Environmental Envelope

Used to the Boeing envelope of ISA+39.4°C, can you tell me what limit other manufacturers use?

Thanks

May not be pertinent to your investigation, but why not.

Beechcraft 1900D: -40C to ISA +37C.

Clarence Oveur,

Thanks for the link, but the internet censor wont allow me to open it, could you please tell the temperature limit at sea level.

Cheers

ISA +40°C/-56°C. But since I am reading off a paper copy, it could very well be +39.4°C as well.

The limits are for -1000'/14000' which are also the take-off and landing limits.
