I'm excited about this push. One interesting note is how this entire project has been 'in flight' for 30+ years almost cancelled with PAFI and then with then with recent pressure to close airports (namely KRHV) with leaded fuel as the lighting rod the FAA has now accelerated to “progress at the speed of light.” "He added that the accelerated commitment reflects new urgency arising from the FAA’s awareness that some local governments are taking action to ban leaded avgas from being used at airports in their jurisdictions. Local governments threats driving innovation at the federal level :P

> recent pressure to close airports (namely KRHV) with leaded fuel It's always been a real estate issue with KRHV. The nearby busy highways emit vastly more emissions than trainers, likely including lead. What city councils refuse to acknowledge is that once you close a city airport, you can never build another one. This is especially an issue in an earthquake zone.

  What lead is coming from a highway?

    From car paints and tire balance weights.

    “Unleaded” fuel is permitted to contain up to 50mg per gallon*; though this is a limit, none is permitted to be intentionally added. 100LL by comparison contains 550mg per gallon by intent. * Sorry for the crazy mixed units; I didn’t write the regulations.

    There's likely trace elements in fuel. In the case of that area, the Capitol Expressway is a very busy highway system. If RHV air quality is monitored, then so should some locations around the highway. In fact, there's enough cars surrounding the airport that it would influence air quality measurements inside the airport perimeter. I mentioned the quake issue because I have seen documentation that RHV is part of the emergency response plan for transporting relief cargo.

  > What city councils refuse to acknowledge is that once you close a city airport, you can never build another one. Is that a bad thing? A substantial fraction of the population uses the local highway on a daily basis, whereas very very few people use small local airports with any similar frequency

    - I've never used the hospitals near me, but I'm glad they're there - The airport existed before the houses went up - airports can be used for many functions that benefit society, including EMT and business travel - houses aren't the only zoning category, or even the most important. We have industrial, retail and other zones which help society overall.
