Chit Chat Thread For The Week Of June 19, 2017

Happy Monday, everyone. More trips around Wisconsin for me this week.

And a good good Monday to all

Be safe.

Have a nice week everyone

blah blah blah

Checking in.

After some cool and rainy weather, it is beautiful today. Going to take the RZR out tomorrow.

Please be safe out there.

Nice weather here, have a great week.

hello

But, oh well.

Have a safe week!

Have a great week, all!

Scorcher here the last couple of days. Have a great week everyone.

Have a great week everyone!

Hi All

Finally getting the rain we need so desperately.

Yesterday was okay, until the heavy rain started while I was still outside. Today however looks okay.

Enjoy the day.

Rain on and off all week.

Picked up over an inch rain yesterday as the storms accompanying a cold front rolled through. We can use the rain. Maybe not delivered all at once though.

We have hot humid weather.. take care!

Fires are active in a big area in central Portugal. Update , since Saturday 63 dead, 155 injured. Portugal is receiving help from all over Europe to fight these fires. Temperatures are on the 40 degrees Celsius. There are emergency members from various part of with airplanes fighting the fires where it is possible.26.000 hectares burned.

I'm in the middle of a major renovation of the summer cottage. Too much fun!

Have a great week.

Heading for 120 today here in Phoenix AZ Metro. Some airlines have already cancelled flights due to the reduced lift and poor engine performance.

All-time recorded high is 122, so we're getting close.

Nice weather here in MD today, a nice reprieve from the heat wave we had recently.

Hadn't thought about the reduced performance of jet engines. They compress the air but rely on thermal expansion of the gas for powering the fans. It wouldn't solve the reduced lift problem but you could mist (distilled/deionized) water into the intake on takeoff to reduce the air temperature and improve engine performance, especially since the humidity is generally so low out there ("it's a dry heat!").

I guess the reduced lift makes takeoff and landing dicey though so perhaps cancelling the flight is the smartest option...

A great week to all, and to all a great week!

Official beginning of summer is 11:24 PM today. Very nice mild day today, but after last week with upper 90's and high humidity, I feel like we have already been through summer!

Another week? Wow.

Enjoy your week

AC went out last night, repairman came out this afternoon and topped off the Freon and said I was all set. Last a couple of hours and now cycles between no AC and some AC. Guess it is another call in the morning.

Enjoy the week!

I think summer has arrived here in the Silicon Valley, scorching hot during the weekend and will be for the the next couple of days.

Have a Great Week.

New season of Wrecked started tonight.

Yea, finally my husband and I get our quite, clean house to oursefve again... been six months.

Running out of things to say.

We've had some weird weather the past couple of weeks. A tornado touched down northwest of here ten days ago (perhaps you saw the video of the guy mowing his lawn?), and another "possible" tornado occurred last night.

Although we get the occasional (weak) tornado, Central Alberta is not Tornado Alley. Weird!

Good morning.

Have a good week everyone

Have a great week, everyone.

to all.

... and I get to leave the Democratic People's Republic of Kaliforniastan! (DPRK for the uninformed).

Anyone who has drag-raced knows what heat, barometric pressure, and to a lesser degree, humidity does to engine performance (especially unblown engines). This is because the air's Density Altitude becomes much higher relative to standard conditions. This makes the air's density equal to what it is at that altitude under standard conditions.

If you don't believe this will also affect aircraft lift, here's an example of 'proof is in the pudding'. In 1989 a pilot took off from Cedar Rapids, IA, in a 4-seat aircraft on the way to Colorado Springs, CO. When he prepared to return to CR, he loaded the aircraft with the same passengers and cargo he left IA with. He didn't make it. Guess why! They listed 'inexperience in high altitude flying' as one reason for, "According to the report, the plane didn't climb high enough after takeoff to clear a utility pole a half-mile from the end of the runway".

There are several online Density Altitude Calculators available. Plug in 75 Degrees, check the Density Altitude. Then plug in 120 degrees, and check the Density Altitude. Huge difference.

hi

Hi right back at you...

I'ts been triple digits for the last three days in SOCAL. Supposed to cool off to the high 90's by the weekend

We're being bombarded by rains recently. Stay safe veryone.
