| If it is necessary to set the altimeter from 29.15 to 29.85, what change occurs? | |
 A. | 70-foot increase in indicated altitude. |
| B. | 70-foot increase in density altitude. |
| C. | 700-foot increase in indicated altitude. |

Pilot's Handbook of Aeronautical Knowledge p 6-4 Since 1 inch of pressure is equal to approximately 1,000 feet of altitude...as the barometric pressure scale is moved, the indicator needles move in the same direction, which is opposite to the reaction the pointers have when air pressure changes. Therefore, an increase of .70" equals 700' increase in indicated altitude. | |
