I can’t think of any particular instances where a O or 0 would mix in the cockpit. Switches and panels are always labeled with letters in form of words or abbreviations. Gauges use exclusively numbers for measuring some quantity, for example EGT. In cases where numbers and letter might mix there are specific rules about not using O or 0 or even 1 and L.

- bronco21016 8y agoYes but I believe they’re not permitted to both be used in an individual airport identifier. KORD or 07G are valid but 07O would not be. Just the same as they’re not both permitted in the same aircraft registration.
- marcosdumay 8y agoA lot of things that people do not actually do are permitted. And this specific rule (how to use numbers in airport codes) is completely country dependent, there is no standard.
