FIG. 1 shows an efficient flight path for airframe 10 with camera 16 flying along a transmission line utility corridor containing towers 40, 42, and 44. Between the towers the airframe is in a fast linear glide 18 to check the right of way for encroachment. Abreast of tower 42, the airframe spirals down 20 with power plant 11 off to take more detailed pictures. When the tower inspection is complete, power plant 11 is turned on to start a power climb 22 back up to prepare for glide 24 to the next tower 44, where the airframe again spirals down 26 for a closer inspection. On the return flight, a close-in conductor inspection is flown in catenary arcs with glides 28, 32 on the downslope and power climb 30, 34 on the upslope.
