Flight Characteristics
Warning: At speeds above Va, full control inputs will only be applied…
slowly and smoothly
Warning: At Vne exceeding what fraction of full deflection range will damage the aircraft? Avoid what kind of movements?
1/3 full deflection. Avoid sudden and abrupt movements
Warning: Do not exceed what airspeed in strong turbulence?
Vra
Va
Maneuvering airspeed
Vne
Velocity never to exceed
Vra
rough airspeed
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
