1️⃣Weight can be defined as the force of gravity acting on a mass.
2️⃣Weight during free fall is the same as if stationary, gravity hasn't ceased or changed in strength so there's the same force of gravity still acting on your mass, giving you weight and causing the acceleration.
3️⃣It may appear to a free-falling person that they are weightless, but it's artificial.
4️⃣The problem is that conventional forms of weighing will read zero because the equipment will be free-falling too (we have to rely on Newton law 2 .. F =ma)
