026.
The incident, which occurred at approximately 20:00 local time following Flight TK2430 from Istanbul, resulted in minor injuries among the passengers. According to official statements reported by Hürriyet, the widebody aircraft was maneuvering toward its parking position on Apron-1 when the collision occurred, leading to an immediate evacuation on the tarmac.
Conflicting passenger and injury reports
Following the evacuation, official sources provided conflicting figures regarding the number of passengers on board and the extent of injuries. In a public statement, Turkish Airlines Senior Vice President of Communications Yahya Üstün confirmed the evacuation, stating that 267 passengers were safely removed from the aircraft. The airline reported that one passenger sustained minor injuries and was in good health.
Conversely, the Turkey Ministry of Transport released a separate statement indicating a higher passenger count. The ministry reported that the aircraft was carrying 284 adult passengers and four infants. Furthermore, the government authority stated that three passengers suffered minor injuries during the event. Both entities confirmed that the aircraft, registered as TC-LKD, was towed to a parking area after the necessary safety checks and passenger removal were completed.
Investigation into the ground collision
A technical investigation into the ground collision has been initiated by the Turkey Ministry of Transport and the General Directorate of State Airports Authority (DHMI). The official cause of the incident remains under investigation.
While the airline noted the aircraft was approaching its parking position, preliminary remarks from the Ministry of Transport suggested the Boeing 777-300ER made contact with the radar pole after entering an incorrect taxiway line. Final determinations regarding the aircraft routing, ground control instructions, and the sequence of events will be established by the investigating authorities.
AirPro News analysis
Ground collisions involving widebody aircraft like the Boeing 777-300ER often highlight the tight tolerances required when maneuvering large airframes around airport infrastructure. While we await the official investigation findings, safety reviews following such events typically examine airport taxiway markings, lighting, and the clarity of ground control communications. The discrepancy in passenger manifests between the operator and the regulator is a notable detail, though initial reporting conflicts frequently occur in the immediate aftermath of an evacuation before final reconciliations are completed.

NTSB Final Report: Southwest Flight 4273 Turbulence Encounter
NTSB cites ATC communication delays and sector overload in Southwest Airlines turbulence event over Gulf of Mexico.

This is original reporting and analysis by AirPro News.
The National Transportation Safety Board (NTSB) has released its final report on a severe turbulence encounter involving a Southwest Airlines Boeing 737-700, detailing how rapidly developing convective weather and air traffic control communication delays factored into an event that seriously injured two people.
The April 3, 2024, incident aboard Southwest Airlines Flight 4273 over the Gulf of Mexico highlights the operational risks when severe weather systems intersect with technical limitations at air traffic control facilities. According to the NTSB investigation, the aircraft was navigating complex weather en route from New Orleans to Orlando when the encounter occurred, resulting in serious injuries to one flight attendant and one passenger, alongside minor injuries to a second flight attendant.
Weather conditions and the turbulence encounter
Flight 4273, operated by a Boeing 737-700 (registration N567WN) with 140 passengers and five crew members on board, was traveling from Louis Armstrong New Orleans International Airport (MSY) to Orlando International Airport (MCO).
At 11:55 UTC, a Convective Significant Meteorological Information (SIGMET) advisory was issued for the region, warning of cloud tops exceeding 45,000 feet.
At approximately 08:20 Eastern Daylight Time, the aircraft encountered severe turbulence over the Gulf of Mexico. The NTSB confirmed the aircraft itself sustained no damage during the event and the flight crew was able to continue the flight.
Air traffic control workload and technical limitations
The NTSB report outlines compounding factors at the Jacksonville Air Route Traffic Control Center (JAX ARTCC) that affected the flight routing through the weather system.
During the incident, the specific JAX ARTCC sector was managing a traffic volume that exceeded its target capacity of 20 aircraft.
This high workload was exacerbated by a technical limitation involving the facility communication infrastructure. The primary VHF antenna at JAX ARTCC had been rendered inoperative following a fire in October 2023. As a result, controllers were utilizing a temporary satellite relay connection to communicate with aircraft in the sector.
The NTSB determined this satellite relay introduced a 600-millisecond round-trip transmission delay, complicating timely communication between controllers and flight crews navigating the dynamic weather environment.
AirPro News analysis
We note that the findings in this final report underscore a critical vulnerability in the National Airspace System. When primary communication infrastructure fails, the fallback systems must be robust enough to handle high-stress, time-critical scenarios like severe convective weather deviation. A 600-millisecond delay might seem negligible in routine operations, but in a saturated sector where controllers are issuing rapid heading changes to keep aircraft clear of building storm cells, that latency degrades situational awareness and increases the risk of weather encounters. The NTSB documentation of this technical shortfall will likely prompt further scrutiny of contingency communication systems at major en route centers.
