My understanding is that the CJ1 and CJ2 SP are both Single Pilot Jets. my question is for those of you who fly those jets. If you are sitting right seat in a CJ1 and not type rated, how do you log time if you cant log it as SIC or PIC since one is not required?

I think you may have just answered your own question:

You're not typed, you're not required, you don't log it.

However, if the PIC is also a CFI, you may be able to log dual received.

You cant even log it as total time? Why would anyone want to fly right seat in a CJ1 or 2 if they cant log it?

What kind of time would you log? Passenger?

It's still a good source of experience.

Why not total time?

It depends on the type of opperations. If the opperation requires a SIC (FAR 135 for example) then you can log it.

Is the PIC approved for single pilot ops? (C525S rating on his certificate) If not, then they are required to have an SIC. This means you would be acting as a required crewmember.

C525 Type Rated PIC-----Needs an SIC to fly

C525S Type Rated PIC-----Can fly single pilot

I would say that if the PIC agrees, that for part 91 legs log it as Dual received. Ofcourse the PIC will need to be an ATP to do so, unless they're a CFI. But Gauley is correct. The Citation series only have single pilot waivers, which requires the pilot to demonstrate single pilot skills. The aircraft itself is not single pilot certified.

Does the FAA require two pilots in the CJ. Is the single pilot qualification in addition to the basic type rating? All the ones that I have seen being operated have been with two pilots.

The "ATP" rule only applies to pilots working for a company in the business of air transportation (IE for hire transport of passengers or 135/121). Any part 91 flying would have to be done with an MEI.

As for the SP Citation ratings, some of the Citation line is certified for single pilot operations (aircraft wise), others are not.

IIRC, the Mustang, CJ1, and CJ2 are single pilot certified from the get go. The Citation 500 series (Bravo, Ultra, Encore), and the CJ3 all have SP waivers.
