India’s 17-Day Airspace Notice Puts Pakistan on Alert as IAF Prepares for Major Drills

India’s latest airspace reservation has drawn attention across the region as the Indian Air Force (IAF) prepares for a busy schedule of combat exercises in September and October.

A 17-day NOTAM issued by Indian aviation authorities reserves a large stretch of airspace from September 21 to October 7, 2026. The designated area covers the Jaisalmer–Barmer–Phalodi–Jodhpur belt in western Rajasthan, while airspace near NAL-Bikaner has also been reserved. The restricted zone extends to an altitude of approximately 40,000 feet.

Why Pakistan is watching closely

The timing of the airspace reservation has attracted particular attention in Pakistan because the region is relatively close to the international border.

According to reports citing security sources, Pakistan’s defence establishment has convened an urgent review of the Indian notification and increased vigilance along the border. The assessment is reportedly focused on understanding the nature and scale of the activities planned within the reserved airspace.

Pakistan’s heightened alert comes against the backdrop of continuing military sensitivities between the two countries following last year’s tensions.

However, the issuance of a NOTAM does not by itself indicate that military action is imminent. Such notices are routinely used to inform pilots and other airspace users about temporary restrictions, military exercises and other activities that could affect aviation operations.

Major IAF exercises scheduled

The airspace reservation overlaps with a period of significant activity for the Indian Air Force.

The India-Japan Veer Guardian 2026 exercise is scheduled from September 9 to 21. For the first time, Japanese fighter aircraft are expected to operate from an Indian air base during the exercise. Japan has announced the deployment of three F-2A fighter jets and around 110 personnel.

This will be followed by Tarang Shakti 2026, a multinational air exercise scheduled from September 26 to October 12, with activities centred around Jodhpur and other western Indian air bases.

The back-to-back exercises mean the western sector is likely to witness sustained fighter activity through much of September and into October.

What is a NOTAM?

A NOTAM, or Notice to Air Missions, is an official aviation alert issued to inform pilots, airlines and other airspace users about temporary changes or restrictions affecting flight operations.

Governments can issue NOTAMs for military exercises, temporary airspace restrictions, hazards, navigation changes and other operational requirements.

Therefore, the current 17-day reservation should be viewed primarily as an aviation and operational notification. Its proximity to the Pakistan border and its overlap with major military exercises are the reasons it has attracted heightened attention.

A significant month for the IAF

The upcoming exercises will also provide the IAF with an opportunity to train alongside foreign air forces and test combat coordination in demanding operational environments.

With Japanese F-2A fighters joining Veer Guardian and several international participants expected for Tarang Shakti, September is shaping up to be an important month for India’s air-combat training and interoperability.

For now, the focus remains on the scheduled exercises and the airspace reserved for them, while Pakistan’s security agencies continue to closely monitor developments along the border.
