NORMAL PROCEDURES
4.0 GENERAL
This section describes the procedures to be adopted for normal operations of the J230-D aircraft.
The procedures are arranged in the sequence considered to be the most desirable and therefore
steps should be performed in the order listed unless good reasons for a deviation exist. The lists
below include checks for all optional equipment, so checks that do not apply to this aircraft may be
skipped.
4.1 SPEEDS FOR NORMAL OPERATION
Unless otherwise noted, the following speeds are based on a maximum weight of 600 kg (1323lb)
and may be used for any lesser weight.
Note that generally the best rate of climb speed & best angle of climb speed are not used during
normal operations. This is because they place a higher degree of stress on the engine & leaves a
relatively small margin to cope with gusts, turbulence etc. The higher climb speeds below are
recommended for all cases where a slight decrease in the aircraft’s climb rate is acceptable. In
cases where maximum climb performance is required then V
X
or V
Y
must be used.
Take-Off:
T.O.S.S. (Speed @ 50 ft) ............................. 65 KIAS
Normal Climb Out ......................................... 80 KIAS (Take Off Flap)
Climb, Flaps Up:
Initial (scheduled climb) ................................ 80 KIAS
En-route ....................................................... 90-100 KIAS
Landing Approach:
V
REF
(Speed @ 50 ft) .................................... 65 KIAS
Baulked Landing ........................................... 65 KIAS Initially
Maximum Recommended in Turbulence:
All Weights ................................................... 112 KIAS
4.2 BEST ANGLE OF CLIMB SPEED
V
X
– Best Angle of Climb Speed ................... 58 KIAS
4.3 BEST RATE OF CLIMB SPEED
V
Y
– Best Rate of Climb Speed ..................... 78 KIAS
