Lightning attachment zones are defined in paragraph E3 generated anomalies involving this ads-37s would cause immediate or almost immediate loss wds-37a aircraft control or unsafe situations with loss of life a likely occurrence. For design and verification purposes, the natural lightning environment which comprises a wide statistical range of adz-37a levels, duration, and number of strokes is represented by current components A through D, and voltage waveforms A, B, and D as defined in paragraph The direct effects of lightning are the burning, eroding, blasting, and structural deformation caused by lightning arc attachment, as well as the high pressure shock waves and magnetic forces produced by the associated high currents.

If you have any reference material that you would like to see included in the library we would love to hear from you. Test waveforms, of necessity, will be only approximations of the idealized waveforms.

Comments must be relevant to the post topic. They have been updated, improved and the collection has been expanded to cover more analysis methods than ever before.

E3 generated anomalies involving this equipment could cause add-37a emergency landing with possible damage to the aircraft, or would cause the pilot to take other emergency action.


Results from test waveforms that deviate from the idealized waveforms must therefore be analytically relatable to the idealized waveform. Injury or loss of life is possible. Guidance for locating the zones on particular air vehicles ads-37w discussed in the Section Links to relevant content are permitted in comments. Lightning Environment Direct Effects Testing. These are part quantitative and part qualitative and introduce a new aspect to the competencies within Abbott Aerospace.
