given in the higher row. Thus, if your data table contains data for the
weights of ‘200’, ‘400’, and ‘600’, FDC Live Cockpit! 2011 will use the
‘200’ row for weights between ‘200’ and ‘399’, the ‘400’ row for
weights between ‘400’ and ‘599’, and the ‘600’ row for weights over
‘600’. The rows should be sorted in descending order. If you want a
row to be valid for all weights, simply enter ‘000’ in the column (it is
generally a good advice to let the last row in the table read ‘000’).
Note! Entering data with short weight intervals will make a more
detailed and accurate performance file for your aircraft.

Required:Yes
V1 The takeoff decision speed
The takeoff decision speed in knots. When the aircraft exceeds this
speed, it may not be possible to stop the aircraft on the runway in
case of a rejected takeoff (RTO).
Speed in knots.
Required:Yes
VR The rotation speed
The rotation speed in knots. This is the speed at which the pilot raises
the nose to lift off the runway during the takeoff roll. VR should be
greater than or equal to V1.
Speed in knots
Vr >= V1
Required:Yes
V2 Minimum takeoff safety speed
The minimum takeoff safety speed in knots. This is the minimum safe
flying speed should an engine fail immediately after takeoff. V2
should be greater than or equal to VR.
Speed in knots
V2 >= VR
Required:Yes
