I met this guy who owns a cirrus and takes me up quite frequently can I log this a dual given as long as I teach him something in flight? He has thousands of hours and just likes someone to go up with him.

Are you giving him instruction?

Yes? Dual given
No? Right seat ballast

Interesting question with a tricky answer.
I think the FAA council has several rulings.
There was one accident investigation of two MEI’s flying together and both logging ME PIC time. One as dual given.
The FAA found them fraudulent as there was no instruction taking place or at least not logged.
With 5000hrs I think you have a hard time proving instruction took place.
Unless you are providing a service such as conducting a Flight review, IPC or a Wings Program flight.
In any case sign his logbook for dual given and what instruction took place.
Make sure his logbook matches yours.
Keep in mind that an incident can occur completely outside of your control. Like a nail on the runway, flat tire and off into the weeds you go.
Who was PIC, who are you, what were you doing in that seat?
The FAA will want to know and so would the insurance company.
Owners can turn on a dime if their toy gets destroyed. And all of a sudden you’re on the hook as you’re the one with the highest rating.
For exactly this reason I would always take the RH seat even as a passenger.
No way I’m getting caught in the backseat during an incident and not being in a position to affect the outcome.
It’s really not worth to risk your career for a handful of hours of “dual given” wink wink....

That's what I said.

Did you sign his logbook showing the training given, enter it in your own, and maintain a training record?

This is a 5,000 pilot who feels the need to have an instructor aboard?

What kind of instruction are you providing? What are you teaching him?

Perhaps the more experienced pilot is new to the “glass” avionics in that particular aircraft whereas the less experienced CFI may have more experience with the aircraft / avionics? You can still teach an old dog new tricks...

And that may account for what - an hour or two - of instruction.

I get the feeling that the OP here would like to log every hour his is filling in the right seat as an hour of CFI and TT.

Plus - unless this 5,000 Cirrus guy is new to this aircraft (don't they have their own training program?) or has new/updated avionics installed that the OP has experience in - this still looks like padding.

Just not worth it for the few extra hours gained. Log it if you want it - just don't try to use it for anything job related.

I once instructed a senior CA on the proper way to open a yogurt cup. Logged a full minute of dual given.

I dunno, aren’t you instructing him in ADM?

5000 hour guy in a cirrus probably needs that!

So what about if I talk to him and we decide that I will be PIC when we fly and he wont log the PIC? He just flies for fun and doesn't really care about logging the time. Even though it is his airplane, he is paying for the fuel, and has much more experience in the plane then me, would that be legal?
