With our OpSpecs we can takeoff down to 1200 RVR. Doing research in the FAR and also in the Everything Explained for the Professional Pilot I found a partial answer to my question. At airports without RVR reporting you may take off with 1/2sm or the lowest CAT I minimum. That is straight forward, except what about airports where the lowest CAT I minimum is higher than 1/2sm?
For example what about KEGE where the visibility minimums are 3sm and the ODP uses standard takeoff minimums. (If you can make the climb gradient) If you are approved for lower than standard takeoff minimums do you have to use the 1/2sm or 3sm?
Thanks for the education.
