As you look to interview for an Aircraft Mechanic role with Air New Zealand, you can certainly expect some technical questions like this to pop up. Whether you have the direct experience working with an IDG or not, your interviewer will at least be looking to hear that you are familiar with the fact that they are used on the Air New Zealand fleet to help supply electrical power. They'll also look to hear that you have knowledge of the IDGs requirements for maintenance on the oil within the system as a regular part of the work that you'll perform. If you do have direct experience, be sure to talk about that as you answer this question.
