Basic relationships Some ‘rules of thumb’ Approach speed lies between 1.45 and 1.62 V stall . W/S = 0.5 V 2 C L in the ‘approach’ condition. Approach C L lies between C Lmax /2.04 and C Lm
Table 9.3 The ‘first approximations’ methodology
Estimated parameter 1. Estimate the wing loading W/S. 2. Check C L in the cruise. 3. Check gust response at cruise speed. 4. Estimate size. 5. Estimate take-off wing loading and T
