-
TAKEOFF CX AND PROCEDURE
·
Gradually
increase collective pitch to hover at 5ft (1,5 m). Check engine and mechanical
contols instruments (NR≈
= 406rpm), no warning light.
·
Increase
Air speed with the HIGE power until IAS = 40 kt (74 km/h), then begin to climb so as to clear 20 ft (6
m) at IAS = 65 kt (120 km/h).
CLIMB
Above 100 ft (30 m) select
Maximum Countinous Power and Optimum Climbing Speed of (Vy) :
IAS = 65 kt (120 km/h) – 1 kts
per 1000 ft (2 km/h per 300 meter)
CRUISE
Fast cruise is obtained by the
first limitation reached corresponding to the begining of the FLI amber area :
Corresponding mechanical limit Tq
or Ng are pointed out with underlined numerical value.
Economic cruise : set Tq to 10%
less than MCP Tq.
Reduce indicated airspeed in
turbulence.
NR ≈ = 412 rpm in low altitude until 414 rpm in high altitude.
APPROACH AND LANDING
-
APPROACH
·
Perform
approach at a minimum rate of descent and at ≈ = Vy.
·
At
approximately 100 ft (30m), reduce airspeed down to HIGE at 5 ft (1,5 m)
·
Approach
check :
1.
Landing
light : AS REQUIRED
2.
All
parameters : CHECK.
-
LANDING
·
In
hover, gradually reduce collective pitch until touch-down, then fully reduce
collective pitch.
