New environmental envelope 2 OLM FBW 2006
Why?
Need for higher flexibility in operations:
for operations over metric areas
Flight Levels 11 400 m / 12 000 m / 12 600 m
for routes with very low temperatures
New environmental envelopes
What ?
Extensions at high altitude and low temperature:
41 100 ft (12 500 m) 41 450 ft (12 633 m)
41 100 ft = 12 500 m

New environmental envelope 7 OLM FBW 2006
Conclusion
Improvement of cruise limitations in specific airspace flown byLong Range aircraft:
Minimum temperature: 78C for very low temperature routes
Maximum altitude: 41 450ft
FL 12 600 m becomes reachable
Available for LR fleet:
-78C is given to all A330/A340 by default
41 450ft is provided on request (SB 00-3049 and 00-4045 -Mod 52536)
