Single engine add-on commercial can be done in anything since you already met the requirement for the Multi.
As I understood things (as well as my DPE at the time of my checkride last year), it used to be that for the CFI-A you did need to do at least a portion of the checkride in a complex. I noticed that the wording changed a bit in PTS FAA-S-8081-6C. Is this not required anymore? Seems that the requirement has been removed to me.
According to the old PTS:
FAA-S-8081-6B
Aircraft and Equipment Required for the Practical Test
The flight instructor applicant is required by 14 CFR part 61, section
61.45 to provide an airworthy, certificated aircraft for use during the
practical test. This section further requires that the aircraft must:
1. be of U.S., foreign or military registry that is of the category,
class, and type, if applicable, for the certificate and/or rating for
which the applicant is applying;
2. have fully functioning dual controls except as provided in 14 CFR
section 61.45(c) and (e); and
3. be capable of performing all appropriate TASKs for the flight
instructor rating sought and have no operating limitations, which
prohibit the performance of those TASKs. A complex airplane
must be furnished for the performance of takeoff and landing
maneuvers, and appropriate emergency procedures. A complex
landplane is one having retractable gear, flaps, and controllable
propeller. A complex seaplane is one having flaps and
controllable propeller.
Now the new PTS (FAA-S-8081-6C)reads:
Aircraft and Equipment Required for the Practical Test
The flight instructor applicant is required by 14 CFR part 61, section
61.45 to provide an airworthy, certificated aircraft for use during the
practical test. This section further requires that the aircraft must:
1. be of U.S., foreign or military registry of the same category, class, and
type for the certificate and/or rating for which the applicant is applying;
2. have fully functioning dual controls except as provided in 14 CFR part 61,
section 61.45(c) and (e); and
3. be capable of performing all appropriate TASKs for the flight instructor
rating sought and have no operating limitations, which prohibit the
performance of those TASKs. A complex landplane is one having a
retractable landing gear, flaps, and controllable propeller. A complex
seaplane is one having flaps, floats, and a controllable propeller.
Airplanes that are equipped with a full authority digital engine control
(FADEC) system are considered to have a controllable propeller.
Anyone know more about this?
