Re: Is it common practice to use derated takeoffs in snow/icy conditions?

A derate is like installing an engine with different ratings. It’s a selection in the FMS that tells the FADEC to limit thrust to a fixed percentage below the installation’s full rating. 10% and 20% derate being a common option, but as noted could be different, operator option. The modern planes usu...

Re: Is it common practice to use derated takeoffs in snow/icy conditions?

Yes, because by increasing thrust in the OEI case, if the airspeed is below Vmcg or Vmca, the pilot could lose control due to asymmetric thrust. Think of Vmcg and Vmca as redlines below which you must not go in asymmetric conditions and you won’t know where you are in relation to them when increasin...

By reducing thrust thru the derate, the Vmcg and/or Vmca is reduced allowing for lower V1, Vr and V2 speeds. Think of a derate as installing a different engine on the wing with different speeds. Lower speeds means reduced distances or, better yet, greater loads off a fixed distance i.e. a defined ru...

Are you asking about “derate”or “reduced thrust” (assumed temp method)? Two different things. Usually reduced thrust is prohibited on contaminated runways, but a derate might well help things.
