Having trouble understanding how a plane is able to fly if the thrust it generates is less than its weight.

If you’ve taken physics A this how it would likely be explained. In physics you learn that vectors are not communicable in different dimensions this means that a vector that’s acting horizontal has no idea what the vector acting vertical is doing.

Thrust acts horizontal, all thrust needs to do is counter the drag force vector which also acts horizontal but against thrust. If the thrust can do this, the plane can accelerate, thus gaining velocity.

A plane flies do to the lift force vector which acts vertical countering the gravity force vector also acting vertical but downwards. Lift is a function of airspeed meaning, the more speed, the more lift (essentially) so all the thrust has to do is gain enough acceleration so that the lift force takes the aircraft into the air.
