Yeah you would just go full throttle with + and control and practice manually flying downrange. The pad azimuth is fine for just flying a simple pitch over trajectory with no roll, ballistic flights were targeted to come down in the Indian Ocean, apogee would be around 900 km. The Atlas A won't get you that far, it was just a test of the booster engines and had no sustainer engine and staging capability, so it doesn't go as far as the later models.
