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.
Weight x 1000 lbs. (131 equals a weight of 131,000 lbs)
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
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
