(4) Rate-of-Descent Switch
It may at times be desirable to control a balloon merely qya
switch activated at any given rate of descent. This could be
accomplished merely by "reversing" the rate-of-ascent switch.
This type of control would prove to be quite difficult, however,
for a constant level flight. One flight, No. 97, was made
using a type of rate-of-descent switch ·&s shown in Figure 16. In
