Would you consider not having GPWS a safety of flight issue while going into RNO or any airport in CO? What about not having TCAS while going into SAN or any other socal airport with VFR traffic scattered everywhere. I've had multiple RAs there without ever seeing the aircraft and I was looking.

OK for those confused.
1. The captain writes up, APU INOP.
2. Captain (if it is flight crew placard able) flight crew placards it as MEL whatever, MOC control number. When the plane came into a MX base, MX would come out and place a permanent MEL in the MX side of the MX log book the MX corrective action block.
3. Now the Captain regarding the item will be required to flight crew placard and do the MX corrective action and be responsible that all previous MEL's are appropriate (which is what MX used to do) and MX will not come to see the MX issue until the MEL runs out.
Terminology may be different from one airline to the next. Every company I worked for the left side of the MX Log Book was filled in by Captain and MX but only MX will fill out the right side of the MX Log Book. Now we are doing MX administrative work which has additional legalities via the FAR's.
But never fear, the ALPA MEC is hard at work giving the store away.

If you write up the GPWS then it will probably say you cannot fly into mountainous terrain or to contact dispatch and maintenance for alternate procedures. They're procedure should be not to operate in mountainous terrain but if it isn't and you're flying into RNO then you could argue it's unsafe and you're not going. But DEN? Come on, that might as well be in Kansas.
If your TCAS is out, per the EMB-145 MEL, you have 2 but only need 1. That means if you have 0, then you're not flying.
If both of windshield wipers are out, guess what, you don't get to takeoff or land if rain is within 5nm. If just 1, you're good to go. Even if the wiper gets parked halfway in your view you get to go as long as the blades can be positioned providing an acceptable field of vision to flight crew. That's in the MEL book.
Same with anti-ice inop. You can fly. Just can't go into conditions that has known or forecast ice conditions. Done that MEL in the 88.

Wait a minute... you figured out what we're discussing because its been rather confusing.
I think I get it now, AE has an odd MEL procedure that includes a Jurassic procedure that a mechanic comes out for every MEL... $$$$$... now if a regional wants to do that on every flight more power to them.

Wow, so the alternate procedures Eagle created to meet the FAA requirement without EGPWS is to just stay on track? I guess that works. Not great. I think at night or in bad weather that may not be an airplane to take and I know that means fighting with the company and that just puts a mark on you and blah blah.
As to TCAS, what does it show under 34-43-00 TCAS II as well as under 1)? How many do you have, 2? Or 1?
Now back to the OP's question does Eagle require a mechanic to come out to the aircraft and verify or complete an MEL?

It's not a Jurassic procedure and we are not the only ones doing it. I was just on an Alaska Jumpseat and had the APU fail on start up. They called the mechanic out to MEL it. While the mechanic was MELing it, the captain was on the ACARS getting a new release to include add fuel for the MEL (need to do cross bleed start) and the FO was keeping the passengers up to speed on the situation.
I've refused aircraft on a number of occasions b/c of MELs and conditions we were operating into.
If we're at a mx station, we'll always call the mechanics regardless if it's legal to be flight crew placarded. You may have been mistaken. Mx has to be coordinated with for any deferral...
We cannot do any action that requires reference to a maintenance manual.

The only reason I said that was because you said this:

Now you're at an outstation. The APU is INOP. You write it up, call maintenance, MEL it and go fly. If you're next destination is a maintenance hub and they're not planning on fixing it then they won't come out to see the book. The next crew will take it somewhere else and the APU may be inop for as long as the MEL allows, nobody needs to see that MEL.
