ERJ-135 single engine performance
I am interested to figure out if the ERJ-135 can perform ETOPS ?
I suspect not as it lacks an APU and my understanding is that ETOPS requires continuous APU operation...
So assuming that the answer is no, could anybody tell me please how the ERJ-135 complies with the 90 minute rule ?
From close to it's service ceiling what sort of single engine radius has the ERJ-135 got within 90 minutes of flight time ?
