It's not the same condition. HAF F-16's loadout drag index = 50 which equals 6+ AMRAAMs + pylongs. Hornet's loadout has a drag index of only 17-20.

I was looking at a note I had written down years ago, so lets look at it fresh.

Basic aircraft DI = 7

AIM-9 non-wingtip = 5 (two for 10)

AIM-9 Launcher and adapter = 6 (two for 12)

So we are looking at DI = 29 (so for a "just for me" quick and dirty analysis I MAY have used DI 50 to save time last time)

Basic aircraft weight = 20,200lb

Internal usable fuel = 7,116lb (60% for 4,270lb)

AIM-120 = 341lb (two for 682lb)

AIM-9 = 195lb (two for 390lb)

Launcher and adapter = 98lb (two for 196lb)

Configured weight = 25,738lb

Sea Level: -229 motor

DI 50, 26klb weight, 18.2dps at 0.8M (weight corrected per chart for 25.75klb +.2dps for 18.4dps)

DI 0, 22klb weight, 21.4dps (weight corrected per chart for 25.75klb -3.6dps for 17.8dps at 0.7M, slope from .6 to .7 cover a .8dps increase, so lets bump 17.8 to 18.6dps)

DI = 29 expected result? 18.484

15k: -229 motor

DI 0, 22klb weight, 14.1dps at 0.9M (weight corrected -2dps for 12.1dps)

DI 50 10K, 13.6 corrected to 13.8

DI 50 20K, 9.7 corrected to 9.9

DI 50 15K, expected 11.85

DI 29 expected 11.955dps

So there we have it. Under a rigorous DI and Weight analysis of the -229 motored HAF Block 52 the -402 powered Hornet does indeed beat it. The best Hornet can, under certain circumstances, out Viper the worst Viper.

Out of curiosity DI-50 sea level with -129 reads just a hair over 18.5 and 10 reads 14.2 and 20k reads 10.2 which I would average to 12.2.

I see several ways now I could have arrived at 18.5 for my old estimate, but I don't see how I arrived at 12.63. Maybe I was doing a rigorous with the -129 motor?

Either way, please don't jump to conclusions about the methods I use. If you have a question, ask. I will generally be more than happy to re-run the numbers.
