Reverse Thrust How do turboprop jets reverse thrust? It is done through the propeller. “Reversible props” are propellers that can be put into reverse pitch, which acts as a thrust reverser. When landing with reverse propellers, the pitch of the propellers reverse, so that they push air forward instead of backwards, allowing safer and shorter landings on wet and dry runways and reduced taxi time. Beta Range, in a turboprop engine, is the range of power lever positions between flight idle and maxi
