Thanks to everyone that replied
Thanks for the information.
Our company is a US FAR 91 corporate operation and therefore not subject to OpSpecs. We do try to adhere to industry "best practices", hence the audit and the IS-BAO certification.
The problem I have seen is that some of the recommendations from the audit team and the IS-BAO staff are somewhat questionable with regard to a basis in regulation or operating procedures in the industry. The 30 minute rule for takeoff alternate is an example. It's not a bad idea, but should limit ourselves beyond what the FAR 121 carriers require? That's why I wanted to know whether OpSpecs typically require less than one hour still air distance with OEI? From what I'm hearing, this is not the case.
As a FAR 91 operator, we're not bound by the same operating rules as a FAR 121 or 135 operator holding out for common carriage. But I strongly believe that adherance to the 121 and 135 regulations is the fiirst line of risk managment and the base line for best practices in the industry. It can be prudent to go beyond these regulations, as the OpSpecs occasionaly do.
Thanks again for your help. I will continue to monitor this thread for more input.
