What was the purpose of the no-fly zone over Libya in 2011?

The primary purpose of the no-fly zone established over Libya in 2011 was to protect Libyan civilians from air attacks by the regime of Muammar al-Qaddafi.1

As the conflict between the Qaddafi regime and rebel forces intensified, the regime utilized its military capabilities to stage ground and air assaults against opposition-held areas. Following a resolution passed by the Arab League, the UN Security Council voted on March 17, 2011, to authorize military action, including the enforcement of a no-fly zone, specifically to safeguard the civilian population.1

An international coalition subsequently launched air and missile strikes to disable Libya’s air force and air defense systems, effectively neutralizing the regime's ability to conduct aerial operations against civilians.1
