i am rated on E135/E145 and i have about 8000 fhrs.
i have built an app that displays performance of the E135/145 in
TO, CR, LD, EMER.
If you want your preparation look more realistic, you 'll find all the performance needed to accomplish your mission.
No more doubt about RTO distance, EMER Landing distance or even Net level Off!
If you want to play around: erjPerfs on stores.
