Without a doubt - the APU.
Without that you have to use ground power at the gate and, unless you are in LAS or PHX you will not have any airflow in the cabin. Then you will have to use a huffer to start one engine at the gate, and do a crossbleed start for the other engine.
I'd rather lose an engine than an APU.
Happiness is not seeing another trite Ste. Maarten photo all week long.

I have placarded just about everything that's covered by the MEL's for our fleet types and the one item that all flight crews hate to have on placard is an air conditioning pack. This requires them to file a new flight plan cause they gotta fly at a much lower alt., get more gas and a host of other stuff. I've taken away APU's, autothrottles, autopiolts, F/C lavs, fuel pumps, captian seat adjustments and everything else that can break on the aircraft, but the aircondition pack is always the one item that gets the crews to roll thier eyes and mumble a curse or two.

I agree that an inop APU is a real pain the ass BUT in the MD-11 an inop fuel qty. gauge on the synoptic display causes all sorts of headaches especially if it's a long leg to fly. I've copied a PORTION of the MEL requirements for a SD gauge inop here and deleted about 80% just to show the more important items.
MD-11 Minimum Equipment List
A 3 2 (O) (M) One may be inoperative provided:
a) Fuel Quantity Synoptic indications for
the remaining two tanks are operative,
b) All engine Fuel Flow Indications are
c) All engine Fuel Used Indications are
d) Affected tank is fueled to a known
e) Fuel Quantity in affected tank is
checked by Fuel Level Sticks after each
f) The flight does not require fuel dumping
for the enroute engine out driftdown
g) All Fuel Pumps and (Main) Fill Valve in
the affected tank are operative,
h) Fuel System Controller is operated in
the Manual Mode,
ik) When aircraft’s intended track takes it
farther than 120 minutes from a suitable
airport and trip reserve fuel is less than
23,000 lbs., add a maximum of 5,300
lbs. of fuel or until reserve fuel equals
l) Number 2 Main Tank Fuel Transfer Float
Switch (40K) is operative,
m) Tip Tank Gravity Transfer System for
affected tank is operative,
n) Tip Tank Full Float Switch for affected
tank is operative,
q) If MTOGW is 630,500 lbs and Aux Tank
quantity exceeds 9,000 lbs, comply with
ground fuel schedule of 100 lbs. Tail
Tank fuel per 750 lbs. Aux Tank Fuel.
1. Tail Fuel Management is inoperative.
2. Associated Overhead Panel Indication may be inoperative.
NOTE:If the associated Overhead Display is rendered blank by this MEL, it is NOT necessary to
document relief for the Overhead Display.
3. “FUEL QTY FAULT” Alert may display.
4. If Tank 2 Fuel Quantity is inoperative, the "TNK 2 FUEL QTY LO" Alert is inhibited.
5. Gross Weight, Aircraft CG, and Total Fuel On Board will not display.
6. FMS Fuel Dump to Gross Weight function will not be available.
7. In the event of a fuel dump, fuel quantity as indicated on the FMS will be in error by the amount of fuel
dumped. Recalculate Usable Fuel On Board (UFOB) and enter into FMS Weight INIT Page for accurate
8. Fuel Dump Low Level Cutoff is still available.
9. The FMS may limit aircraft speed to approximately 320 kts.
NOTE:DO NOT use this speed for dispatch and flight planning calculations.
2. DO NOT conduct operations above 78° N Latitude.
3. Operate FSC in MANUAL.
CAUTION:On Preflight, verify all FSF calculations using the FSF Verification Module of the
8. Periodically check fuel quantity in affected tank by subtracting fuel used and quantities in other tanks
from initial fuel quantity on board.
9. Fuel burn is increased by 2.7%.
Years ago, one of our founding 737 captains turned 60 and retired. He spent a couple of years in the local ops, and then became a dispatcher. The guy ("H. T.") had thousands of hours of time, and flew PBYs in the Pacific during WWII. HT was gruff, and his language could be salty and profane when provoked.
Early one morning one of our other captains appeared at the briefing counter to pick up his release for his first two legs of the day, DAL-SAT-DAL, and he noticed that his autopilot (737-200) was inop per MEL 22-1. The captain then proceeded to gripe about it, and apparently took it a little too far for HT's liking, whereupon HT loudly told the griping captain (in front of still other captains) that "I flew 8,000 hours all over the F***** Pacific Ocean getting shot at without a G** D***** autopilot and you can't even make it to F****** San Antonio and back!"
The office went silent, the griping captain quietly signed his dispatch release, left the copy and the pen on the counter, and slowly turned and went out the door, never to gripe again in front of HT...
HT stayed a few more years, and then retired, only to pass away about a year later (cancer). We remember this story (and many others) with great fondness; he was quite a character....

I heard one story where a DC10 arrived at a station and the crew wrote up that the A/P's were inop and they had had to 'pole' it most of the way across the Atlantic. Maintenance went up to check it out & found the lateral control wheel was out of its detent. Put it back in its correct posn and the A/p worked just fine!
