An aerodrome is a small airport used by light planes. This proposes to use the 'jet' icon only for airport and distinguish aerodrome User:David.earl

Technically, "aerodrome" is a very general term - pretty much anywhere aircraft take/off or land. From section 1.1 Definitions, of Annex 14 to the Convention on International Civil Aviation, Volume I, Aerodrome Design and Operations:

Aerodrome. A defined area on land or water (including any buildings, installations, and equipment) intended to be used either wholly or in part for the arrival, departure and surface movement of aircraft.

This even includes an area of water for sea/float planes. "Airport" is a bit more difficult to define but is probably best reserved for land aerodromes intended for commercial flights or regular international flights.

I would suggest the use of the word "airfield" for a small aerodrome for light aircraft. Some people think "airfield" specifically means a grass field with no hard runways but that's not the way the term is commonly used in aviation - if you want to say an airfield has no hard runways you'd probably refer to it as a "grass airfield" or somesuch.
