I've always had a few curious questions about engines that I wonder if anyone here can answer?
1.) It is my understanding that the main engines are started using hydraulic pressure from the APU -- is that correct? How does one start a jet engine without an APU? Is there an electric starter?
2.) What kind of engine is the APU?
3.) I know that there exist single engine turbo-prop aircraft -- are there any single engine jet aircraft in use?
4.) Are small multiengine turboprop aircraft much cheaper to produce and operate than small multiengine jet aircraft? Is this why choosing between for example a DH8 and a Canadair jet is a big difference?
Thanks to anyone who can enlighten me!
