AE104 - Performance and Maneuvering Flashcards
______ is the greatest factor in takeoff distance.
Weight
If the weight is doubled, takeoffdistance will almost quadruple
The minimum speed for takeoff is approximately ___% above the power-off stall speed.
20%
What 3 factors will cause a higher DA on takeoff/landing?
high airport elevation, higher temperature, increased humidity
What is max rate of climb?
Gaining the most altitude in a given amount of time
140 KIAS
What is maximum angle of climb?
Most altitude for distance traveled
Not flown in the T-6 since best rate of climb will meet or exceed any obstacle clearance requirements
What are 3 factors that affect cruise performance?
Weight
Altitude
Configuration
Mach number is the ratio of: _________
TAS/Local Speed of Sound
Critical Mach number is defined as the ________________________
Mach number that produces the first evidence of local supersonic flow
Define Best Glide Speed
The airspeed flown power off which provides maximum range.
Speed is based on L//Dmax
125 KIAS
What is the glide ratio of the T-6 with the gear, flaps and speed brake up, and propeller feathered?
11:1
Glide range remains the same regardless of what aircraft change?
Changes in weight have no effect on glide range, but decrease glide endurance.
For landing, the final approach speed is usually ____ times the stall speed for any aircraft.
1.3
In the T-6, what is the primary means of compensating for engine torque?
The automatic Trim Aid Device (TAD)
If the free airstream relative wind is ABOVE the thrust line (such as a power-on descent), which way will the nose yaw and what is the corrective action?
The nose will yaw to the right. Corrective action is to apply left rudder.
Which rudder direction compensates for Slipstream Swirl?
Right Rudder
What is the primary means for compensating for gyroscopic precession forces from the propeller?
The Trim Aid Device (TAD)
During a turn, lift is divided into what 2 components?
Horizontal component
Vertical component
Standard rate turn is __º per second
3º
Turn rate and radius are based on what 2 factors?
Velocity
Bank Angle
What is a slip?
What is a skid?
Slip: A turn with not enough rudder applied, causing a decrease in turn rate and increase radius
Skid: A turn with too much rudder applied, causing an increase in turn rate and decrease in turn radius
What increases G-Loading in a level turn?
Increasing the bank angle
What is an Asymmetric load?
Anytime the ailerons or rudder are deflected in flight, or there is a yawing moment produced by uneven weight distribution.
What is maneuvering speed?
The speed above which full or abrupt control movements in one axis can result in structural damage to the aircraft.
227 KIAS
Load factor is the ration of the _____ divided by the _____.
the load divided by the weight
Why are Asymmetric G limits lower than Symmetric G limits?
The lift on the up-going wing is experiencing more G than what is read on the accelerometer
What is the term for the initial tendecy of an object to return to its original equilibrium?
positive static stability
If an object has positive/negative/neutral dynamic stability, what type of static stability must it have?
Positive Static Stability
What 2 forces have an effect on longitudinal static stability?
Lift and Weight
The difference between the flight path and the longitudinal axis is called ________ ________.
Sideslip Angle
What is the greatest positive contributor to direction static stability?
The vertical stabilizer.
What is the purpose of Dihedral Wings?
Causes an increase in angle of attack and lift on the down going wing during a sideslip. Wing Dihedral is the greatest positive contributor to lateral static stability.
What is Directional Divergence?
A result of negative directional static stability in an aircraft.
An aircraft with directional divergence will continue to yaw and increase its sideslip angle in response to a small initial sideslip.
What is Spiral Divergence?
Caused by an airplane with weak lateral stability, sensing a new relative wind.
The aircraft will continue to yaw and roll in reaction to an initial sideslip resulting in a tight descending spiral. The advancing wing will create more lift and causes the plane to continue to roll.
Dutch roll is a combination of strong _____ stability and weak _____ stability
Strong lateral stability
Weak direction stability
What is Proverse Roll?
The tendency for an airplane to roll in the same direction as it is yawing.
More prevalent in swept wing aircraft
What is Adverse Yaw?
The tendency of the airplane to yaw away from the direction of aileron input.
Caused by more induced drag on the up-going wing.
What is a PIO?
What causes a PIO?
How is the problem corrected?
Pilot Induced Oscillation
In the pitch axis, is a result of the pilot and the inherent longitudinal stability of the airplane simultaneously trying to correct for the same oscillations.
To correct, either neutralize the stick or freeze the stick just aft of neutral.
