Even if you have speed for an air start you ain't gonna do that in the pattern. No one has mentioned how long it takes to get a good air start. As mentioned above, just no time for that below a couple thousand feet. And Dash-1 eject guidance? The air start argument is BS.
Correct. In the scenario of an instrument approach, the biggest problem isn't airspeed, it is how much altitude you have below you and thus time to get the motor re-lit. Even at best glide, from 1600' you are probably just barely getting the JFS online, much less a good restart of the motor. And I agree, 250 knots is plenty comfortable in any fighter aircraft I've ever flown.
