, V
R
and V
2
Speeds
• Refer to TABULATED TAKEOFF DATA Sub-section 5.20.
To Determine Final Take-Off Climb Speed (V
FTO
)
• Enter Figure 5.10.1 with the airplane weight.
• Move up the chart and intersect the curve.
• Move horizontally across the chart and read the FINAL TAKE-OFF CLIMB SPEED -
knots IAS scale.
To Determine En-Route Climb Speed (V
ERC
)
• Enter Figure 5.10.2 with the airplane weight.
• Move up the chart and intersect the curve.
• Move horizontally across from the intersection and read the SPEED - knots IAS scale.
To Determine Landing Reference Speed (V
REF
)
• Enter Figure 5.10.3 with the airplane weight.
• Move up the chart and intersect the curve.
• Move horizontally across the chart and read the SPEED - knots IAS scale.
To Determine Power Off Stalling Speeds (V
S
)
• Enter Figure 5.10.4 with the airplane weight.
• Move up and intersect the curve appropriate to the required configuration.
• Move horizontally across the chart to the reference line and then parallel with
the guidelines to the field pressure altitude
intersection.
• Move horizontally across the chart from the intersection of the field pressure altitude and
read the STALLING SPEED - knots EAS from the right hand scale.
NOTE: V
S
is determined at the forward center of gravity limit, including the variation with
weight, as given in Section 2 - LIMITATIONS Figures 2.1 and 2.2. V
S
will
decrease as the center of gravity moves aft.
