Table 2 6
The maximum speed for initiation of recovery from dive should be 30 km/h
below the allowed speeds indicated in Table 2.5, with the pitch angle
changing by 20°, and 15 km/h below these speeds with the pitch angle
c:hanging by W.
The maximum change of the pitch angle from the initial setting in the hori-
zontal flight at a given speed should not exceed 20° in execution of zoom.
Warning: Entry in dive and recoveryfrom zoom within a period oftime less
than 5 to 6 seconds are not allowed.
(20) To prevent the main rotor overspeed above the maximum allowed limits
in transient conditions offlight never reduce the main rotor collective pitch
at rates of 1 deg/s or more with the helicopter pitch angle rising simulta-
neously at rates of 1 deg/s or more.
(21) To avoid possible hitting of the tail boom by the main rotor blades:
- Never change the main rotor collective pitch in execution of zooms and
dives.
- Never try to sharply reduce the main rotor collective pitch with the control
stick being simultaneously sharply pushed forward and subsequently
putled back in execution of transient maneuvers.
