|
geometric twist |
decrease in angle of incidence from wing root to wingtip. T-6 is geometrically twisted |

|
adverse yaw |
tendency for a/c to yaw away from direction of aileron roll input fix with spoilers, rudder input, differential ailerons |
|
|
dorsal fin location and purpose |
front of vertical stabilizer, to increase its surface area, slow spin rate, and aid in stopping autorotation |
|
|
ventral fin location and purpose |
beneath empennage, slows spin rate and aid in maintaing nose don |

describe skid vs slip |
skid - too much rudder, decreased turn radius, increased turn rate slip - too little or opposite rudder, increased turn radius, decreased turn rate |

Instrument spin indications |
erect - altimiter decreasing, AoA 18+, a/s 120-135kts, turn needle pegged in direction of spin inverted - altimeter decreasing, AoA 0, a/s 40 kts, turn needle pegged in direction of spin |
|
|
progressive spin |
will result if in recovery phase, pilot puts in full opposite rudder but keeps stick full aft |
|
|
aggravated spin |
wrong rudder input, stick full forward |
|
|
slipstream swirl |
low speed pfactor causes nose to yaw left felt at high power, low a/s |
|
|
takeoff procedures in wind shear |
use longest runway use t/o flaps, delay rotation by amt of wind shear rotate abort if wind shear is encountered near Vrot |
|
|
Landing procedures in wind shear |
Set flaps for takeoff increase approach speed by amt of wind shear Establish proper approach pitch, trim, and power settings by 100AGL expect increased landing distance |
