I can't believe all this talk and no one has discussed whether or not the A/C system on props is cool enough to keep it comfortable at the gate and taxiing when it's in the 90's outside.
In the ERJ the packs (off APU bleed at least) do a pretty good job.
I care A LOT more about flight deck temp than whether or not its a TP or TF.

Marketing issues aside (which are not insignificant), dispatch reliability is an issue. However it is possible a brand new turboprop could have higher dispatch reliability than the 20+ year old 50 seat jet it replaces. It might also have RNP capability that allows it to operate in lower weather at non-CAT-II+ airfields than the 1990s avionics in the current 50 seat jets.
Many issues to consider here. In any case, the current 50 seat jets won't last forever. The manufactures insist they only exist because of U.S. airline scope restrictions and don't exist anywhere else on the planet (that seems absurd, but I am not an airline industry economist) but they certainly exist in abundance here and will need to be replaced sometime in the future.
Great point. However this issue has been easily dealt with on business jets with vapor cycle air conditioning systems. Modern variable speed compressors are extremely efficient and not particularly heavy. So this is not an insurmountable engineering problem.

I sure hope so because I NEVER want to ever again experience the pure hell of my previous job with 6 legs a day in SJU in a PC-12 which didn’t do jack to cool anything even at full power. Absolutely worse than flying a 172 in Fla in summer since at least there you can open windows.
The Swiss must think it’s in the 50s everywhere in the world with such a crappy air conditioning system😡😡

Even in the NG at cruise I would roll up the flight plan from the last leg and jam it into the vent to get it actually blowing on me instead of dispersing right away. In the back it was always OK its just that the windshield acted like a greenhouse. The legacies had the advantage of getting started faster which cooled it down faster. I remember too many days in south Florida on an NG sweating my ba!!s off waiting for the screens to boot up so we could start

The E175 was one of the nicest planes I've ever flown...I'm sure they would make an excellent turboprop. The Q400 could have been much nicer if Bombardier didn't make it a common type.
Embraer still can't make a damn coffee maker though.

Actually, it is. Take for instance the Emission Trading Scheme (ETS) that was implemented a year or two ago in the EU. Now, not only do they tax you on the fuel you purchase, but you have to buy carbon offset credits against the emissions of burning the fuel. This applies to all aircraft operators operating to/from and within the EU. This was one of the driving factors behind Brexit. The monies raised by this program do not necessary have to be used in conjunction with any climate program, but may be used on how the government sees fit. By not allowing natural forces to drive the industry (supply & demand, or cost / profit margins), a select group will use taxation and other government programs to dictate business practices.
Now I certainly enjoy clean water to drink and fresh air to breath, I believe in government to protect the citizens against bad business. To that extent, it should be either allowed or not allowed.
To tie this in with the subject at hand, I believe cost/profit margins will encourage Turboprops back into the U.S. industry. But to have the government dictate that they be used for the betterment of society, this is a double edged sword that can be turned against you.
