If an aeroplaneairplane of mass $m$ is flying at a constant speed $v$, the power of the aeroplaneairplane is $$P = m\cdot v\cdot g $$ where $$P = m\cdot v\cdot g \quad \tag{g being the acceleration of gravity}$$$g$ is the acceleration of gravity and therefore: $$F = m\cdot g$$), but, if$$ F = m\cdot g, $$ but, if the velocity is constant, there is no net force as well as no work is done. Then how can the magnitude of power be non-zero?

If velocity is constant, how can p= f*v$p = F\cdot v$ be non zero?

If an aeroplane of mass $m$ is flying at a constant speed $v$, the power of the aeroplane is $P = m*v*g$ ($g$ being the acceleration of gravity$$P = m\cdot v\cdot g \quad \tag{g being the acceleration of gravity}$$ and therefore: $F = m*g$$$F = m\cdot g$$), but,

if If velocity is constant, how can p= f*v be non zero?

If an aeroplane of mass M$m$ is flying at a constant speed of V so$v$, the power of the aeroplane is P = MgV$P = m*v*g$ ('g'$g$ being the acceleration of gravity and thus f = m*gtherefore: $F = m*g$)....but, but,

if the velocity is constant there is no net force as well as no work is done.But But how can the magnitude of power be non zero?

if velocity is constant how can p= f*v be non zero?

If an aeroplane of mass M is flying at a constant speed of V so the power of the aeroplane is P = MgV('g' being the gravity and thus f = m*g)....but if the velocity is constant there is no net force as well as no work done.But how can the magnitude of power be non zero?
