Static and dynamic longitudinal stability 19
The aft CG limit can be determined by the: - ANSWER>>minimum
acceptable static longitudinal stability.
What happens if the CG is located beyond the forward CG limit? -
ANSWER>>This can lead to an unacceptably high value of manoeuvre
stability.
The neutral point of an aeroplane is the point where: - ANSWER>>the
aeroplane becomes longitudinally unstable when the CG is moved
beyond it in an aft direction.
The max aft position of the centre of gravity is amongst others limited
by the: - ANSWER>>minimum value of the stick force per g.
How can a pilot recognise static stick force stability in an aeroplane
during flight? - ANSWER>>To maintain a speed above the trim speed
requires a push force.
A phugoid refers to: - ANSWER>>dynamic longitudinal stability.
The stick force stability and the manoeuvre stability are positively
affected by: - ANSWER>>A forward CG movement in case of the stick
force stability and a forward CG movement in case of the manoeuvre
stability.
, Given an aeroplane in steady, straight and level flight at low speed and
considering the effects of centre of gravity (CG) location and thrust, the
highest value of wing lift occurs at: - ANSWER>>forward CG and low
thrust.
If an aeroplane exhibits insufficient stick force per g, this problem can
be resolved by installing: - ANSWER>>a bobweight in the control
system which pulls the stick forwards.
Phugoid - ANSWER>>oscillations of a high amplitude
When an aeroplane with the centre of gravity forward of the centre of
pressure of the combined wing/fuselage is in straight and level flight,
the vertical load on the tailplane will be: - ANSWER>>downwards.
The purpose of the horizontal stabilizer is to: - ANSWER>>give the
aeroplane sufficient longitudinal stability.
curva para abajo - ANSWER>>mayor estabilidad
The short period mode is an: - ANSWER>>oscillation about the lateral
axis.
Which statement on dynamic longitudinal stability of a conventional
aeroplane is correct? - ANSWER>>Damping of the phugoid is normally
very weak.

acceptable static longitudinal stability.
