RTOW (TEMP ENTRY)
in the FCOM 2.02.12 P5
for a takeoff,weight lower than those displayed on the chart,associated speeds are calculated as follows:
1 For given configuration and wind,note the speeds associated with the takeoff weight in the row displaying the highest permissible temperature.
2 Apply speed corrections provided at the bottom of the RTOW chart to V1,VR and V2 limited to the minimum speeds.
i want to ask if in the RTOW chart (TEMP .ENTRY),the maximum permissible TEMP is 45,and it is permissible take off weight is 74.0 tons and associated speeds V1=152 Vr=153 V2=156. we actual takeoff weight is 67.1 tons. in the RTOW chart ,the Tref (OAT) is 44 .and Tmax(OAT) is 54.
can i set the final value v1=152 vr=153 v2=156 flexible temp=44
or v1=152-7=145 vr=153-7=146 v2=156-7=149 flexible temp=44
