 What is the Target Motion Analysis(TMA) formula for determining target course? Reciprocal of target brg minus angle ont the bow(R-Ab) What is the primamry objective of establishing a target's brg. rate? to calculate the targets c/s and spd. what is the foundation of all TMA plots and solutions? Time BRG Plot when was the highest brg drift rate of a passive target observed? At targets CPA Assuming own ships c/s and spd are steady, wha does a radical increase or decrease in passive target brg drift signify? Target c/s , spd change what TMA plot uses matches target assumed spd using spd strips to plotted faired brg to solve for target c/s and rng? Strip plot Assuming own ship c/s and spd are steady, what does a change in the direction of a passive targets brg drift mean? Target c/s change what is used to denote a dead-in-the-water(DIW)contact on the geographic plot? a 500 yd radius circle centered on the contact. How is an engaged hostile surface track indicated in NDTS? a horizontal bar across the middle of a full diamond symbol. How is a hostile air contact, which is assigned to an interceptor displayed in NTDS? Upper half diamond with half horizontal bar across bottom of the symbol what symbology denotes a neutral track in NTDS-A? A green cross What is the miniumum # of plots needed to obtain an initial c/s and spd.? 3 plots normally two min.
