What are the potential dangers of using a helicopter for aerial surveying?
Using a helicopter for aerial surveying offers many advantages, such as access to remote or rugged terrain, flexibility in flight paths, and the ability to cover large areas relatively quickly. However, there are also potential dangers associated with helicopter surveying:
Weather Conditions: Helicopter surveying is highly dependent on weather conditions. Adverse weather, such as high winds, fog, or storms, can make flying unsafe and may lead to accidents or delays.
Terrain Hazards: Surveying in mountainous or rugged terrain poses risks such as sudden changes in elevation, narrow valleys, or obstacles like power lines and trees, which increase the chances of collisions or accidents.
Mechanical Failures: Like any aircraft, helicopters can experience mechanical failures, such as engine malfunctions or hydraulic system problems, which can result in loss of control or forced landings.
Pilot Error: Human error, including mistakes in navigation, judgment, or response to emergencies, can lead to accidents during survey flights.
Fuel Management: Helicopters have limited fuel capacity, and mismanagement of fuel levels or unexpected fuel consumption due to weather conditions or flight deviations can result in emergencies if fuel runs low during flight.
Wildlife Encounters: Helicopters flying at low altitudes may encounter wildlife, which can pose risks of bird strikes or other unpredictable interactions.
Electromagnetic Interference: Aerial survey equipment, such as LiDAR or magnetometers, may be sensitive to electromagnetic interference, which can affect data quality or accuracy if not properly accounted for.
Fatigue: Long survey flights can lead to pilot and crew fatigue, which may impair decision-making and increase the risk of accidents
