Pilots warned against flying planes close to Mayon 

AVIATION authorities warned pilots against flying their planes close to the peak of Mayon Volcano because of the danger posed by its ash eruptions.

In its notice-to-airmen (notam) on Sunday, the Civil Aviation Authority of the Philippines (CAAP) said the “existence and horizontal/vertical extent of volcanic ash cloud” may endanger all aircraft passing near the area and advised against flying close to the summit.
