V_t = (8*S₃*d+V_ex^2)^0.5+15
This formula uses 4 Variables

Variables Used

Threshold Speed for Transition - (Measured in Meter per Second) - Threshold Speed for Transition based on 1.5 times the stall speed.
Distance for Deceleration in Normal Breaking Mode - (Measured in Meter) - Distance for Deceleration in Normal Breaking Mode to a Nominal Takeoff Speed.
Deceleration - (Measured in Square Meter per Second) - Deceleration is defined as the reduction of the speed.
Nominal Turn-off Speed - (Measured in Meter per Second) - Nominal Turn-off Speed Categorization is system for differentiating aircraft based on the speed at which the aircraft turn-off.

STEP 1: Convert Input(s) to Base Unit

Distance for Deceleration in Normal Breaking Mode: 60 Meter --> 60 Meter No Conversion Required
Deceleration: 32.6 Square Meter per Second --> 32.6 Square Meter per Second No Conversion Required
Nominal Turn-off Speed: 80 Meter per Second --> 80 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_t = (8*S₃*d+V_ex^2)^0.5+15 --> (8*60*32.6+80^2)^0.5+15

Evaluating ... ...

V_t = 163.485689546165

STEP 3: Convert Result to Output's Unit

163.485689546165 Meter per Second --> No Conversion Required

FINAL ANSWER

163.485689546165 ≈ 163.4857 Meter per Second <-- Threshold Speed for Transition
