Answer:

1.47 km

Explanation:

When the pilot hangs freely in the seat and does not push against the  seat belt, his centripetal acceleration would counter balance gravitational acceleration g = 9.81m/s2 = a

We can calculate the radius of the loop using velocity v = 120m/s and a

a = \frac{v^2}{r}

r = \frac{v^2}{a} = \frac{120^2}{9.81} = 1467.89 m or 1.46 km
