And what happens if the incoming plane goes missed? You're assuming an
awful lot about what the tower guy can and cannot see.

My home field tower doesn't have radar, or a brite scope slaved from the
approach control.

If there's an incoming IFR flight, and you want to go out IFR, you are
not going to be released until the incoming plane either lands or
cancels IFR.

At a towered airport you are talking runway separation. After the first
plane is 3000 feet down the runway the next one can be launched.



For the same reason a plane holding for IFR release cannot take off
until the IFR arrival he's waiting for has either cancelled IFR or has
landed.


No. The tower can provide visual separation if it doesn't have radar.
