Airlines face challenges from GPS jamming and restricted airspaces

Airlines face challenges from GPS jamming and restricted airspaces

Global air transport relies on the collaboration of various stakeholders, including airport operators, governments, and military entities. Each country is responsible for managing its own airspace, which includes areas above both land and sea. Pilots use GPS to navigate efficiently through different airspaces, allowing for direct routes and reduced flight times.

However, airspace closures and GPS jamming have increasingly impacted airline operations. Military authorities or national governments may close airspace to ensure safety, causing airlines to delay or cancel flights. If not flying directly to a destination within closed airspace, airlines must reroute flights, leading to longer travel times and increased fuel consumption.

Airspace can be closed for reasons such as military exercises, natural disasters, conflicts, or high-profile events. These closures affect the flow of goods and humanitarian efforts provided by nonprofit organizations through their airline partners.

For instance, restrictions over Russian airspace have significantly impacted Western carriers. Following Russia's invasion of Ukraine in 2022, Russia closed its airspace to most European and North American operators in response to sanctions. This forced some flights from Europe to Asia to reroute via Central Asia.

"Naturally, this extends the flight by 30-40 minutes one way and entails additional costs for the company," said Uzbekistan Airways CEO Shukhrat Khudaikulov regarding altered routes due to Russian restrictions.

Conflicts in regions like the Middle East have also led to multiple airspace restrictions. Increased tensions have affected busy corridors in the area, with countries like Jordan closing their airspace following missile launches by Iran.

In Africa, military coups and civil unrest led to several airspace closures in 2023. The closure of Niger's airspace added challenges for airlines operating between Europe and sub-Saharan Africa.

Apart from enforced closures, some regions are voluntarily avoided by airlines due to risks such as high terrain or turbulence. For example, airlines avoid flying over Tibet despite open airspace due to its mountainous landscape.

GPS interference poses another challenge for pilots who rely heavily on it for navigation. Intentional jamming has increased worldwide due to geopolitical tensions. Several incidents have been reported near Eastern Europe bordering Russia where airlines experienced GPS signal disruptions.

GPS spoofing involves transmitting signals that mislead aircraft about their position or time. It is a serious risk as it can cause aircraft deviations from intended routes. OPSGROUP reported a significant increase in spoofing incidents last year affecting daily flights.

Despite these challenges, many aircraft are equipped with redundant systems and pilots are trained to manage risks associated with GPS jamming and spoofing effectively.
