Q

In a steep turn, Load Factor is MORE or LESS than straight and level flight

A

MORE
Lift > Weight

Forces no longer equal as lift acts perpendicular to aerofoil. Weight continues to act straight down, but lift now acting with a horizontal component.
More lift required to counteract the loss of lift. Done by increasing AoA in turn
This creates centrifugal opposite reaction. The resultant force of centrifugal force and weight is G Load
