Which of the following is correct for a jet aircraft take-off paramete

1.	Which of the following is correct for a jet aircraft take-off parameter (TOP)?(a) TOP = \(\frac{W/S}{σCL \frac{T}{W}}\)(b) TOP = \(\frac{1}{σCL \frac{T}{W}}\)(c) TOP = \(\frac{2}{σCL \frac{T}{W}}\)(d) TOP = \(\frac{W}{σCL \frac{T}{W}}\)This question was posed to me in quiz.I need to ask this question from Wing Loading topic in section Thrust-Weight Ratio and Wing Loading of Aircraft Design
Answer» The correct answer is (a) TOP = \(\FRAC{W/S}{σCL \frac{T}{W}}\) To explain: Take-off PARAMETER is used to determine take-off distance for the aircraft. TOP is affected by wing loading and THRUST loading both. Hence, proper estimation of such parameters are crucial. TOP for jet and prop DRIVEN will be different. For jet, TOP = \(\frac{W/S}{σCL \frac{T}{W}}\).
