Certificate privileges

one more thing...
you have a private pilot single-engine and multiengine land... when you do your checkride for the commercial in a 152 (for example) does that give you a multi commercial also? if not, what would be required to do in the multiengine for that commercial rating?
Good question, actually.
For one thing, for initial Commercial certification, you have to at least demonstrate so-called "complex" operations, i.e. controllable prop, flaps and retractable landing gear, in a so-called "complex" airplane, i.e. an aircraft with these items. If you want, you can demonstrate the commercial maneuvers in a "simple" single. So, you cannot take the entire Commercial checkride in a 152.
In any event, if you take and pass the Commercial in a single, you would hold a Commercial Pilot Certificate with Airplane Single-Engine Land privileges, and have Private privileges for Airplane Multiengine Land.
If you held a Private Certificate with and Instrument rating and both single and multiengine privileges, and, barring any "VFR only" restriction on your multi, and, you get your Commercial in the single, you can still fly IFR in the multi, but only as a private pilot.
To have the Private multi privileges removed from your Commercial certificate, you would have to take a Commercial practical in the multi.
Finally, as I understand the rules change from a few years ago, although you received your "complex" signoff, say, in a 320 hp total Twin Commanche (160 hp a side), you cannot act as PIC in the Navajo without a "high performance" signoff. This is because the aircraft in question does not have
an engine of 200 hp or more (although it has 320 total hp

). That is different from several years ago, when a "high peformance" signoff meant either an airplane with an engine with more than 200 hp total
or an airplane with flaps, controllable prop and a retractable landing gear. In other words, let's say you knew someone with a Stearman (a classic biplane with fixed gear and, I believe, a 450 hp radial) or a Cessna 195 (a classic fixed-gear high-wing with a similar radial) who was willing to give you a high performance signoff in his airplane, you could recieve it without demonstrating flap and gear operation. "Complex" airplane was not in the official FAA lexicon in those days. Which meant that my 360 total hp Seminole trainees (180 hp a side) received a "high performance airplane" signoff from me prior to going for their Private multis, and which covered controllable prop and retractable gear as well as the horsepower requirement. In my .02 opinion, the rules change makes no sense. But, that's only my .02.
Hope the above explanation helps.
