What's the biggest (most flight-critical, odd, etc.) item you've had MEL'd?

Re: What's the biggest (most flight-critical, odd, etc.) ite

We had something in excess of 10K on the fuel load going from CHS-MEM with no alternate. The thing is a big time pig with the gear down and hot and heavy. We did about 1.0 a min to 12K' then 500fpm to FL180. To hold 250 was about 90% power. But APU outage is horrid... especially when the ramp is backed up and you are cooking in the sun waiting for a NW 9 to finish at their 40% speed...

Not picking on you higney.......but all of you jet/ dash drivers are spoiled! Whaaa, my APU doesn't work. Boo Hoo :tease:

Try hanging out in a SAAB or a 1900 (has no APU) leg after leg, day after day, baking in that thing and sweating your a$$ off. It's nearly impossible to get A/C carts at most stations, they either don't have them available or are just too lazy to get 'em. :mad: :banghead:

I know he was complaining about not having AC on the ground, but keep in mind, we need to the APU to start an engine too. Sure, it's nice to keep the cabin cool (and in the CRJ 200 the APU doesn't do that too well anyways) but I HATE having to wait around for an aircart to crank up an engine.

(and that is the FIRST time I have ever heard somebody call a Dash Driver spoiled!)

Oh, I forgot my strangest MEL: Avionics Rack Cooling Fan in the Saab 340. We showed up to the airplane to find the avionics cover missing, which happened to be a cabin-sized wall that hid all the avionics behind the Captains seat. This wall faced the passengers, so all of our customers had a great view of wires and boxes for the short flight we had. Only had flight instruments, one VOR/DME, and one ADF available, on the Captain's side. Otherwise, everything else avionics-wise was turned off.

That's funny. I was in the Saab the other day and they had to pull that wall down. On the back of it was a sign that said "Do Not Remove from Aircraft" right below was "If found return to...." I was trying to figure out where someone would find it.
 
Re: What's the biggest (most flight-critical, odd, etc.) ite

I learned an awesome tip during my upgrade Oral. Just think about it...what's a constant source of air that isn't dependant on TL position?

Just crank up the APU and put the packs on it below 25K. Then you have a constant, steady stream of air that you don't really have to mess with.

yea, that realization hit us about the time we were lining up for 22L @ ewr.

Yeah, but the biggest pains of having a deferred APU don't have to do with the temperature. Starting with a huffer is often an pain in the a$$ because a lot of the time they're way underpowered.

We also normally take off with the high-pressure air for pressurization supplied by the APU, although it's generally not a problem to take off with the HP air from the engines (there's usually a small takeoff weight penalty). In the CRJ200, though, we can't take off with both the packs on the engine bleeds and the anti-ice on, so in icing conditions with no APU we have to do an unpressurized takeoff. Not a huge pain, but requires a little extra work and a supplemental checklist which isn't necessarily fun when you're taking off out of Reno in a snowstorm.
 
Re: What's the biggest (most flight-critical, odd, etc.) ite

Had a deferred APU going into TUL last month.

"You guys have a huffer cart, right?"
"Yeah. No problem. We'll have it all set when you get here."

After we pull into the gate...

"Uh, they forgot to plug it in last night, so the air isn't ready....we can either hot fuel you or you can shut the engines down and wait 2-3 hours."

Needless to say, I wound up standing out in the rain watching the fueler pump gas with the fire dept 20 feet away from the #2 engine....

We have a captain here (Bahama Bob) who flew a 200 CLT-Georgetown, Bahamas. In route the APU died so when they called ops they asked if they had a ground air cart. They said they did so they shut down both engines. Of course they had a ground AC cart, but no high pressure cart. The plane was stuck there about 5 days while they flew in parts (the wrong parts the first 2 times) and a mechanic to fix to the APU.

Sounds like you guys have a nasty hot refuel procedure. We just need no pax on board and a "trained" person to have eye contact with the cockpit and the fueler. No Crash and Fire needed, although it's not a bad idea.
 
Re: What's the biggest (most flight-critical, odd, etc.) ite

We're not required to have CFR there, but they show up 90% of the time we do it just to be safe. We have the FO standing there with eye contact on the CA and the fueler, but we board passengers at the same time.

Had to almost slap a fueler today b/c he started fueling before we even opened the door. He was a little confused why I was having a "chat" with him on my walkaround.
 
Re: What's the biggest (most flight-critical, odd, etc.) ite

We had a guy (in LEX I think) start to deice the airplane while we were still at the jetway with passengers boarding. It was a 5:25am departure so I wasn't all there yet when he started up the truck and drove over.

Me: He isn't doing what I think he's doing?

CA: Naw... nobody is that dumb

(guy climbs out of the truck and gets into the lift)

Me: He does look pretty dumb.

CA: Not going to do it. He's just getting ready.

(Type II Goo sprays all over the nose of the airplane and splashes in the boarding door)

CA: (As he flashes all the landing lights at the guy) Yep... he's that dumb.

Ok, so there it is. You people need the APU for more than cooling, et al. Guess I'll let you slide then. :o But if you were on our side of things and were listening to the ops freq. when people are calling up about no APU and getting snotty about needing an A/C cart when we're dripping wet w/ sweat on a regular basis in the Saab.......well, it kinda rubs the wrong way.

On a side note, those airstart carts are crazy loud......sounds like a hurricane rolling through. :panic:

(and that is the FIRST time I have ever heard somebody call a Dash Driver spoiled!)

Well, guess there has to be a first for everything! Those dash drivers are spoiled w/ their RNAV too! :sarcasm: Slant Alpha is where all the cool kids hang!



[size=-3]DISCLAMER: this doesn't mean all RNAV/ APU-equiped-plane drivers are snotty or spoiled![/size] :)
 
Re: What's the biggest (most flight-critical, odd, etc.) ite

FYI, main purpose of the APU isn't cooling or even engine starting: it's generating AC power.

Which is required for the avionics cooling fans... no AC, no radios/fms/etc. When I get to an A/C with no APU, the last thing I'm thinking about is sweating in the cockpit:).
 
Re: What's the biggest (most flight-critical, odd, etc.) ite

Trust the Canadians to make an aircraft with a DC powered Avionics Rack and an AC powered fan to cool it. You'd think they were up in the woolly white north or something. Oh... wait...
 
Re: What's the biggest (most flight-critical, odd, etc.) ite

It's not really all that critical but I will cast another vote for the Fuel Quantity Indication/Pressure refueling system MEL on the ERJ being a PITA, especially the first time you do it.

Had that one twice in the past few months. At least after flying a 5 legs in a plane with that MEL, it starts to get easier.
 
Re: What's the biggest (most flight-critical, odd, etc.) ite

I don't want to see any more aviator brothers on here crying cruise. heh heh...jk.

On my first flight off of IOE, we had the autopilot meled on a trip from IAH to PIT...in huge thunderstorms. I turned to my CA and said... "I feel really sorry you, you poor bastard. I'm brand new stupid, there are thunderstorms, and the auto pilot is gone."

It was a great trip though, learned a lot.
 
Re: What's the biggest (most flight-critical, odd, etc.) ite

On the Saab, just about everything imaginable. One of wildest ones was the prop De-ice. Found one of the boots seperating from the blade on preflight. Mx came out and ripped it off along with the boot on the opposing blade.

On the 727, some notable ones were (DE727UPS you'll appreciate these):
Standby ADI
Pack Fan
Fuel Gauges (drip sticks are fun) Yes, I said drip sticks
APU
 
Re: What's the biggest (most flight-critical, odd, etc.) ite

On the Chinook, the Advanced Flight Control System (AFCS). The AFCS works with various components to make the aircraft a lot more stable. Without it, the helicopter becomes a handful while hovering, but even more so in forward flight. As a quick example, you might have to hold a significant amount of aft cyclic to keep the nose pitched down so you have forward airspeed. It has a tendency to get into significant oscillations and keeping it coordinated doesn't follow any normal laws of aerodynamics. At any rate, it's a major PITA!

Got real lucky to have the number 1 and number 2 AFCS die on me on a multiple day mission in Iraq when we were sling-loading 18,000 lb containers all over the place.

A heavy swinging load attached to an inherently unstable helicopter = major suck factor.

And my air-conditioning was inop as well seeing as they failed to install it at the Boeing factory. ;)
