Vt
max aerotow airspeed)
Warning: Airbrakes should not be opened above what airspeed
Vne
Warning: at speeds above Va extend the airbrakes gradually, allowing approximately how many seconds from closed to full extension?
2 seconds
Caution: when exceeding how many degrees nose low, it is possible to exceed what airspeed with airbrakes open?
45* nose low, exceed Vne
Full stalls are characterized by:
Nose drop (G-break) and possible wing drop
A natural stall warning occurs….above the stall speed and consists of a light airframe buffet.
2-4 KIAS
When airbrakes are extended, stall speed increases by how much?
2-4 KIAS
Caution: During stalls with airbrakes deployed, the airframe buffet from the airbrakes may mask what?
The natural stall warning indications
What is the altitude loss from stalls?
80-160 ft
Stall recovery is accomplished by …. (3 Rs)
Relax back stick pressure, Roll wings level, recover
Why does the airspeed indicator reading oscillate during a stalled condition?
Because of turbulent air influencing the nose-mounted pitot tube.
Caution: not all stalls experience a clean nose or wing drop, excessive….shown on the variometer may also indicate a stalled condition
sink
Spin entry is signified by
nose and wing drop and autorotation
Spins are characterized by:
low wind noise, autorotation, low G forces, and slower speeds
What is the altitude loss per rotation for an upright spin?
approx. 320 ft
What is the altitude loss per rotation for an inverted spin?
approx. 580 ft
Nearly all spins range from ….seconds per turn, with a steep altitude of …. degrees nose low.
3-6 seconds, 60-80* nose lose
What do airbrakes do to the yawing motion if extended during a spin entry.
Slow or reduce yawing motion
When control inputs are neutralized, the aircraft should stop spinning in how many turns?
One turn or less
When a flight manual spin recovery technique is used, recover occurs usually in how many turns?
half a turn, or 180* or less
What is the average altitude lost during a flight manual recovery?
600 ft
If controls are held neutral for recovery instead of a flight manual recovery, what is the average altitude lost during recovery ?
700 ft (100 ft more than flight manual recovery)
If the flight manual recovery is completed improperly (forward stick before opposite rudder) what is the average altitude lost during recovery?
830 ft
Warning: Should controls be released in an attempt to recover from a spin?
No, they may float to a pro-spin position and it may not be recoverable from the spin. This is not the same as neutralizing the controls.
Spins that degrade into a dive, spiral dive, or stop spinning altogether in less than 3 full turns with pro-spin controls held are defined as what kind of spin?
Incipient spins
What are the three spin modes?
Upright, inverted smooth, and inverted oscillatory
Caution: Why do Airspeed indications become erroneous at high yaw angles of a spin?
Because the static vents on the sides of the fuselage are bypassed asymmetrically
The TG-16A is more prone to enter a spin in the ….CG positions than …. CG positions.
More prone in far aft CG positions than forward or mid CG positions.
Warning: If proper turn coordination is not exercised near a stall, a spin may occur with only what inputs?
Stick inputs (Such as a stud doing an uncoordinated nose high stall and falling into a spin)
Warning: A three second spin and subsequent recovery to level flight, started below approximately 800 ft may result in?
Ground impact
Spiral Dives are recovered by:
easing the control stick forward and applying opposite rudder and aileron until the aircrafts bank angle is 45* or less. Then smoothly increase back stick pressure and recover to level flight.
Spiral dives are characterized by:
greater G forces, greater wind noises, and the aircraft turning into a tightening spiral
During a spin, if airspeed increases through 60 KIAS, the aircraft may have transitioned into what?
A spiral dive
Warning: Since the aircraft will accelerate into a spiral dive quickly due to weight and efficiency, when pulling out of the dive what must be observed to avoid possible over-G and structural damage?
The permissible control surface deflections at Va and Vne
Warning: If airbrakes are applied abruptly at speeds above Va, what will occur?
Instantaneous over-G and structural damage. Smooth application of airbrakes will minimize this possibility.
TAS
true air speed
IAS

Warning: Does the sailplane have “terminal” airbrakes? What does this mean?
No, it doesn’t have terminal airbrakes meaning it is possible to exceed Vne with airbrakes fully extended with a nose down pitch greater than 45*.
Warning: Should airbrakes be opened above Vne?
