“…Its main goals are to measure lightning strike parameters, to determine entry and exit points on the aircraft structure, and to assess the possible structural damage. It was comprehensively described in a series of publications (de Boer et al, ; Hervé et al, ; Stelmashuk et al, , ; van Deursen, ; van Deursen & Stelmashuk, ; Zwemmer et al, ). The ILDAS system was extended with two LaBr3 40 × 40 mm 2 cylindrical scintillation detectors.…”

An Airbus A340 aircraft flew over Northern Australia with the In‐Flight Lightning Damage Assessment System (ILDAS) installed onboard. A long‐duration gamma ray emission was detected. The most intense emission was observed at 12 km altitude and lasted for 20 s. Its intensity was 20 times the background counts, and it was abruptly terminated by a distant lightning flash. In this work we reconstruct the aircraft path and event timeline. The glow‐terminating flash triggered a discharge from the aircraft wing that was recorded by a video camera operating onboard. Another count rate increase was observed 6 min later and lasted for 30 s. The lightning activity as reported by ground networks in this region was analyzed. The measured spectra characteristics of the emission were estimated.

− In the EU FP6 project ILDAS a prototype In-flight Lightning Damage Assessment System is developed for passenger aircraft and helicopter. The project aims to localize the attachment and the severity of the strokes during flight to assist maintenance. A database of events will be constructed to substantiate requirements for aircraft lightning immunity. Inductive magnetic field sensors are put at various positions on the aircraft. The sensors are followed by passive/active integrators to deal with the large dynamic range and bandwidth, and by high speed data conversion/storage. The paper focuses on design and tests of three types of sensors.

“…It was shown that the window sensor output reliably reproduces the sensor with 50 Ω damping resistors and 50 Ω resistor at the output sensor without damping resistors and 50 Ω resistor at the output injected current. The result of this test will be presented in [4]. The impedance of window sensors with and without damping resistors is shown in Fig.7.…”

“…A properly designed shield can filter the short time magnetic fields with big amplitudes. The preliminary solid state sensor selection has been described in [3] and the shield calculation and the solid state sensor test results have been presented in [4]. These will not be discussed here.…”
