Sorry (again and again)if this topic had been brought forward before, bute surely I've had missed it.

What exactly make a variant an -LR or an -ER? I know that the increase in range is the point, but is it decided by the extra mileage, or percentage-increase of the range, or even other reasons?

One friend of mine brought this question up and left me speechless.

Cheers,

the only LR I am aware of is the 777-200LR.

That is because there is already a 777-200ER.

ER is the first stage. Notice how there is no 777-300LR. Its just -300 and -300ER. If Boeing were to come up with an even longer range variant, it would be the 777-300LR.

The ERJ145 is also available in ER, LR, and XR varients.

It all depends on range. For the 777-200, the base -200 has the shortest range, -200ER more than the base, -200LR the most range. The same goes for the ERJ145. The ER has the shortest range, followed by the LR, topped by the XR.

They are really just marketing tools, with the prefix denoting an improved model.

Boeing used to add 'Advanced' to models to denote improvement, although towards the end of the 727 production run they introduced the 'LR'. Ansett operated four Boeing 727-277LRs.

As for the Embraer 135 / 145......

the EMB-135 / 145ER has a dry center wing box........
the EMB-145 / 145LR has a wet center wing box.......
the EMB-145XR has a wet center wing box and an added fuel tank behind the wing root.

I presume that the A319LR can also carry more fuel than a standard A319?

While this does not apply to non-Boeing aircraft, an -ER suffix denotes a B-market aircraft (6000-8000nm) and an -LR suffix denotes a C-market aircraft with 8000+ nm of range.
