No, your incorrect. The ATP requirement to act as PIC under 135 is for passenger carrying operations and then only for:

1)Turbojet airplanes.
2)Airplanes having a passenger-seat configuration, excluding each crewmember seat, of 10 seats or more.
3)Or multiengine airplanes in a commuter operation as defined in part 119 of this chapter.

All other 135 operations in a multiengine airplane require only a Commercial AMEL.

Maybe next time before you slam someone for not looking at the regs, you should take a look at them yourself first. Just a suggestion.

Maybe I'm missing something, but didn't you ask if you were an ATP in the first post?

Thanks for the backup Johnnysnow!

I was basing my answer on the context of a 135 single pilot operator which is what slipped was talking about, not the big passenger operators.

My pleasure.

You're online, you've got the regs available.

(7)
(b) Notwithstanding the provisions of paragraphs (a)(1) and (2) of this section, an applicant for an airline transport pilot certificate or an additional rating to an airline transport certificate may take the practical test for that certificate or rating with an expired knowledge test report, provided that the applicant:
(1) Is employed as a flight crewmember by a certificate holder under part 121, 125, or 135 of this chapter at the time of the practical test and has satisfactorily accomplished that operator's approved—
(i) Pilot in command aircraft qualification training program that is appropriate to the certificate and rating sought; and
(ii) Qualification training requirements appropriate to the certificate and rating sought; or
(2) Is employed as a flight crewmember in scheduled U.S. military air transport operations at the time of the practical test, and has accomplished the pilot in command aircraft qualification training program that is appropriate to the certificate and rating sought.

No place does it say you can only extend a 121 written while working for a 121 carrier or a 135 while working for a 135. Can you find me a 125 written? You're covered as long as you stay employed.

The SEL ATP is good for getting the ATP if your 24 months is running out and none of the above applies to you. Much cheaper to do the ride SEL then do the MEL as an add on whenever.

Now I am confused, just for the record I am comm. not ATP

1. No
2. Thorough, not difficult. Know the regs, systems, and be IFR current.
3. Yes.

You'd better brush up on your FARs or you're in trouble.

Please accept my most humble apologies. My Part 135 experience is exclusively 1,2 and 3 and I did not research the regs that did not apply to my experience. I did not mean to "slam" anybody, however my post was short and not very helpful to the thread starter or anybody else. I'll do better next time...

I thought it was ok
