550s CAN be flown WITHOUT a co-pilot. Ever heard of Cessna Citation 551, better known as the Citation II SP( Single Pilot)?

What does that have to do with this 550 and this pilot?

The 551 IS the same aircraft as 550; same systems…zero difference except for being limited to flying under 30,000 feet and the PIC having to stay on O2 the entire flight above 12,000 ft AGL. Citation IIs CAN be flown in a single pilot operation.

Well of course someone CAN, just not legally in a 550. Which is one reason why someone might choose an uncontrolled airport rather than one with full services.

LEGALLY. You just have to stay below 30, 000 ft, wear oxygen 100% of the time you are above 12,000ft and can’t operate on Part 135. Not familiar with the FARs? 551s ARE 550s. They are certified for single pilot operations. Any other questions? I take it you have a LIMITED background in general aviation?

I believe the Biffel plane was being operated without a legal second which was required.

But whatever you want to believe is fine with me. Maybe you should read the NTSB preliminary report.

Exactly correct Sir.
No, Greg Biffle's jet was not approved to operate with just one pilot. The pilot, Dennis Dutton, was required to have a qualified co-pilot, which Biffle and the other passenger did not meet the necessary qualifications to fulfill. Yahoo thesunchronicle.com
Pilot Requirements for Greg Biffle's Jet
Aircraft Specifications
Model: Cessna Citation 550
Pilot Certification: Required two trained pilots for operation
Pilot Qualifications
Primary Pilot: Dennis Dutton, an experienced pilot
Co-Pilot: Jack Dutton, not qualified to serve as co-pilot for this aircraft
Greg Biffle: Also not qualified to act as a co-pilot
Conclusion
The Cessna Citation 550 required two qualified pilots to operate safely. Neither Jack Dutton nor Greg Biffle had the necessary endorsements to serve as co-pilot, which contributed to the circumstances surrounding the crash.

Already have. Have you read the FARs on WHO can be a co-pilot? Once again, it seems you have extremely limited to NO EXPERIENCE in general aviation.

The FARs are on my side. You MIGHT want to read them.
