Mo i Rana, Norway – A blanket of fog has caused widespread disruptions to air travel at Røssvoll Airport, leading to numerous flight cancellations and diversions over the last two days. The ongoing issues have affected passengers traveling to and from this key regional airport.
Initial Disruptions and Cancellations
The problems began on monday and continued into tuesday, with the evening flight from Trondheim unable to land. Several morning flights,including the 06:25 service to Trondheim,were also canceled,leaving passengers stranded. The fog persisted,leading to the cancellation of the 09:25 flight to Bodø.
Tuesday’s Flight Status: A Rollercoaster
Throughout Tuesday, the situation remained fluid.A flight from Trondheim did manage to land at 14:31, just four minutes behind schedule, briefly offering a reprieve.This allowed the subsequent departure to Bodø at 14:55 to proceed as planned.However, the positive trend was short-lived.
Further Cancellations and Diversions
Flights arriving from Bodø at 11:30 and 20:00, as well as departures to Bodø at 18:30 and Trondheim at 20:15, were all canceled. One flight originally bound for Mo i Rana from Trondheim was diverted to Mosjøen, where passengers were transported onwards by bus.
Widerøe, the airline primarily affected, apologized for the delays and is working to find alternative travel arrangements for impacted passengers. According to Widerøe press officer, Satha Sritharan, the challenges stem directly from the persistent fog conditions hindering safe landings.
Scheduled Departures and Arrivals – October 15th
Here’s a look at the originally scheduled flights for today:
| Departures | Arrivals |
|---|---|
| 11:50: Trondheim | 11:30: Bodø |
| 14:55: Bodø | 14:35: Trondheim |
| 15:40: Trondheim | 15:25: Bodø |
| 18:30: Bodø | 18:15: Trondheim |
| 20:15: Trondheim | 20:00: Bodø |
| 23:00: Trondheim |
Did You Know? Fog is formed when water vapor condenses into tiny water droplets suspended in the air, reducing visibility. This is especially common in coastal regions like Mo i Rana.
Pro Tip: When traveling during periods of potential fog,always check your flight status with the airline before heading to the airport and allow for extra travel time.
Understanding the Impact of Weather on Air Travel
Weather conditions are a primary factor in flight disruptions globally. Fog, snow, ice, and strong winds can all lead to delays and cancellations, as safety is the paramount concern for airlines. airports rely on sophisticated meteorological equipment and procedures to assess risk associated with inclement weather. According to the Federal Aviation Management (FAA), weather-related delays cost the U.S. aviation industry over $10 billion annually. FAA Weather Information

What are the primary differences between Radiation Fog, Advection Fog, Upslope Fog, and Steam Fog in terms of their formation?
Understanding the Impact of Fog on Flight
Fog, a visible aerosol consisting of tiny water droplets suspended in the air, presents a significant challenge to air traffic operations. Its impact extends beyond reduced visibility, affecting aircraft performance and increasing the complexity of air traffic control. understanding these effects is crucial for maintaining safety and efficiency in aviation. Key terms related to this include low visibility operations (LVO), reduced visibility takeoff (RVT), and instrument meteorological conditions (IMC).
How Fog Forms & Types Relevant to Aviation
Different types of fog pose varying degrees of risk. Recognizing these is the first step in mitigating their impact:
* radiation Fog: Forms on clear, calm nights when the ground cools, condensing water vapor. Common in valleys and low-lying areas.
* Advection Fog: Occurs when warm, moist air moves over a cooler surface. Frequently seen near coastlines.
* Upslope Fog: Develops as air is forced to rise up a slope, cooling and condensing.
* Steam Fog: Forms when cold air moves over warm water.
Aviation meteorologists closely monitor fog forecasting to predict its formation and dissipation, providing critical data to pilots and air traffic controllers.
Operational Procedures During Foggy Conditions
When fog descends, a cascade of procedures is initiated to ensure safe air travel. These procedures are governed by regulations from organizations like the FAA (Federal Aviation Governance) and EASA (European Union Aviation Safety Agency).
Air Traffic Control (ATC) Adjustments
ATC plays a pivotal role in managing traffic during reduced visibility. Key adjustments include:
- Increased Separation: ATC increases the distance between aircraft, both horizontally and vertically, to provide a larger safety margin. This is often achieved through increased spacing standards.
- Flow Control: ATC may implement flow control measures, such as ground delays or rerouting flights, to manage the capacity of airports and airspace.
- Priority Handling: Emergency and critical flights may receive priority handling to ensure timely arrival or departure.
- enhanced Surveillance: Utilizing radar systems, including precision approach radar (PAR), and advanced surveillance technologies to maintain situational awareness.
Pilot Procedures & Technology
Pilots rely on a combination of training, technology, and adherence to strict procedures:
* Instrument flight Rules (IFR): Flights operate under IFR, relying on instruments for navigation and control.
* Low Visibility Procedures (LVP): Airports implement specific LVP, outlining procedures for taxiing, takeoff, and landing in low visibility.
* Enhanced Vision Systems (EVS): EVS use infrared or millimeter wave technology to provide pilots with a clearer view of the runway and surrounding habitat.
* Head-Up Displays (HUD): HUD project critical flight information onto the pilot’s forward field of view, reducing the need to look down at instruments.
* Ground Roll Monitoring: Systems that monitor the aircraft’s speed and position during takeoff and landing, providing alerts if parameters deviate from safe limits.
technological Advancements in Fog Mitigation
Ongoing research and development are yielding innovative technologies to combat the challenges posed by fog.
Surface Movement Guidance Control system (SMGCS)
SMGCS utilizes a combination of radar, sensors, and lighting systems to guide aircraft and vehicles on the ground during low visibility. This system is crucial for safe taxiing and runway navigation.
Low Visibility Taxiing Systems (LVTS)
LVTS employ advanced sensors and displays to provide pilots with real-time information about their position and surroundings during taxiing in fog.
Satellite-based Augmentation systems (SBAS)
SBAS, like WAAS (Wide Area Augmentation System) in the US and EGNOS (European Geostationary Navigation Overlay Service) in Europe, enhance the accuracy and reliability of GPS signals, improving navigation performance in all weather conditions.
Real-World Examples & Case Studies
The impact of fog on air traffic is well-documented.
* London Heathrow Airport (2010): Severe fog caused widespread flight cancellations and delays, disrupting travel for hundreds of thousands of passengers. This event highlighted the vulnerability of major airports to fog and spurred investment in improved LVP and technology.
* San Francisco International airport (SFO): Frequently experiences fog, especially during the summer months. SFO has implemented advanced SMGCS and LVP to mitigate the impact of fog on operations.
* Denver International Airport (DIA): Situated at a high altitude, DIA is prone to fog formation. The airport utilizes sophisticated weather forecasting and monitoring systems to anticipate and manage fog events.
Benefits of Proactive Fog Management
Effective fog management yields significant benefits:
* enhanced Safety: Reduced risk of accidents and
