What is the primary purpose of aircrew being authorized to carry handguns?

The primary purpose of aircrew being authorized to carry handguns is for anti-jacking purposes. This measure is instituted to provide a means of defense against potential hijacking scenarios, where an unauthorized individual may attempt to gain control of the aircraft. In the event of a hijacking, having armed personnel onboard can deter such actions and protect both the crew and passengers onboard.

While the idea of defending against aggressive passengers or intimidation may seem plausible, these do not align with the overarching reason for this policy. The focus is clearly on neutralizing serious threats to flight security, primarily in situations where someone may attempt to take control of the aircraft. The need for armed response during turbulence is also not a relevant factor for the authorization to carry firearms.
