NORMAL PROCEDURES
4.1 INTRODUCTION
This section provides amplified procedures for normal operation.
4.2 AIRSPEEDS FOR NORMAL OPERATION
Unless otherwise noted, the following speeds are based on a maximum
mass of 600 kg and may be used for any lower actual mass. However, to
achieve the performance specified in Section 5 for takeo and landing dis-
tance, the speed correction appropriate to the particular mass must be used.
TAKEOFF ROTATION
Normal Flaps +1 45 KIAS
Obstacle clearance Flaps 0 60 KIAS
ENROUTE CLIMB
Normal Flaps 0 or (-) 90 - 110 KIAS
Best rate of climb (SL) Flaps 0 78 KIAS (V
Y
)
Best angle of climb (SL) Flaps 0 60 KIAS (V
X
)
LANDING APPROACH
Normal approach Flaps 0 65 - 75 KIAS
Normal approach Flaps +1 63 - 70 KIAS
Normal approach Flaps +2 60 - 65 KIAS
GO AROUND
Full power Flaps as practical 65 KIAS
Maximum demonstrated crosswind velocity
Takeo or landing 18 Knots
