Gen Nav Problem

[NinjaBill]

ill give question 2 a shot...

An aircraft is flying TAS 180 knots and tracking 090°T. The W/V is 045/50. How far can the aircraft fly out from its base and return within 1 hour?

Using these figures in my crp, the aircraft will fly at a GS of 141kts outbound, and return with a ground speed of 211kts

If t is measured in hrs

141 x t = 211 x (1-t)

141t/211 = (1-t)

0.668 t = 1-t

1.668 t = 1

t = 0.599

so the ac flys at 141kts for 0.599 of an hr

so travels for 0.599 x 141 = 84.5 NM

we can check this as the aircraft will return for (1-0.599) hrs at 211kts

= 0.401 x 211

= 84.6NM (rounding errors as im only using 3 dp for calcs)
