航空工程师在飞机上工作;也就是说，他们设计和测试在地球大气层中飞行的车辆。无人驾驶飞机，直升机，商用飞机，战斗机和巡航导弹都属于航空工程师的职权范围。航天工程师负责处理离开地球大气层的车辆的设计，开发和测试。这包括各种军事，政府和私营部门应用，如火箭，导弹，航天器，行星探测器和卫星。这两个子领域在他们需要的技能组合中相当重叠，通常两个专业都在大学的同一部门内。航空航天工程师的最大雇主往往拥有涉及航空和航天的产品和研究。波音，诺斯罗普格鲁曼，NASA，SpaceX，洛克希德马丁，JPL（喷气推进实验室），通用电气和其他几家公司也是如此。航空航天工程工作的性质差异很大。一些工程师将大部分时间花在使用建模和仿真工具的计算机前。其他人则更多地在空中隧道和现场测试比例模型以及实际的飞机和太空飞行器中工作。航空航天工程师参与评估项目提案，计算安全风险和开发制造流程也很常见。

Aeronautical engineers work on airplanes; that is, they design and test vehicles that fly in the Earth’s atmosphere. Drones, helicopters, commercial aircraft, fighter jets and cruise missiles are among the aviation engineers’ terms of reference. The aerospace engineer is responsible for the design, development and testing of vehicles leaving the Earth’s atmosphere. This includes a variety of military, government and private sector applications such as rockets, missiles, spacecraft, planetary detectors and satellites. These two sub-areas overlap quite a bit in the skill set they need, usually both in the same department of the university. The largest employers of aerospace engineers often have products and research involving aerospace and aerospace. Boeing, Northrop Grumman, NASA, SpaceX, Lockheed Martin, JPL (Jet Propulsion Laboratory), General Electric and several other companies are also the same. The nature of aerospace engineering work varies widely. Some engineers spend most of their time in front of computers that use modeling and simulation tools. Others work more in air tunnels and on-site test scale models as well as on actual aircraft and spacecraft. It is also common for aerospace engineers to participate in evaluating project proposals, calculating security risks and developing manufacturing processes.
