Which weather requirements must be met to operate VFR-on-top?

When operating VFR-on-top, it is essential to adhere to VFR cloud clearance requirements. This means that pilots need to maintain specific distances from clouds to ensure they are compliant with regulations governing visual flight rules. VFR-on-top allows pilots to operate at an altitude above the clouds while still maintaining visual reference to the ground, which is why cloud clearance becomes crucial.

To explain this further, while VFR visibility requirements are important for general VFR operations, they do not directly apply to the unique scenario of VFR-on-top. Rather, pilots must stay clear of clouds according to VFR rules to avoid becoming IFR (Instrument Flight Rules) when flying above the cloud cover. An IFR flight plan is typically required for VFR-on-top operations, but that doesn't affect the immediate weather requirements—rather, it involves proper filing and communication. Lastly, stating that there are no specific weather requirements would be incorrect, as flying VFR-on-top does necessitate particular conditions to ensure safety and compliance with aviation regulations.
