Aerial parachute shrapnel with laser range-finding fuze is in heeling condition in the air generally, it results in the laser furze's optical path and distance measurement increase. Eventually, this would lead to the actual bombing height range below the set height range of the best aerial bombardment. To correct the high-altitude error because of the elastic axis is in heeling condition, a method based on gravity was put forward. The experiment result shows that the correction error does not exceed 8.1% when elastic axis angle is less than 50° and the method has reference value in height correction of the aerial parachute shrapnel to some extent.
