I live in an area with a high MSA. (13,000ft), and I am therefore considering buying a PA30/39 Turbo. I would be very interested to hear from Turbo owners as to how they rate their turbo TC’s (warts and all!), and also answers to the following questions:
1) Given that the engines are ‘turbo normalised’, when the turbo is not being used do the engines behave exactly as a non turbo engine does - CHT’s, EGT’s, FF etc?
2) Ignoring wind effects what is the optimum altitude for a turbo TC, and what MP, TAS, FF and CHT’s are owners achieving?
3) Does anyone use LOP in a turbo TC, if so what MP TAS and FF are owners getting? Is there any difficulty keeping CHT’s within limits LOP?
4) I’ve heard that the turbo TC’s are a maintenance nightmare – I would be interested to hear owners experiences, both cost and ease of maintenance.
5) Is there any advice that you can give me regarding the pre purchase test flight and inspection specifically for a turbo TC?
Thanks in advance!
