Title: [ok] B720 new runway distance
Post by: groundbum2 on June 30, 2019, 09:43:12 AM
I've just looked at the new (since fuel consumption update etc) B720 in GW1 and runway has gone up to 3350, further than the 707-120 at 3150 even though the 720 is billed is built for shorter runways...It was a lot lower before this update. The 707-120 went from 2250 to 3150!

Checking the charts from manufacturer:

* B720 MTOW 104000, JT3C-7 engine, standard day, sea level => 2800m
* B720B MTOW 106200, JT3D-1 engine, standard day, sea level => 2000m

Probably looked at +15 ISA temp charts accidentially since that is about 3300m.

Checked other 707 variants and they are ok.
