Where is VFR on top prohibited?

VFR on top (Visual Flight Rules on top) refers to a type of flying in which a pilot operates under visual flight rules while flying above clouds or other weather conditions that would normally require instrument flight rules. While VFR on top can provide flexibility and efficiency to pilots, there are certain areas where this type of operation is prohibited for safety and airspace management reasons.

One area where VFR on top is prohibited is in Class A airspace. Class A airspace encompasses the airspace above 18,000 feet in the United States and is primarily used for high-altitude, instrument flight rule operations. Since VFR on top operates under visual flight rules, it is not permitted in Class A airspace as it requires pilots to rely on visual references rather than the required instrument procedures.

Another area where VFR on top is prohibited is in areas with specific airspace restrictions such as military operation areas (MOAs), prohibited areas, and restricted areas. These areas are established to ensure the safety of military operations or to protect sensitive locations. Flying VFR on top in these areas could potentially interfere with ongoing operations or compromise security.

Additionally, VFR on top is generally not allowed in certain controlled airspace, such as Class B and Class C airspace. These types of airspace have a high volume of traffic and require strict air traffic control procedures. Flying VFR on top in these areas can pose a risk of collision with other aircraft and disrupt the flow of air traffic.

It is important for pilots to familiarize themselves with airspace regulations and restrictions before planning a flight. This includes understanding where VFR on top is prohibited to ensure compliance with aviation regulations and maintain a high level of safety in the skies.

FAQs About VFR on top Prohibitions

1. Can a pilot request VFR on top in Class B airspace?

In most cases, VFR on top is not allowed in Class B airspace due to the high volume of air traffic and the need for strict air traffic control. However, pilots may request VFR on top if they can demonstrate a clear need and obtain clearance from air traffic control.

2. Are there any exceptions for VFR on top in restricted areas?

Generally, VFR on top is prohibited in restricted areas to ensure the safety and security of sensitive locations. However, there may be certain circumstances where a pilot can obtain special permission or clearance to fly VFR on top in these areas.

3. Are there any altitude restrictions for VFR on top flights?

While there are no specific altitude restrictions for VFR on top flights, pilots must comply with airspace requirements and separation standards. It is important to maintain a safe altitude to ensure proper separation from other aircraft and to comply with applicable regulations.

4. Can VFR on top be requested in Class C airspace?

VFR on top is generally not allowed in Class C airspace due to the high volume of air traffic and the need for strict air traffic control. Pilots are expected to adhere to instrument flight rules when operating in Class C airspace.

5. Can VFR on top be requested in a military operation area (MOA)?

VFR on top is typically not permitted in military operation areas (MOAs) as these areas are designated for military training and operations. Flying VFR on top in a MOA can interfere with ongoing military activities and compromise airspace safety.

6. Is there a minimum visibility requirement for VFR on top operations?

While there is no specific visibility requirement for VFR on top operations, pilots must maintain visual meteorological conditions and have adequate visual references to ensure safe navigation and separation from other aircraft. It is essential to exercise good judgment and adhere to visual flight rules when operating under VFR on top.

7. Can a pilot request VFR on top in Class D airspace?

VFR on top is generally allowed in Class D airspace, which is typically controlled airspace surrounding smaller airports. However, it is subject to air traffic control approval and pilots must comply with any applicable restrictions or requirements.

8. Why is VFR on top not allowed in Class A airspace?

Class A airspace is primarily used for high-altitude, instrument flight rule operations. VFR on top relies on visual references, which are not sufficient in Class A airspace. Instrument flight rules and proper instrument procedures are required for safe operation in this airspace.

9. Are there any restrictions on VFR on top at night?

There are no specific restrictions on VFR on top at night, but pilots must adhere to applicable regulations and ensure adequate visibility and visual references for safe navigation. Flying above clouds at night can pose additional challenges due to limited visual cues, so pilots should exercise caution and be prepared for any necessary instrument flight.

10. Can VFR on top be requested in a Control Zone (CTA)?

The permissibility of VFR on top in a Control Zone (CTA) depends on the specific regulations and procedures of the controlling authority. Pilots should consult the relevant aviation authorities or air traffic control to determine if VFR on top is allowed in a particular Control Zone.

11. Are pilots required to file a flight plan for VFR on top flights?

Flight plan requirements for VFR on top flights can vary depending on the jurisdiction and the specific flight conditions. It is generally advisable to file a flight plan to ensure proper communication and search and rescue assistance in case of an emergency.

12. Is VFR on top allowed in Class E airspace?

VFR on top is generally allowed in Class E airspace, which is commonly controlled airspace that extends beyond Class D airspace. However, pilots should be aware of any applicable restrictions or requirements, and they must comply with air traffic control instructions and maintain appropriate visual references for safe operation.
