[BUG] - ECON climb speeds too low #1809

Open fugotaro opened 21 hours ago

fugotaro commented 21 hours ago

Describe the bug

ECON climb speeds too low

Steps to reproduce

Fly with ECON climb speeds

Expected behaviour

Climb at considerably higher speeds

Most opperators didn't use an ECON climb profile instead they used the ECON cruise speed for the mach climb speed and the IAS climb speeds at or around FL250 of the transitions from IAS to mach which was mostly around 350 knots.
