Landing Zone Operations · Patient Loading and Unloading · In-Flight Safety Considerations
Landing zone (LZ) operations present significant hazards requiring careful coordination between ground personnel and flight crews. The flight paramedic often serves as the communication link between the pilot and ground responders.
LZ site selection requires a flat area of at least 100 feet by 100 feet for day operations and larger for night operations. The area should be free of debris, wires, poles, trees, and other obstacles. Ground personnel should assess for slope, surface stability, and potential hazards including loose materials that could become airborne.
LZ marking for night operations includes positioning emergency vehicles with headlights illuminating the landing area from different angles, avoiding direct light toward the approaching aircraft. A single light source or vehicle at the upwind position indicates wind direction. Flares should not be used due to fire risk.
Ground personnel must remain outside the rotor arc during approach and departure. Once the aircraft lands, approach should occur only after pilot signal, from the front quadrant, in a crouched position, and with all loose items secured. Side and rear approaches are prohibited due to tail rotor hazards.
Wire strike represents a leading cause of helicopter accidents. Wires are often difficult to see, especially in reduced visibility. Ground personnel should specifically report wire locations, and pilots may request wire marking with visible materials.
Patient loading procedures vary by aircraft type but share common safety principles. The pilot maintains aircraft control and situational awareness throughout loading. Medical crew members manage patient movement and equipment transfer.
Rotor-wing loading typically occurs with rotors turning (hot loading) to minimize ground time. Approaches and departures follow established paths, usually from the front or sides. Patients on stretchers must be secured below rotor height. IV poles, monitor cables, and other equipment must be controlled to prevent contact with rotors or ingestion into engines.
Patient securing requires proper restraint systems, typically multi-point harnesses or equivalent systems. IV lines, monitoring cables, ventilator circuits, and other attachments must be managed to prevent disconnection during movement or turbulence. Medication infusions should be secured and visible for ongoing monitoring.
Equipment placement follows standardized configurations allowing rapid access to critical items. Crash-worthy equipment mounting prevents objects from becoming projectiles during hard landings or accidents.
In-flight emergencies require immediate recognition and appropriate response. Flight paramedics must understand emergency procedures for their specific aircraft, including emergency exits, fire suppression, and crash position.
Post-crash survival training addresses egress procedures, fire avoidance, and survival techniques. Water operations require additional training in underwater egress and use of emergency flotation devices.
Personal protective equipment includes flight suits or flame-resistant clothing, helmets, hearing protection, eye protection, and gloves. Night vision goggle (NVG) operations require specific training and awareness of NVG limitations.
Communication systems include intercommunication systems (ICS) for crew communication and radios for external communication. Medical crews must understand communication protocols, including when to interrupt pilot workload and appropriate radio procedures.
