ROCIS Flight Parameters and Range Information

General Information:

Note: The range of 800 nmi is not consistent with 140 kt plane speed and 5 hr flights (700 nmi). Similarly, the nominal range of 650 nmi is not consistent with 140 kt speed for 4 hours (560 nmi). So we have the following possible ranges:

For our initial planning, two types of flight paths are considered: Equilateral triangle paths, with side length R/3 nmi (R is the range), and out-and-back paths, each of length R/2 nmi.
