What are the protocols of flying over conflict areas? Apparently Malaysia Airlines Flight 17 used a general airway over the east of Ukraine, which currently is 'in conflict'.

What are the 'normal' procedures regarding (not) flying over conflict areas? Who is responsible for an up-to-date risk assessment? Who advises? Who makes the (final) decision?
This is horrendous Incident, and my heart goes out to the victims Families who lost their loved ones.



The FAA filed a special Warning flying over Crimea back in April but apparently not where the airplane went down.

The procedure is to avoid flying over (Dead/No fly Zones) which Aviation Authorities are responsible in providing to the Airline companies so they can adjust their flight plans.
