My instructor wouln't let a student solo which couldn't fly a aircraft
without instruments. He covers the instruments, calls out a target
airspeed and the student has to pitch the plane to that speed, give or
take 10 knots. The exercise includes a stall training, too, to know at
which pitch the plane stalls and the feeling of the controls getting mushy.

The training came handy the day I experienced my first ASI failure. As
my destination had only a 1000 ft runway, I decided not to try and land
there without ASI but rather to return. The landing at my home field was
a non-event, as our runway has plenty room for error with its 2000 ft.

Of course, we're not talking jets here.
