The Cargo Door

I noticed this image on the main page of the UPS website. All of their aircraft, as far as I am aware, have their big cargo doors on the left side. However, in the image, the doors are on the right.

It seems like the picture was simply mirrored with a neglect for the technical aspect (which few non-aviation fans would notice) but I have a couple questions. Are there any aircraft in existance with the door on the right side? Also, would there be any benefit to put the door on the other side, or to add a second door?

The lower deck cargo doors are almost always on the left, because that's where they are on the passenger models (which almost always predate the freighter versions). That keeps the cargo loaders away from the jetways.

Upper deck cargo doors can go on either side...on a dedicated freighter, you don't worry about a jetway (or all the other support trucks) so you might get better efficiency by avoiding a conflict with the lower lobe cargo door.

Or...they just reversed the photo. For this particular plane, I don't know.

This picture is back to front.


This a B757, and you can see the belt loader going up to the lower fwd cargo bay is on the wrong side.
I have never seen a freighter with the main deck door on the right.

err., Left is usually the left looking from the back, so the lower lobe doors are all on the right
Except the bulk cargo on B767 (and B787?) which are on the left.

Just a thought...

I think this photo was reversed for one main reason, so that you can balance the photo correctly without having the wording on the right side of the picture, if this is an ad, then it would be more desirable to have the lettering match up with the left side of the picture than the right because we read left to right that is where your eye goes, then onto the aircraft. I only say that it was reversed because I have never seen a belt loader on that side.

But I might be completely off...

The only lower deck cargo door I have ever seen on the left hand side of the fuselage is the aft cargo door on the DC-10.

I went briefly dyslexic there...I was thinking left in the photo, which would be right on the aircraft.

As a sidenote, AA once required that the passenger door be on the right side, which is why their DC-3s have a right hand door. Not sure if any other DC-3 customers ordered the right hand door.

As launch customer for the Convair 240 to replace their DC-3s, AA maintained the right hand door requirement. I believe all Convair 240s had the right hand door. It moved to the more usual left side on the 340 and 440. I think the 240 was probably the last airliner built in any numbers with a right hand passenger door.

A right hand door was also a feature of the Curtiss Condor biplane, operated by AA as a sleeper aircraft with upper and lower berths on night flights in the mid-1930s. They were replaced by the DC-3.

Most art directors flop images to accomodate layout and copy gallies and have no idea that it is incorrect...I had a client run (print) 10,000 brochure covers of a challerner jet stock photo he got...after I saw this, I noted to him it was incorrect...he then tried to mask the "f"up. Two weeks went buy he was fired and I was asked to shoot an air to air of clients new challenger. I have seen this many orther times...j

Patriotic maybe  Wink since Fokker was a Dutch company.
I believe only a hand-full Fokker 60's have been built. In general the Fokker 60 is a 'stretched' Fokker 50. The reason for having the main deck cargo door on the right hand sinde is unknown to me. I have no idea of the refueling point location.

Mel,

The refueling panel is located just in front of the RH MLG.....it's a panel on the bottom side of the nacelle and hinges downwards to inboard.
The refuelingadapter is located below the RH wing just outboard of the nacelle ( approx 3ft ).

The reason for the cargodoor on the RH side is the paxdoor on the LH side. As you can see the RH fwd emergency door is located in the cargodoor and the main entry door is located on the same position on the LH side.
If they'd installed the cargodoor on the LH side then they had to change the LH and RH side of the fuselage and in this case only the RH side.

I've been working on the KLC Fokker 50 for 11 years so I know my way around these puppies  Big grin

Regards, Arjan

I found a picture of a F50 being refueled http://www.avianet.nl/redactioneel/2008/2008-01/red3247.htm ....scroll all the way down.
This image also shows the fueling control panel which hinges outboard instead of inboard...my bad  banghead

I head through SDF fairly regularly jumpseating home. As of this time I have never seen a UPS 757 or any of their other aircraft with the main deck cargo door on the right. I know a 757 captain there I'll have to ask him for sure next time I see him.

The US Navy got some of their GIV's with a right hand cargo door.

The reason however is somewhat obvious, the aircraft retain their left side airstair.

Interestingly except for the -PF.[LH System]...most B752 freighters have a seperate & isolated Hyd system for MDCD operation.Adds to the reliability.
