error_401: If there is no side step approach chart then you are now doing a circling app proceedure even though you are just sliding across to another runway. So in the event of a missed app you must follow the proceedure for the original app runway unless ATC clear you differently.
Circling with prescribed tracks!
Basically you follow the published missed app proceedure on the chart. However you are flying three approaches in one here so be very careful!
1)The intrument app....follow the charted MA proc.
2)The prescribed track....this is not your normal visual app, you must stay on the prescibed track until you can intercept your final app path visually, if you must GA, then follow the charted MA proc.
3)The visual app....stay within your circling area defined by your aircraft category and turn towards the runway,climb to charted MA alt and possition your aircraft to intercept the original MA proc.
These approaches can be used in some very nasty areas, generally with mountains or high terrain surrounding the runway and probably crap weather. Good luck.
