Help with ERJ questions

[b8tme]

What is the difference between the ER / LR / XR in referance to the ERJ. What is A1E. What does ISIS stand for?v Also, What is Dry Motoring? And finally, What is a hung start? Thanks for any input.

Er (Extended range?)is the first model produced. Slighly more airworthy than a toaster.

LR Long Range. On a constant mission to prove that Bernolli was wrong.

XR. Extra Range(?) Not a bad airplane considering it's made in a 3rd world country by the lowest bidder. Good speed/climb can carry all the weight it needs to. With the winglets it has something like 4 extra feet of wing on each side. Which is the problem with the ER/LR. Big airplane.....no wing

ISIS, Intergrated StandBy Instrumentation System....Proof that you really should not temp fate!

Dry Motoring is when you turn the engine yet do not introduce fuel.

And a hung start is when the engine does not start due to a lack of compression/ignition. But better a hung start than one where it trys to start for too long and then lights off attracting the attention of airport fire rescue.

Thanks,
I thought that is what ER, LR and XR stood for, but really what is the difference. Any idea what A1E stands for?

b8tme-

It's an Allison/Rolls Royce 3007AE with many fadec varieties, A1, A3 etc.

BLASTFEAMER!!!!!!! Actually I've got less than 1K in that POS. Most of its in ATRs.

The engines are as stated above just the A1E is on the 145XR.
The A1/p is the LR and A1 on the ER. And lets not forget the A1/3 on the 135. ALl the same engine except the for thrust output. ER doesn't have enough. The LR has some and the XR has more than enough but no one knows how to get it The XR has so many thrust modes I just call it reduced, full and "super secret"

A1E refers to the model of AE3007 engine it is.

If I remember correctly the A's are the classics (only seen in museums and early Citation 10's) then they went to the A1's , then A1E's, then A1P's. Each one is essentially a slight improvement over the other. Since Rolls bought out Allison the engine has been greatly improved, especially over the piece o'craps that our original ER's came with. We were getting about 500 hours out of each engine (assuming they didn't overtemp/compressor stall/ITT harness failure/etc) before returning them to Allison!

the difference in er/lr/xr is range....

the er/lr are pretty much the same as far as airframe (more fuel etc) but the xr is a little different...

It has winglets and better internal seats for the "four hour tour" to the westcoast...the cockpit is pretty much the same from what I have been told...the xr has a range of 1600 nm ....

Aircraft : Commercial Aviation : ERJ 145Location



quote from the embraer website:

A pressurized jet for regional transport, the ERJ 145 is characterized by its high performance and low operating costs. Available in Extended Range (ER), Long Range (LR) and Extra Long Range (XR) versions, the ERJ 145 is equipped with quiet, fuel-efficient turbofan engines. The cabin of the ERJ 145 has a maximum pressure differential of 7.8 psi, offering passengers the comfort of a smooth, relaxed flight above bad weather. Since first delivery in December of 1996, more than 700 of these successful Embraer jet aircraft have been delivered to airlines around the world.

And then there is the
MP:

Minimum
Performance!

Think of it as an LR with like 9400# fuel and 135 wheels/brakes which means they get hot quickly!

Dont forget about the difference in weight also. The ER tops out at a massive 45,414 while the XR tops out at 53,131. The ER's should be made to perform water landing/float survivability testing.
