PS Anybody know of a spec that has included sustained g before this one?
My understanding is that F-35 has a 4.5G sustained turn requirement. But one must be careful when comparing such a number. Altitude, fuel state, payload, and external stores can all affect sustained turn. Many of the trainers on the market for example can already meet
a 6.5G sustained turn requirement. But they cannot meet the T-X's specific requirement which includes fuel state, payload, and altitude. I understand that altitude is what prevents the Hawk and M-346 from being compliant.
