Title: Re: Takeoff Performance
Post by VulcanB2 on Oct 7th, 2010 at 8:11pm
Hi,

Interesting comments.

I found that if I use 107% N1 for takeoff, that she seems to not use as much runway when fully loaded as I was expecting (I figure about 6000 ft).

Once airborne though I found that she climbs OK?

If memory serves (please correct me if I'm wrong!!), it is ~107% N1 for takeoff with an initial reduction to 101% at 500 ft and then climb out to acceleration altitude, where thrust is further reduced to 97% for climb.

FS EPR is broken. Using N1 figures above I get EPRs of 2.10 or higher.

Best regards,
Robin.
