I understand that, but The F-5 doesn’t have as much power as the F-18 for example. I know that using SB on final in the T-38 is forbidden, because of the power restriction, I wanted to know if there is some kind of criteria for using SB or not, something like config, temperature, weight. Also if there is some kind of correction on the final approach speed calculation considering when they are deployed. I know that will keep the RPM higher, but the F-5 approaches deep inside the reverse command area, don’t know about other jets. Thanks for the help so far.
