Each pilot of an aircraft approaching to land on a runway served by a visual approach slope indicator (VASI) shall
A) maintain a 3 glide to the runway.
B) maintain an altitude at or above the glide slope.
C) stay high until the runway can be reached in a power-off landing.

Afan that can provide air speeds up to 60 m/s is to be used in a low-speed wind tunnel with atmospheric air at 35 c. if one wishes to use the wind tunnel to study flat-plate boundary layer behavior up to reynolds numbes of re 10, what is the minimum plate length that should be used? at what distance from the leading edge would transition occur if the critical reynolds nurnber were rer,e = 5 × 105?
