I believe we can make a reasonable distinction between major classes<br>
of aerodromes:<br>
<br>
1) Airstrips without buildings or any other developed features<br>
<br>
2) Developed general aviation aerodromes which do not offer any<br>
regularly scheduled public, commercial passenger service<br>

3) Commercial airports which offer regularly scheduled commercial<br>
passenger service<br></blockquote><div><br></div><div>I'd go along with these definitions</div><div><br></div><div><u>Airstrips</u> are simple grass or dirt strips with no, or very limited, facilities, that may be either private, or open to all aircraft.</div><div><br></div><div><u>Aerodromes</u> are established facilities, usually with a sealed runway/s & taxiways & other facilities eg hangars & fuel, but which don't operate commercial services. These would often be flying clubs eg <a href="https://www.gcsfc.org.au/">https://www.gcsfc.org.au/</a></div><div><br></div><div><u>Airports</u> are anything that operate what is called RPT: </div><table class="gmail-horiz" style="box-sizing:border-box;border-collapse:collapse;border-spacing:0px;margin:1em 0px;width:482.727px;font-size:16px;color:rgb(95,95,95);font-family:"Open Sans",sans-serif;word-spacing:-0.8px"><tbody style="box-sizing:border-box"><tr style="box-sizing:border-box;color:rgb(76,76,76);background-color:rgb(242,242,242);border-width:0px 0px 2px;border-top-style:initial;border-right-style:initial;border-left-style:initial;border-top-color:initial;border-right-color:initial;border-left-color:initial;border-bottom-style:solid;border-bottom-color:white"><td style="box-sizing:border-box;padding:0.625em 0.9375em;border-width:0px 0px 0px 2px;border-top-style:initial;border-right-style:initial;border-bottom-style:initial;border-top-color:initial;border-right-color:initial;border-bottom-color:initial;border-left-style:solid;border-left-color:white;vertical-align:top"><p style="box-sizing:border-box;margin:0.75em 0px;line-height:1.8em"><strong style="box-sizing:border-box">Regular Public Transport</strong></p></td><td style="box-sizing:border-box;padding:0.625em 0.9375em;border-width:0px 0px 0px 2px;border-top-style:initial;border-right-style:initial;border-bottom-style:initial;border-top-color:initial;border-right-color:initial;border-bottom-color:initial;border-left-style:solid;border-left-color:white;vertical-align:top"><p style="box-sizing:border-box;margin:0.75em 0px;line-height:1.8em">Flight operations performed for remuneration and conducted to fixed schedules over specific routes, and on which seats and/or cargo space is available to the general public.</p></td></tr></tbody></table><div>It doesn't matter whether it's the above mentioned Barra or Heathrow / LAX / Frankfurt - if it operates RPT it's an airport, if it doesn't, it's not. Also note that cargo is still classified as RPT, so a cargo-only airport, would still be an airport.</div><div><br></div><div>I'm not certain how best to work places such as Newcastle Airport <a href="https://en.wikipedia.org/wiki/Newcastle_Airport_(New_South_Wales)">https://en.wikipedia.org/wiki/Newcastle_Airport_(New_South_Wales)</a> / RAAF Williamtown <a href="https://en.wikipedia.org/wiki/RAAF_Base_Williamtown">https://en.wikipedia.org/wiki/RAAF_Base_Williamtown</a>, which share a common runway, with the civillian terminal on one side & military operations on the other - 2 tags, one airway=airport & the other military=airbase?</div><div><br></div><div>Thanks<div><br></div><div>Graeme</div></div></div></div>
