Chapter 4, Yikes!
This is the lowest mach number that will create sonic airflow somewhere on the aircraft.
What is Critical Mach Number ?
The T-6B Load Limit is designed to be less than the ______ of individual components, This virtually guarantees the airplane will reach its expected service life
What is the elastic limit?
T-6B Ultimate Load factor is this much bigger than its Load limit factor.
What is 150%
This Causes Autorotation.
What is asymmetrically stalled wings
These three factors determine the strength of wingtip vorticies.
What is Weight, speed and wing shape.
Heavy, Clean, slow.
This is the boundary that separates Normal Command from Reverse Command.
What is Cruise Endurance Velocity? Or Cruise endurance AOA, (8.8 Units) Or Lowest point on the Pr Curve.
It is forbidden to purposely enter this spin in a T-6B.
What is a Inverted Spin?
This is the recommended Speed when traveling through turbulence in a T-6B.
What is 180KIAS
Max speed is 207KIAS
This is the location of the spin axis on the T-6B.
This is the primary hazard of wake turbulence
What is induced roll.
These four factors determine the Coefficient of Friction.
What is Runway Surface, Runway Condition, Tire type, and Degree of brake application.
This axis is used to determine the direction of P-Factor yaw.
What is the Thrust Axis?
Asymmetric loading and Gust loading have these load limits.
What is 4.7G's and -1G's or 2/3rds of limit load factor.
These design features reduce the severity of spin characteristics
What is Dorsal fin, ventral fin, and strakes
This is the definition of wind shear
Sudden change in wind direction and or speed over a short distance. Can be vertical or horizontal and vary in intensity.
Turn performance is measured using these two parameters.
What is Turn Rate and Turn Radius?
Only Airspeed and AOB are control these parameters.
Turn Rate and Turn Radius are independent of this.
Weight!
This speed is the VBEST speed for glide range for T-6B
What is 125 KIAS.
This spin is aerodynamically impossible for the T-6B to enter.
What is a flat spin.
This is the best technique for dealing with wind shear.
Avoid it! pg.170 first sentence
This Divergence happens when you have strong Directional stability and weak lateral stability.
What is Spiral Divergence?
This is the definition for Maximum cruise endurance
Max angle of climb speed for the T-6B
Not flown, but it is 140 KIAS.
Spin Recovery, Go!
1. Gear Flaps speed brake retract.
2.PCL IDLE
3.Rudder, Full opposite of spin Direction
4. Hold stick forward of neutral, ailerons neutral
5. Slowly pull up to level flight after rotation stops.
This is the minumum take off and landing spacing for wake turbulence.
What is 3 minutes for landing 2 minutes for takeoff.
