Observer-target distance - definition of observer-target distance by The Free Dictionary http://www. thefreedictionary. com/observer-target+distance Printer Friendly.
NOTE:? When the observer sees a target, he should notify the RTO so the RTO can begin the CFF while the target location is determined. The RTO sends the information as it is determined, instead of waiting until a complete CFF has been prepared.
d. Time of Flight. Time of flight (TOF) is announced to the nearest whole second. It is announced to observers when targets are engaged with Copperhead, when moving targets are engaged, when conducting high-angle missions, when using an aerial observer, or when requested by the observer. For example, the RATELO would announce TIME OF FLIGHT 34 SECONDS.
Transmit corrections to the FDC in meters. The initial correction should bracket the target in range. The adjustment phase of a fire mission would resemble the example shown in figure 061-283-6003-6. Deviation correction should be made to keep the rounds on the observer target.
