Ok, I now see how "Type" is being interpreted. The application of type is inconsistent throughout the manual. Some can be interpreted as aircraft with similar handling characteristics, stall speed, configuration etc. however there are other references to Type which are specific to a particular manufacturer and model. Try doing a word search of the .pdf and you'll see what I mean.
The FAA define type as follows:
Type:
(1) As used with respect to the certification, ratings, privileges, and limitations of airmen, means a specific make and basic model of aircraft, including modifications thereto that do not change its handling or flight characteristics. Examples include: DC–7, 1049, and F–27; and
(2) As used with respect to the certification of aircraft, means those aircraft which are similar in design. Examples include: DC–7 and DC–7C; 1049G and 1049H; and F–27 and F–27F.
(3) As used with respect to the certification of aircraft engines means those engines which are similar in design. For example, JT8D and JT8D–7 are engines of the same type, and JT9D–3A and JT9D–7 are engines of the same type.
