Good day collegs. I'am a pilot in command on Da 42. I fly in Ukraine. I
have a problem with progress of flight. These days all lokal aerodromes of
Ukraine coverage with a snow. In many METARs of Ukraine the given
coefficient on Runway is 0.3.Neither In my AFM nor in any revisions,
supplementaries, I couldn't find coefficient of adhesion Da 42. If you may
help me with this problem.

Re: DA42
If the coefficient is the same as the one used in Canada, you don't need any info about the plane to use it other than whether or not the plane has thrust reversers.
Simply look up your required landing distance on a dry and bare runway (from the AFM) in the table and adjust for the coefficient. The table below is for planes without reversers:

For example, based on that table, if your plane normally needs 2000 ft. for its ground roll (per the AFM) and the reported CRFI is 0.3, you would need 4490 ft. of runway to land.
