• Under the pre-notification of flight testing of ballistic missiles agreement signed in 2005, a country must provide the other an advance notification on flight test it intends to take for any land or sea launched, surface-to-surface ballistic missile.
• Before the test, the country must issue Notice to Air Missions (NOTAM) or Navigational Warning (NAVAREA) to alert aviation pilots and seafarers, respectively.
• Also, the testing country must ensure that the launch site is not within 40 km, and the planned impact area is not within 75 km of either the International Boundary (IB) or the Line of Control (LoC).
• The planned trajectory should not cross the IB or the LoC and must maintain a horizontal distance of at least 40 km from the border.

A 

• The testing country must notify the other nation “no less than three days in advance of the commencement of a five day launch window within which it intends to undertake flight tests.

 Q What is the recent case of misfire?

A 

• Neither country has spelt this out; Pakistan has only called it a “supersonic” missile.
• Some experts have speculated that it was a test of one of India’s top missiles, BrahMos, jointly developed with Russia.
