Postpatch the 262 seems to underperform at all altitudes and is now incapable of climbing over 7500m, here are some tests done in qmb in level flight to compare actual 262-1a flight data to performance of postpatch 262:

Actual flight data:

sea level 827km/h (514mph)

3000m 852km/h (530mph)

6000m 869km/h (540mph)

8000m 856km/h (532mph)

initial climb rate 1200m (3,937ft)per minute

service ceiling above 12190m (40,000ft)

range 1050km (652miles) at 9000m (29,530ft)



FB 1.1 262-1a:

sea level 800km/h

3000m 730km/h

6000m 600km/h

800m N/A 350km/h at 7300m-7500m



In real life speed rises until 6000m after which drops off slowly, in FB 1.1 speed decreases with altitude until 7500m afterwhich is incapable of climbing any further 5000m short of service ceiling.


plz could someone do a test to compare with results i got in qmb against actual data and also climbrate...
