One method of boundary layer control is accomplished by injecting
A high speed jet of air into the boundary layer.
The lift coefficient must be maximum at
The airplane’s stall speed
%N1
96.7% N1
Leading edge high lift devices are
More effective than trailing edge devices on swept wings
High density altitude conditions result in
Higher true airspeeds
When climbing above the tropopause, the specific fuel consumption of a turbo jet will
Begin to increase much above the tropopause
The Mach number which produces a sharp change in the drag coefficient is termed the
Force divergence Mach number
The increase in specific range with altitude of the turbo jet airplane can be attributed to three factors. One of those is
Increase in proportion of velocity versus thrust required
Trim and stability changes in cruise might be
Drag divergence effects
The most efficient cruise control in a turbo jet is
The climbing cruise
Transonic airflow across an aircraft
Maybe partly sub sonic and partly supersonic
Which is a stall characteristic of a T tail jet airplane
The nose of the airplane noticeably pitches up
