It was possible to fly on one engine in real life in the Me-110 and maintain altitude.

Twin engine aircraft all have additional speeds Single Engine do not.

Vmc = minimum control speed with one engine out <changes with conditions but is given one a standard day in a standard configuration>

Critical engine windmilling

Most aft CG

Most favorable configuration

Bank angle

Density altitude

All of these effect Vmc.

Vxse = Maximum angle of climb single engine

Vyse = Maximum rate of climb single engine

Both are the same speed as normal Vx and Vy, the rate is ~75% less on average though.

Vsse = intentional engine out operating speed - The lowest speed you can be to practice engine out procedures. This is a safety speed given by the manufacturer.

Twin engine aircraft have their single engine service ceiling and absolute ceiling greatly reduced. It is a function of the density altitude.

Service ceiling is the altitude the aircraft can only climb at a 50 fpm rate. Absolute ceiling is the point were Vx and Vy converge and the aircraft cannot climb at all but can only maintain altitude.

On a hot day and high altitude airport, the absolute ceiling may be lower than the ground level. Our airplane could not maintain altitude and would descend to the ground.
