The flight navigation instrument (based on GPS) from the Blackhawk helicopter recorded an altitude height of 1,750m above mean sea level initially when it has not reached inland. After 10 kilometers inland and upon approaching the Zambales mountain range flight skipper adjusted his altitude to 1,850m but his visibility is nil due to a sea of clouds and fog. He looked at a local LGU map and saw 1790m elevation of the mountain approach.Will the chopper reach his destination while maintaining an altitude of 1850m?
