Yes, you should follow the import guidelines, as linked by Matt Williams.
Note there has been previous discussion of importing data from 
ourairports.com, and whether it is a good idea. See for example this 

Firstly, its not clear whether the data from OurAirports is under a 
suitable licence. They say it is "public domain", but it seems some of 
it may be derived from Google Maps, or other copyright sources.

Also, I don't know how accurate the data is. Some people in the previous 
thread were saying some of the airports are just fields.

Also, I'm not sure what you mean by "navigation aids". Things which do 
not physically exist on the ground are not usually mapped in OSM. See
