Anne,
What's interesting is that with NVG's you can see through smoke too. A couple of years ago we had a big fire in the mountains that burned over 100 homes. One of the night crews went up there to look at the damage since all of the fire fighting airplanes were done for the day. As they flew along with the NVG's they could see everything really well until the pilot flipped his off and realized they were in total IMC smoke and couldn't see a thing.

Fascinating. Were they worried about the effect of smoke on engine performance?

There was a report on the national news tonight about the very poor air quality in the LA basin. A fire north of La Canada? Hot and stagnant air. Comments?

Anne,
I don't think that was too much of a concern with the A Star B3's. However, if it was a volcano that was spewing ash into the air it might have been a problem.<g>

It's been burning for a couple of days now and without the winds it should be no big deal to knock down. That just makes it miserable for the residents who have to breathe it without the winds blowing it out of here.

Cough...<g>

BTW, next time you make it out this way for a visit to Rancho Cucamonga give me a heads up and we can get you in one of the patrol B3's for a LE ride along flight. You might enjoy that.

Why would smoke effect engine performance?

Oh, I was thinking it might be similar to ash from volcanoes. Or loss of lift is more like it. Could have expressed myself better.

Wouldn't the oxygen levels be lower?

Heat, density altitude. Oh heck, forget I even said anything.

Looking over the Part 61 changes, I see the following change to the private pilot solo XC requirements.

Old language:

61.109 Aeronautical Experience:

(a)(5)(ii)
One solo cross-country flight of at least 150 nautical miles total distance, with full-stop landings at a minimum of three points, and one segment of the flight consisting of a straight-line distance of at least 50 nautical miles between the takeoff and landing locations; and


New language:

61.109 Aeronautical Experience:

(a)(5)(ii)
One solo cross country flight of 150 nautical miles total distance, with full-stop landings at three points, and one segment of the flight consisting of a straight-line distance of more than 50 nautical miles between the takeoff and landing locations; and

======

Did their word processor search and replace mess up? It seems they wanted to replace the language "at least" in the second clause with "more than,' but they also removed the "at least" from the first part of the sentence, implying that the trip needs to be 150 nautical miles, and not "at least" 150 nautical miles.

Thoughts?

John -- Thoughts? I have none. <G>

Typo that they'll have to fix, I think.
