Turboprop Tips
Hi !
I have recently started flying a PT6A powered machine after thousands of hours flying pistons.
I have been looking for a reference book that can fill me up with info on the finer points of operating turboprops. Any suggestions ?? (Ive tried Advanced Aircraft Systems, and Turbine pilots flight manual - neitehr really spend much time on turboprops).
Some specific questions that pop to mind are:
1. Derated Vs Flat rated - What does it really mean ?? Whats the operational difference to me ?
2. Starting problems - Hot, hung starts etc. Is batterty power the only issue ??
3. Why am I told to turn the genny on the operating engine off when starting the other ??
4. Should I be worried about autofeather failing in an engine failure after TKOF scenario ?
5. The acft is certified under SFAR41 - what do I need to know about this ?? It is considered a small aircraft in my country (under 5700kg) - DOes SFAR41 have any significance ?
6. Best ways to detect water in the fuel ?? ******ed if I can tell if theres water after a fuel drain. Is water as big a problem in JET fuel ?
7. What is the relationship between torque and Np ? Why does a change in Np effect torque ?
8. Flight idle/Beta/ground range - What are they all about ?
Any other hints/tips or things i should be aware of ?? Common problems (if any) with PT6A 's??
Many thanks !
