    approach speed info

    For my 4th novel I need some info on approach speeds. I just like to be a little accurate on these things. In my fiction I have a C-130 on about 5 mile final flying into about a 20 knot headwind. About 1o miles out a Gulfstream G5 is turned over by the TRACON smoking along the ILS. The tower controller tells the G5 he is #2 following the C130. My question is this.

    Given the scenario above, what do you think the approach speed of the C130 is and what speed could the G5 realistically slow down to?

    Thanks

    Approach speed for a C130 roughly 5 mile final is normally in the ballpary of 160-170, with a 20 kt headwind my guess would be 130-140ish

    a G5 with a 20 kt headwind?... 120 kts on a short final is my guess. Ive seen it plenty. 10 mi final probably around 190ish

    thank you Polo708. For my story, I was hoping the approach speed of the G5 would be much faster than the C-130 as overtaking the C-130 was in my plans. However, after thinking about it and putting this old head back into ATC and pilot mode, I realized there were a lot of wasy to write it without worrying about the speed. The 4th novel is called Long Runway and a lot of it takes place out at Gabreski where the air national guard has C-130. Thanks again for your input.

    Those G5's can get down to an insanely low stall speed, especially with a 20 kt. headwind. Something older like an MD-80 would struggle to slow down that much and may work better if you're trying for an overtake situation, haha. Good luck on the book. I'm looking forward to it
