31. Eventually, it was found that low pressure ducting in the # 1 engine was cracked. 32. Alternatively, it may involve ducting exhaust gases along the wing's entire trailing edge. 33. Intake air ducting and exhaust system are modified to improve response and reduce the exhaust gas backpressure. 34. The inerting process prevents build-up of potentially explosive materials inside the chamber or exhaust ducting . 35. Ideally, a relatively flat land path between the transmitter and receiver is ideal for tropospheric ducting . 36. Cable ducting is not needed in smaller power facilities where copper cables are less than 25mm 2. 37. The insulation will shield the ducting so the moisture will not condense and run back to the fan. 38. The kitchens and bathrooms were vertically aligned allowing simple ducting for services and the Garchey waste disposal system. 39. In the older steel pressure vessel design, boilers and gas ducting are outside the concrete biological shield. 40. This was fed through ducting in the leading edge of the wings and up to the rotor head.
