It is shown that the probability is 1/g that the predicted future position of the airplane will lie in a volume surrounding the true future position and having a content which varies as the square of the time of flight and the product of the errors in the two angular rates provided by the director. From an analysis of the performance of service directors it is found that for fire against modern planes at high altitudes, the dimensions of this volume are large compared with the corresponding components of the dispersion of the points of burst and that therefore the probability of hitting varies inversely as this volume.
It is pointed out that there is an urgent need for directors of greater precision to augment the probability of hitting.as well as for more accurate height finders.
The purpose of this report is to make a study of the combined detects of the errors of the height finder and the director on the probability of hitting an airplane. In making this study the conditions most favorable to fire control are assumed; the airplane Is assumed to be moving at constant altitude with a constant speed and direction.
