Transit Editor you should calculate the transit time 157 Chapter 12 Effort Allocation SRUs and the SRU Manager before modifying the SRU s search pattern so that your modifications are not lost However modifying the SRU s search pattern in such a way that its CSP ESP or time on scene is altered means that a previously calculated transit time is no longer valid If the change is not significant the estimated transit time will likely still be useful If it is significant however and you are relying on the Transit Editor to determine time on scene or on scene endurance it might be wise to measure the new transit distance with the linear range ruler and use this distance and the SRU s transit speed to calculate the actual transit time and time on scene and compare it to the estimated values Alternately you could save the scenario recalculate the transit time and make note of the new estimate and time on scene and then reload the SRUs by selecting Reload from the File menu and then SAR Units from the menu of scenario components when it appears Once the SAR Units are reloaded subtract the estimated transit time from the SRU s total endurance enter this new value into the SRU Endurance field on the Calculations tab of the SRU Manager and the new CSP time on scene into the Time field on the Details tab and do not use the Transit Editor to calculate transit time 158 Chapter 13 Effort Allocation Search Patterns CAN
