A commercial pilot with DC-3 and DC-9 type ratings completes a flight test for an Airline Transport Pilot Certificate in a B-727. What privileges can they exercise?

The correct answer indicates that the pilot will hold an Airline Transport Pilot (ATP) certificate for the B-727, along with the privileges to operate the DC-3 and DC-9 as well. This is because when a pilot successfully completes the necessary flight tests and meets the requirements for an ATP certificate in a specific aircraft (in this case, the B-727), they gain ATP privileges for that aircraft type.

Additionally, since the pilot already possesses type ratings for the DC-3 and DC-9, these ratings remain valid, allowing them to act as pilot-in-command under the privileges of a commercial pilot for those aircraft, even though they have now obtained an ATP certificate.

This illustrates the concept that obtaining a higher-level certificate (ATP) does not eliminate or negate the pilot's previous certifications for other aircraft; rather, it enhances their qualifications and allows them to operate a broader range of aircraft under the ATP privileges. Therefore, the pilot can operate the B-727 as an ATP, while also retaining the ability to operate the DC-3 and DC-9 under their commercial privileges.
