Hey everyone. I've been learning fueling for CRJ 200s and ERJ-135/145s. Today I fueled a CRJ with 10200 lbs of fuel for a flight to TUL and filled a ERJ going to NAS with 6800 lbs. I'm curious what the maximum capacity is for these aircraft in regards to fuel. I was wondering how far I'd have to go before suffering a fuel spill on board these aircraft. I am confident enough with my fuel skills that I'm not concerned with messing up bad enough to consult any manuals but I thought I'd just check on here to see what the experts of A.net knew. Thanks

I can't tell you the numbers, but in general if you fuel to the max in a regional it becomes payload limited. In other words, max take-off weight < max payload+ max fuel + empty weight.

Yeah well I'm not really talking about MTOW or anything of the sort. I'm more or less just asking what is the amount of fuel in these planes that will cause my hose to start overflowing with fuel onto the ground in vast amounts?

Check your company fueling manuals. Those will tell you.

Also, do the proper pre-checks while fueling. Both of those planes (I know the EMB does anyway) will have high level shut off valves.

Thanks KAUSpilot! If anyone has these numbers for a CRJ-200 that'd be appreciated at well.

Not correct. It depends on the model...some have dry center wings, some have wet center wings. The ERJ line all share the same wing, so the -135, -140 and -145 each have the same capacity in each model group. ER aircraft have a dry center wing and the fuel tank ends were the wing meets the fuselage. LR aircraft have a wet center wing and the fuel tank continues under the fuselage.

ER Model- 1373.8 usgal - 11443.7 lbs
LR Model- 1701.4 usgal - 14172.7 lbs

Yeah, I'm sorry, the EMB-135 fuel capacity I listed should be EMB135ER/EP/145ER/EP

The EMB-145 I listed should be EMB135LR/145LR

Thanks for pointing that out EMBQA, but just a heads up, you need to check your conversions there, you have the gallons roughly correct, but you're a few thousand off on the pounds conversion.

So it's

EMB-135ER/EP and EMB-145 ER/EP:

9092 lbs

EMB-135 LR and EMB-145 LR:

11,256 lbs

Those are straight out of the manual. Either way, the original poster should get the point. You're looking at 9000-13,000 lbs of fuel capacity for an ERJ, more if it's a Legacy

That's the first thing I do after I start pumping. Always push the Lamp Illuminator and make sure all three High Level indicators illuminate. One time I had the two high level illuminators light up while the wings were only at 4200 lbs per side. I knew this wasn't right, so the flight crew was alerted. That was a fun day...

Yea, I just used a quick on-line conversion table. The gallon numbers can streight of the EMB-135/145 TCDS so they are correct... but I think total, not usable
