Nestled in the heart of the French Alps, the Gendarmerie Air Section (Section Aérienne de Gendarmerie, or SAG) of Chamonix serves as a lifeline for those drawn to the treacherous beauty of the Mont Blanc massif. Working in close coordination with the Peloton de Gendarmerie de Haute Montagne (PGHM), a specialized high-mountain rescue unit, these airborne crews ensure that mountaineers, skiers, and hikers receive swift, expert assistance when danger strikes.
Capt. Yannick Herman, who has been squadron leader since 2019 and a pilot with the FAGN (Forces Aériennes de la Gendarmerie Nationale) since 2005, is qualified on both the Eurocopter AS350 Écureuil and the EC145, logging more than 4,700 flight hours.
As commander of the Chamonix section, he is responsible for flight safety, technical resource management, operational readiness, and crew welfare. SAG Chamonix maintains a 24/7 alert system, staffed by a pilot, an on-board mechanic, and additional radio alert personnel. The unit consists of three pilots, four winch-equipped mechanics, one aerial surveillance operator, and supporting office staff.
The demands of the role, both technical and personal, mean that only volunteers can serve here. Candidates are also expected to have completed tours at one or two other mountain bases before becoming eligible, ensuring they arrive with the experience needed for such a challenging post.
A legacy of aerial rescue
The need for specialized mountain rescue services in France became clear in the mid-20th century, as alpine tourism and mountaineering surged in popularity. The perilous conditions of the high mountains demanded a dedicated force trained to handle emergencies in such extreme environments.
The Gendarmerie’s history of aerial rescue began on May 6, 1954, with the establishment of its first airborne unit — ushering in a new era of mountain operations. Just three years later, the arrival of the Aérospatiale Alouette II helicopter transformed high-altitude rescues, enabling crews to reach climbers stranded on sheer rock faces or trapped deep within icy crevasses.
To meet the growing demand, the PGHM was created in 1958 to specialize in mountain rescue, soon followed by the formation of the Gendarmerie Air Section in Chamonix. Together, these ground and air units revolutionized mountain rescue, cutting response times and dramatically improving the efficiency of missions.
As technology advanced, so did the fleet. The introduction of the AS350B Écureuil in 1978 delivered greater agility and power, while the EC145, added in 2002, became the backbone of high-altitude operations. Outfitted with winches, stretchers, and advanced navigation and medical equipment, these helicopters allow SAG to carry out rescues in some of the most demanding conditions on Earth.
A highly trained, elite team
Operating in the extreme environment of the Mont Blanc region demands skill, precision, and courage. The SAG of Chamonix is composed of eight elite military personnel, including seasoned pilots and expert winch operators. Each member undergoes rigorous training, often building on years of experience in both military aviation and mountain flying.
The unit’s mechanics play dual roles: they not only keep the aircraft in peak condition but also serve as in-flight winch operators, lowering rescuers into perilous situations where every second counts. Their expertise is critical during evacuations — whether extracting climbers from near-vertical rock faces or pulling skiers buried in avalanches.
When discussing pilot and mountain training within the FAGN, Capt. Herman explained that the path begins with an 18-month basic course at the Army’s flight school in Dax, where candidates earn their pilot’s license. This is followed by five to six weeks at
CNIFAG (Centre National d’Instruction de Ski et d’Alpinisme de la Gendarmerie), where pilots receive qualifications specific to the Gendarmerie, such as winching, camera operations, and aircraft type ratings. The rigorous program ensures that personnel are fully prepared for the challenges of high-altitude missions, learning from a multidisciplinary team of mountain guides, pilots, flight engineers, and rescue specialists whose combined expertise enables seamless coordination in even the most complex rescues.
After assignment to a unit, young pilots log about 50 hours of operational flight under dual control before being cleared for independent missions. Those seeking to qualify as mountain pilots undergo an additional detection phase, followed by a specialized mountain flight course. Conducted in Briançon — also in the French Alps but farther south — the program spans four two-week sessions across the seasons, ensuring pilots are ready to operate safely in every mountain environment.
Alpine rescue in action
The primary mission of SAG Chamonix is aerial rescue across the Mont Blanc massif and surrounding regions. These operations often involve evacuating injured climbers, skiers, or hikers from remote, inaccessible terrain. Activity peaks during the tourist season, but missions continue year-round.
In addition to rescues, SAG also supports law enforcement by monitoring protected areas, detecting illegal activities, and assisting with major regional events. The unit frequently collaborates with Sécurité Civile and medical teams to provide a coordinated emergency response.
“Mountain rescue missions are conducted under the authority of the PGHM, which determines the necessary resources for each operation,” said Capt. Herman, explaining how these operations unfold. “If a helicopter is deemed the most effective option, the PGHM coordinates with SAG for assistance.”
During the day, the helicopter can be airborne within minutes, while at night the typical delay is about 40 minutes. The Air Section is able to respond across the entire territory, at all altitudes, day or night. The only constraints come from adverse weather conditions, such as strong winds, cloud cover, fog, or heavy snowfall.
Successful missions require a pilot and a winch mechanic at minimum, supported by specialized equipment, such as cameras, night vision goggles (NVGs), thermal binoculars, searchlights, and winches. Depending on the situation, the crew may carry rescuers, doctors, investigators, or intervention teams. Night operations are only authorized for verified life-threatening emergencies and require stricter weather minimums than daytime flights.
A typical rescue team consists of five members: a pilot, a winch operator, two PGHM rescuers, and a doctor. This composition is flexible — for example, avalanche responses may require additional rescuers during the initial search phase, with the doctor joining later.
Each team member serves a specific role: the SAG crew transports rescuers to and from the scene, while PGHM personnel — trained as first aiders, judicial police officers, and high mountain guides — lead the rescue on the ground. The emergency physician doctor is qualified to work independently in harsh alpine conditions and is responsible for medical decision-making.
The crews are also trained and equipped for survival in case they become stranded in the mountains. Survival kits, specialized clothing, and mountain survival training ensure they can withstand the cold and move safely in the environment.
The helicopters themselves are tailored for alpine missions. Equipped with skis, winches, and aluminum floors designed for crampon use, they also carry rescue and survival equipment. High-altitude performance demands light takeoff weight, so only essential fuel, personnel, and gear are carried on each mission.
Swift response in the face of tragedy
For the SAG, each mission carries the weight of life and death. On April 9, 2023, the unit played a crucial role in the response to a massive avalanche on the Armancette Glacier, which tragically claimed several lives. The swift coordination between aerial and ground teams underscored the indispensable role of SAG in large-scale mountain emergencies. Their rapid intervention enabled rescuers to reach survivors trapped beneath heavy of snow, demonstrating how vital aerial support is in such extreme conditions.
Beyond high-profile rescues, the unit is equally essential for medical evacuations, law enforcement support, and high-risk interventions, ensuring that no corner of the Mont Blanc massif is ever beyond their reach.
With more than 60 years of mountain rescue experience, the Gendarmerie Air Section of Chamonix has become a symbol of dedication, skill, and courage. Their presence provides reassurance across the Mont Blanc region, giving adventurers the confidence to explore its majestic yet unforgiving landscapes. Whether soaring through stormy skies or hovering just above a frozen peak, these airborne crews embody the very spirit of mountain rescue — proving that when disaster strikes, help is never far away.
Each year, SAG Chamonix carries out hundreds of missions, from assisting injured hikers to evacuating stranded climbers. In August 2022 alone, the unit responded to multiple emergencies, including paragliders in distress and elderly hikers requiring evacuation — clear evidence of their versatility and constant readiness. Yet as mountain tourism grows, the demand for their services continues to rise. Meeting this challenge requires ongoing training, resource management, and constant investment in new technologies to keep the unit at the forefront of alpine rescue.
Looking ahead, SAG Chamonix continues to stand as a testament to France’s commitment to mountain safety and rescue excellence. Capt. Herman emphasized the need to prepare for the arrival of the Airbus H145 D3 in 2026 — a significant upgrade that will enhance the unit’s capabilities in the harsh alpine environment.
Yet, he noted, technology alone will not define the future. Climate change is already reshaping the mountains with melting glaciers, rising temperatures, and landslides, introducing new and unpredictable dangers. Meeting these challenges will require both innovation from manufacturers and constant adaptation by the FAGN. Through this balance of tradition and progress, SAG Chamonix is poised to remain a lifeline in the Alps — as resilient and effective in the decades ahead as it has been for the past 60 years.
