70 years later, there's a solution?
Welcome to what it was like in "full throttle" Southie back in the day, but even now, there are "heavies" that shake the house while grabbing air, FEDEX and UPS are the biggest culprits, usually about 9:30pm and 1:30am.
Last week, inbound flights were using 33/15 IFR and one blew the approach and did a go-around that was, let's just say, "noticed". For a couple of seconds, I wasn't sure if it was going to drop in for a visit and say HI.
Less air pollution too?
Hope it works.
The article says it'll cost
The article says it'll cost up to 20 gal more fuel/flight, That doesn't sound like a lot.
Wait ...
How does more fuel consumed mean less air pollution, again?
Who said more fuel consumed
Who said more fuel consumed means less air pollution, besides you?
Uh ... Anon?
I worked with the scientific basis and data behind air pollution regulations for nine years, so, um, yeah I qualify as someone who would know something about this.
Let me explain it to you s l o w l y:
more fuel burnt = more emissions because MORE: more stuff in = more stuff out
more fuel burnt = less efficiency in burning because less efficient = less burned stuff = more waste stuff
more emissions = more pollution
less efficiency = more pollution
Those silly laws of thermodynamics get in the way, too. But that's a little too involved for you.
Velocity
I'm not an engineer, but won't they fall out of the sky if they go slower?
Probably has something to do
Probably has something to do with how they angle the plane or its control surfaces. When the plane is moving more slowly, I'm guessing it has to have a higher "angle of attack" (am I recalling this term correctly?) in order to direct more force downwards.
happy dance
