2.4.3 Explain the following:
(a) power must be applied to maintain speed in a level turn
(b) an aeroplane tends to overbank in level and climbing turns and not in
descending turns
2.4.4 Explain the following:
(a) the effect of aileron drag on turn performance at low airspeed
(b) how the following design features offset this drag
(i) frise ailerons
(ii) differential ailerons.
2.5
Performance considerations
2.5.1 Using power required and power available graphs, identify the following:
(a) stall speed (power on)
(b) the region of reverse command (sometimes described as the “back of the
power curve”)
2.5.2 Describe the following terms and cite situations that may result in an aeroplane
exceeding load factor and wing loading limits:
(a) load factor
(b) “g”
(c) wing loading
2.5.3 Given that certain flight conditions remain constant, explain the effect of the
following:
(a) changes in weight and altitude (height) on:
(i) angle of attack and IAS in level flight
(ii) level flight range and endurance
(iii) turn rate and radius
(iv) glide range and endurance
(b) changes in head/tail wind component on
(i) glide range
(ii) endurance
(c) changes in power on turn rate and radius
2.5.4 Explain how the energy state of an aircraft changes with changes in altitude and air
speed
2.6
Stability and control
2.6.1 Explain the effect of the factors listed below on the stability and control of an
aeroplane in each of the following three planes of movement:
(a) longitudinal stability:
(i) position of CG
(ii) movement of centre of pressure
(iii) changes in thrust
(iv) tailplane moment
(b) lateral stability:
(i) high versus low set wings
(ii) dihedral versus anhedral
(iii) sweepback
