APPENDIX I TO PART 141 - ADDITIONAL
AIRCRAFT CATEGORY AND/OR CLASS
RATING COURSE
1. Applicability. This appendix prescribes
the minimum curriculum for an additional
aircraft category rating course or an additional aircraft class rating course required
under this part, for the following ratings:
(a) Airplane single-engine.
(b) Airplane multiengine.
(c) Rotorcraft helicopter.
(d) Rotorcraft gyroplane.
(e) Powered-lift.
(f) Glider.
(g) Lighter-than-air airship.
(h) Lighter-than-air balloon.
2. Eligibility for enrollment. A person must
hold the level of pilot certificate for the additional aircraft category and class rating
for which the course applies prior to enrolling in the flight portion of an additional aircraft category or additional aircraft class
rating course.
3. Aeronautical knowledge training.
(a) For a recreational pilot certificate, the
following aeronautical knowledge areas
must be included in a 10-hour ground training course for an additional aircraft category
and/or class rating:
(1) Applicable regulations issued by the
Federal Aviation Administration for recreational pilot privileges, limitations, and
flight operations;
(2) Safe and efficient operation of aircraft,
including collision avoidance, and recognition and avoidance of wake turbulence;
(3) Effects of density altitude on takeoff
and climb performance;
(4) Weight and balance computations;
(5) Principles of aerodynamics, powerplants, and aircraft systems;
(6) Stall awareness, spin entry, spins, and
spin recovery techniques if applying for an
airplane single engine rating; and
(7) Preflight action that includes how to
obtain information on runway lengths at airports of intended use, data on takeoff and
landing distances, weather reports and forecasts, and fuel requirements.
(b) For a private pilot certificate, the following aeronautical knowledge areas must
be included in a 10-hour ground training
course for an additional class rating or a 15hour ground training course for an additional aircraft category and class rating:
(1) Applicable regulations issued by the
Federal Aviation Administration for private
pilot privileges, limitations, and flight operations;
(2) Safe and efficient operation of aircraft,
including collision avoidance, and recognition and avoidance of wake turbulence;

(3) Effects of density altitude on takeoff
and climb performance;
(4) Weight and balance computations;
(5) Principles of aerodynamics, powerplants, and aircraft systems;
(6) Stall awareness, spin entry, spins, and
spin recovery techniques if applying for an
airplane single engine rating; and
(7) Preflight action that includes how to
obtain information on runway lengths at airports of intended use, data on takeoff and
landing distances, weather reports and forecasts, and fuel requirements.
(c) For a commercial pilot certificate, the
following aeronautical knowledge areas
must be included in a 15-hour ground training course for an additional class rating or a
20-hour ground training course for an additional aircraft category and class rating:
(1) Applicable regulations issued by the
Federal Aviation Administration for commercial pilot privileges, limitations, and
flight operations;
(2) Basic aerodynamics and the principles
of flight;
(3) Safe and efficient operation of aircraft;
(4) Weight and balance computations;
(5) Use of performance charts;
(6) Significance and effects of exceeding
aircraft performance limitations;
(7) Principles and functions of aircraft systems;
(8) Maneuvers, procedures, and emergency
operations appropriate to the aircraft;
(9) Nighttime and high-altitude operations;
and
(10) Procedures for flight and ground training for lighter-than-air ratings.
(d) For an airline transport pilot certificate, the following aeronautical knowledge
areas must be included in a 25-hour ground
training course for an additional aircraft
category and/or class rating:
(1) Applicable regulations issued by the
Federal Aviation Administration for airline
transport pilot privileges, limitations, and
flight operations;
(2) Meteorology, including knowledge and
effects of fronts, frontal characteristics,
cloud formations, icing, and upper-air data;
(3) General system of weather and NOTAM
collection, dissemination, interpretation,
and use;
(4) Interpretation and use of weather
charts, maps, forecasts, sequence reports, abbreviations, and symbols;
(5) National Weather Service functions as
they pertain to operations in the National
Airspace System;
(6) Windshear and microburst awareness,
identification, and avoidance;
(7) Principles of air navigation under instrument meteorological conditions in the
National Airspace System;
(8) Air traffic control procedures and pilot
responsibilities as they relate to en route operations, terminal area and radar operations,
