The most common scales for model airplane hobbyists are 1/48 (1¾” or 31. 8 mm) and 1/72 (1” or 25mm). [1] X Research source

Look at layouts for airports in the UK through NATS (http://www. nats-uk. ead-it. com/public/index. php%3Foption=com_content&task=blogcategory&id=6&Itemid=13. html) and in the US through Federal Aviation Administration (https://www. faa. gov/airports/runway_safety/diagrams/).

After you’ve sketched your design on the base, place it on a table so you can start adding your structures.

Build simple, large gray buildings with double doors large enough to accommodate an airplane for your hangars. Terminals can be simple, long structures with jetways on the side of the terminal facing the runways. Make two levels on the side facing the parking lot, with multiple doors for passengers. Parking garages can match real-world parking garages with multiple levels of parking lots stacked in a building. Position the terminals on your base according to where you have them in your design.

Aprons are the same as ramps.

Create one taxiway for each apron.

Make at least one runway if you’re designing your own airport. If you’re basing your model on a real-world airport, make the same number of runways found at that airport. Number the runways using the block, geometric font used for runway designators. You can see examples of this font at https://www. tc. gc. ca/eng/civilaviation/regserv/cars/part3-standards-325-325-160. htm.

Put down the foam first, then spray it lightly with some white glue if you don’t want to crumble the foam. If you will crumble the foam, also paint the board under the grassy sections green before adding the foam to make the grass more vibrant.

Cover the tops of small twigs covered in lichen and glue the twigs to the base for trees. [8] X Research source

Make stop signs, parking signs, and signs indicating the location of aprons and jetways on the runways. Add names or other designators to your buildings. Write them freehand or use a stencil with paint or permanent marker.

Find miniature cars, tankers, fire engines, shuttle buses, and other vehicles that belong at the airport. Get these in your scale and place them around the airport.
