Hello!
Indeed I'v received Tech Request by Airbus.In spite of reference from FCOM (downgrade 2 for T.O) the Airbus recommend to extract RWY condition from RCAM.But they mentioned about not standard RCR issued by Helsinki apt. They said essential method to take RWY condition for T.O. calculation, but in according with example the proper way to step down RWYCC 2, and take according condition.
In any case I agree with opinion about the T.O. method calculation is not exact versus LDG performance calculation.
Moreover if apt. does't have Digital ATIS, it's difficult to receive actual RWY information, the METAR not included any RCR.
Please if you have some thoughts share with us.
Thk. everyone
