Quoting kcrwflyer (Reply 48): Can you explain to me how an e-jet is louder than an Airbus or Boeing narrowbody? |
This is well known at noise sensitive airports that are required to monitor. Its not much better than an MD-88.
Takeoff noise is even with an A320 with a V2500, approach is even with a 737 and flyover is 12-15db higher than both the 320 and 737. Cumulative is 2db higher than both. The problem is its underpowered. Once up, the A320 and 737 climb faster so the net impact is less. The GTF will no doubt fix this, but for now its ugly.
Quoting kcrwflyer (Reply 48): I didn't think the E-jets had any climb problems since they have leading edge devices and they use them in places like EYW, LCY, etc.. |
This doesn't make them quieter. You're also looking at runway performance, not the climb (beyond about 1/4 mile) which is where the noise becomes an issue.
