The confusion might be resolved if we stopped using UK-specific procedures like ‘land after’ and just applied a type of Doc4444 reduced runway separation minima. Military aircrew don’t know what ‘land after’ means either, so they tend to read back ‘cleared to land’ or ‘cleared to land after’ since it only exists in the UK civil scene.
This links into the post about abolishing MATS part 1–why don’t we just use Doc 4444? It’s actually far more comprehensive and more up to date in many aspects.
