Wind shear

We never did more than 100 knots indicated

That is cool.  Sound like a little hard landing but what do i know.  As for the four lights on the left side of the runway.  I notice that the first one on the rigt turn red and then next and the next as you where over the runway.  I understand that the lights help you on your approched by seeing white but as you are making an approch to land.  When they turns red like that as you right about to land, is that a good approch?

160GS for a Cherokee is really fast. How was the transition to though the wind shear back down?


First when I read your post I'm thinking "what does wind shear have to do with spins?".  :lol

Those are called PAPIs (Precision Approach Path Indicator), they guide you in on a 3° slope. They are made for IFR flight, when your VFR you generally want to descend a bit steeper (however this depends on the aircraft).



What you don't want to see is 4 red.
Given that he was on a Cherokee 3 white is perfectly fine. I haven't really flown the Cherokee much but I think it would even be fine with 4 whites, it does not have the best glide ratio.

Landing was rough - yes I got below the PAPI, when you have a 35 knot headwind it's easy to do. It was my first landing in a Cherokee in a couple months.


I'm just gonna wait until my plane is fixed - I don't much care for the Cherokee

Did they give you a date when they are going to be done?

I understand the shallow final that showed red on the papi would be because you had plenty of runway to work with and that you might encounter shear very low on final that might remove too much of your airspeed margin.

My frame of thinking was that I was high, and that I needed to get down to land, so I took some power out and immediately got below the glideslope

Cherokee flies a little different than the Cessna.

Cylinder #4 needed to be replaced, I needed a new muffler, and the alternator mounting bracket needed replacing. I thought the plane was going to be down for awhile so we decided to continue in the cherokee, but my plane will hopefully be fixed next week. My friend said I could stay as long as I need to with him

Yeah, you should get that spinny thing fixed, kind of important.
