ATR 42/72 - Why Is The Cargo Bin In Front?

Sun Jul 09, 2006 1:35 pm

My question is a pretty simple one - Is there any specific reason ATR put the cargo hold in front on the 42/72?

Maybe this option provided the best utilisation of space - toilet at the back where it's narrow, and cargo up the front where it's wide etc. This could also reduce aft-heavy situations during loading of cargo.

Everytime I've seen an ATR it has a tail stand thing attatched to it...

ATR already had cargo versions in mind when they originally designed the ATR-42/72. Saves on having to cut out and install a forward cargo door (Although with new-built ATR Freighters, they have a larger forward cargo door, and the older ATRs can be coverted to the Full Freighter standard with the larger door so they can accomodate standard ULD containers). Some operators use their ATRs in a quick change variant, and fly passengers during the day and cargo at night. FedEx's ATR-42 Freighters retain the original cargo door:

Other similar configured planes that had that feature were the Convairs and the F-27s.

I assumed that it had to do with restraint of cargo rules favoring placing it forward of all the passenger seats. Combis are usually set up this way.

Quoting N353SK (Thread starter):

Because the aft area is taken up with the aft cargo compartment. It's just the way ATR designed it.

The 747M/E and MD-11C must be nightmares to load.
Exceptions confirm the rule.

Probably more to do with weight and balance to keep the plane from resting on its tail when on the ground by keeping the heavier cargo up front. I think the cargo restraint rules would be the same considering there are crew in front of the cargo too.

Wouldn't the Avoidance of Cargo crashing into the Pax on Deceleration be the Primary Issue if the Cargo was loaded Aft.

I'm not sure what you are getting at. Of course cargo coming through the 9G wall into pax would be the concern since they would be fwd of the wall. Cargo coming through any wall is a problem. I think the avoidance of cargo crashing into the crew would be the primary issue since they are the ones in control of the airplane.

But, again, I think the primary reason why combis are loaded from the front is for weight and balance to keep the airplane from falling on its tail.

I didn't know that. So there's a forward compartment and an aft compartment?

F.27/227's had main deck baggage up front, Convairs had baggage underfloor, with pax airplanes.

Not quite the same.

How do the pilots get into the flight deck? Do they enter through the cargo hold?

IIRC they have their own door and also access through the hold. Can't remember exactly.

On ASA's ATRs there is an aisle that runs from the flight deck through the middle of the fwd cargo hold to the pax cabin. Pilot and F/A access is from the cabin.

Right. A cargo net divides the fwd cargo hold into two halves, one on each side of the aisle. This allows the cockpit crew access to the deck through the cabin and the cargo hold.

Here's a close-up of a forward cargo door on an ATR-42.
