It has weight-- but not lift. It also has no thrust nor drag. It needs forward movement/trust, velocity, and lift to get off the ground.
When a plane is still on the ground, the main forces acting on it are weight and normal force. Weight is the force due to gravity acting downward, while the normal force is the force exerted by the ground perpendicular to the plane to support its weight. Additionally, there may be frictional forces acting on the wheels to prevent the plane from moving.
When sitting still watching TV, the main forces acting on you are the force of gravity pulling you downward and the normal force exerted by the chair supporting you upward. These forces are balanced, resulting in a net force of zero, causing you to remain at rest.

When an airplane is still on the ground, the main forces acting on it are the gravitational force acting downwards and the normal force exerted by the ground acting upwards to support the weight of the airplane. There are typically no aerodynamic forces acting on the airplane until it starts moving.
There are several forces acting on a still car: gravity pulling it downward, normal force pushing it upward, and frictional forces opposing motion on the ground.

When an airplane is motionless on the tarmac, discounting any winds, there are two primary forces acting on it. First is the force of gravity pushing downwards, and secondly, there is the reactionary force pushing back upwards.
The chair in pushing you up and the gravity pushing you down

It doesn't. Gravity still acts on the plane. Simply, there are other forces involved. For comparison, if you stand on the floor, there are also other forces involved, that don't let you continue falling towards the Earth's center.
Sitting Still was created in 1981.
The Wick Airport at Wick in Caithness, Scotland
He didn't, all he invented was a paving composed of tar and gravel that was given the name tarmacadam, later shortened to tarmac. Now known as asphalt on US roads, it is still called tarmac on airports everywhere.
It is still sitting!
