Well the good news is you can be both. I have been in the aerospace field for many years, and the last 10 years working directly on UAV or Drones. I worked with many software engineers in that field, it takes a lot of digital designing to make them go. You would do best to take some aerospace courses and some software courses then decide what you like best. If you keep that in mind you should be fine when applying to any aerospace company.
