Re: Wisconsin Aviation Thread - 2019

I noticed delta is sending 757s DTW-MSN since the beginning of the month. It arrives at night (DAL 2080), and leaves in the morning (DAL 2091). Pretty impressive, in my opinion, for MSN. Also seems like an odd route for a 757, being so short, but I assume Delta really needs the morning capacity out ...

Currently a JAL 777 sitting by terminal 2. Not sure when it arrived or when it departs. I assume it is a baseball charter.

Re: Color Blind - Class I medical

No restrictions for daytime flying though. Light gun signals are used in the daylight, too. Colorblind people CAN see colors - it is just harder to make distinctions between CERTAIN shades of colors, most often certain shades of red and green. Most people with colorblindness don’t even know they ar...

Re: Color Blind - Class I medical

Yes, you can get a medical with a restriction that reads “NOT VALID BY NIGHTFLYING OR COLOR SIGNAL CONTROL”. However, lots of places won’t hire a commercial pilot who is unable to fly at night. The color signal control limitation is quite meaningless because color signal control is generally only ne...

Re: America flight 1200 heading back to PHX.

This thread is amongst the most cringeworthy I’ve seen on this website.

All posts should be deleted except post #7, which is the only post that is not cringeworthy, off topic, or completely inaccurate.

I believe the 787-9, unlike the 787-8, has an HLFC system on the leading edge of the v-stab.

Re: BA27 A380 having problems currently.

I like that idea. Very smart. Excellent observation. I believe I read somewhere that fuel dumping from altitude rarely resulted in anything actually hitting the ground. Whether that was the case from a relatively low 10,000 ft altitude I couldn't say. That just leaves whether it was better to dump ...

It’s safer to have airspeed (rather than straight up/down) so the pilot can autorotate in case of engine failure at lower altitudes. So I would assume that it is for risk mitigation.

Re: Future engine improvements

FWIW, one area efficiency will improve is with material science for high temperatures which currently limits the temperature in the burner. A higher delta-T in the burner is more efficient, but current material limitations don’t allow for it currently. https://www.grc.nasa.gov/www/k-12/airplane/burn...

Re: 737MAX vs 737NG Stability

See static vs dynamic stability. I would assume it is the dynamic stability that is “in question” rather than the static stability. Aircraft can have negative dynamic stability if a computer can account for it. Modern fighter jets for instance are inherently designed this way because it results in i...

Probably just radar vectors from the STAR (HAARP3: http://155.178.201.160/d-tpp/1804/00289HAARP.PDF) to a visual approach. 2800 ft is the minimum vectoring altitude directly over the part of the city with tall buildings. https://www.faa.gov/air_traffic/flight_info/aeronav/digital_products/mva_mia/pd...

Do either of these have any chance? I think #1 is better, but I thought #2 is an interesting angle.

Do these night shots have any hope

I tried night photography at KMSN with my new 80D and old 70-200 f/2.8 IS. I've been inspired by Keiichi's photos. I am nowhere near as good as him, but do these have any hope? I think I overexposed and probably could have used a lower ISO as I ended up adjusting the exposure down about a full stop ...
