Key Takeaways
- Air New Zealand has cancelled 38 flights in November due to volcanic ash from Whakaari White Island, affecting Bay of Plenty flight schedules.
- A prominent GP, Dr. Luke Bradford, is calling for better communication from the airline regarding cancellations and earlier warnings.
- Volcanic ash can travel long distances and affect flight safety, making cancellations necessary.
- Air New Zealand aims to give customers as much notice as possible, but conditions can change quickly due to unpredictable wind patterns.
- The airline prioritizes safety and takes a conservative approach when making decisions about flight cancellations.
Introduction to the Issue
A prominent GP, Dr. Luke Bradford, is calling on Air New Zealand to improve its communication regarding flight cancellations, particularly when they are caused by volcanic ash from Whakaari White Island. The airline cancelled 38 flights in November due to the ash, which has been affecting Bay of Plenty flight schedules. Dr. Bradford’s own flight from Tauranga to Christchurch was cancelled, and he received a message about the cancellation only nine hours before the scheduled departure time, with the reason given as "operational requirements." He believes that the airline should provide more transparency and explanations for cancellations, as well as earlier warnings to allow passengers to make alternative travel arrangements.
The Impact of Volcanic Ash on Flights
The volcanic ash from Whakaari White Island has been causing disruptions to flights in the Bay of Plenty region. The ash can travel long distances and affect flight safety, making cancellations necessary. Tauranga Airport manager Ray Dumble explained that volcanic ash can be blown by wind to areas such as Tauranga or Rotorua, and that safety is the top priority when it comes to flight operations. Air New Zealand chief safety and risk officer Nathan McGraw stated that the movement of volcanic ash is not always predictable, and conditions can change quickly, making it challenging to provide early warnings.
Air New Zealand’s Response
Air New Zealand has stated that it aims to give customers as much notice as possible when flights are disrupted, but the unpredictability of volcanic ash movement can make it difficult to provide early warnings. The airline’s proactive cancellation decision on Monday night was based on predicted wind patterns for Tuesday, and McGraw emphasized that safety is always the top priority when making decisions about flight cancellations. While the airline understands the frustration caused by cancellations, it takes a conservative approach when it comes to volcanic activity and gets intelligence from various sources, including the Volcanic Ash Advisory Centre and GeoNet’s Volcano Monitoring Group.
The Volcanic Activity on Whakaari White Island
Whakaari White Island has been at Alert Level 3, indicating minor eruptive activity, since the end of October. GeoNet issues a Volcano Activity Notice for Aviation to the aviation industry when there is volcanic unrest and ash cloud activity. According to Earth Sciences NZ volcanologist Geoff Kilgour, the island has been generating "weakly loaded volcanic ash plumes" throughout November, punctuated by more visible energetic plumes that last several minutes and rise up to 3km. Gas and fine particles from the plume may be blown towards the Bay of Plenty coastline in some wind conditions, but ashfall on the mainland is unlikely without a significant uptick in activity.
Conclusion and Recommendations
In conclusion, the volcanic ash from Whakaari White Island has been causing disruptions to flights in the Bay of Plenty region, and Air New Zealand has been cancelling flights to ensure safety. While the airline aims to provide early warnings, the unpredictability of volcanic ash movement can make it challenging. Dr. Bradford’s call for better communication and earlier warnings is reasonable, and the airline should consider providing more transparency and explanations for cancellations. By prioritizing safety and taking a conservative approach, Air New Zealand can minimize the impact of volcanic ash on flights and provide better service to its customers.
