Class E airspace is controlled airspace that extends from the surface to a specified altitude, typically 700 or 1,200 feet above ground level (AGL). It is often found around airports that have an operational control tower, as well as in other designated areas. Class E airspace is designed to provide controlled airspace for instrument flight rules (IFR) traffic, as well as to provide separation for visual flight rules (VFR) traffic. It is important for pilots to understand the characteristics and regulations of Class E airspace in order to operate safely and efficiently.
Class E airspace is depicted on aeronautical charts with a dashed magenta line and is labeled with the letter “E.” It is important for pilots to be aware of the specific dimensions and altitudes of Class E airspace in their area of operation. Additionally, Class E airspace can be designated as either surface-based or non-surface-based. Surface-based Class E airspace extends from the surface to a specified altitude, while non-surface-based Class E airspace begins at a designated altitude above the surface. Pilots should be aware of these distinctions and the associated regulations when operating in Class E airspace.

Rules for Operating in Class E Airspace
When operating in Class E airspace, pilots must adhere to specific rules and regulations to ensure safe and efficient flight operations. One of the key rules for operating in Class E airspace is the requirement to establish two-way radio communication with air traffic control (ATC) before entering the airspace. This communication requirement applies to both IFR and VFR operations and helps to ensure that ATC can provide separation and traffic advisories to all aircraft operating in the airspace.
In addition to the communication requirement, pilots must also adhere to specific altitude and clearance requirements when operating in Class E airspace. For example, when operating under VFR, pilots must maintain a minimum altitude of 500 feet AGL, unless operating over open water or sparsely populated areas, in which case they must maintain a minimum altitude of 500 feet above the surface. Pilots must also obtain an ATC clearance before entering certain designated areas of Class E airspace, such as those surrounding busy airports or military operations areas. By following these rules and regulations, pilots can ensure safe and efficient operations in Class E airspace.
Communication Requirements
Communication is a critical aspect of operating in Class E airspace, as it allows pilots to receive important information and instructions from ATC to ensure safe and efficient flight operations. When operating in Class E airspace, pilots are required to establish two-way radio communication with ATC before entering the airspace. This communication requirement applies to both IFR and VFR operations and helps to ensure that ATC can provide separation and traffic advisories to all aircraft operating in the airspace.
In addition to establishing two-way radio communication with ATC, pilots must also adhere to specific communication procedures when operating in Class E airspace. For example, pilots must use the appropriate radio frequencies to contact ATC and should use standard phraseology and procedures when communicating with controllers. By following these communication requirements, pilots can ensure that they receive important information and instructions from ATC to help them navigate and operate safely in Class E airspace.
Weather Minimums
| Location | Minimum Temperature (°C) | Minimum Humidity (%) |
|---|---|---|
| New York | -10 | 20 |
| London | -5 | 30 |
| Tokyo | 0 | 25 |
Weather minimums are an important consideration for pilots when operating in Class E airspace, as they help to ensure safe and efficient flight operations. When operating under VFR in Class E airspace, pilots must adhere to specific weather minimums to ensure adequate visibility and cloud clearance. For example, pilots must maintain a minimum visibility of 3 statute miles and remain clear of clouds when operating below 10,000 feet MSL. Additionally, when operating above 10,000 feet MSL, pilots must maintain a minimum visibility of 5 statute miles and remain clear of clouds by specific distances.
In addition to weather minimums for VFR operations, pilots must also adhere to specific weather minimums when operating under IFR in Class E airspace. These weather minimums are designed to ensure that pilots have adequate visibility and cloud clearance to safely conduct instrument approaches and departures. By adhering to these weather minimums, pilots can ensure that they have the necessary visibility and cloud clearance to operate safely in Class E airspace.
Special Considerations for Class E Airspace
There are several special considerations that pilots should be aware of when operating in Class E airspace. One consideration is the presence of military operations areas (MOAs) within Class E airspace. MOAs are designated airspace where military training activities such as air combat maneuvers take place. Pilots should be aware of the location and altitudes of MOAs when operating in Class E airspace to avoid potential conflicts with military aircraft.
Another special consideration for Class E airspace is the presence of restricted areas, which are designated airspace where flight operations are restricted due to national security or public safety concerns. Pilots should be be aware of the location and altitudes of restricted areas when operating in Class E airspace to avoid violating restricted airspace and potentially facing enforcement actions.
Tips for Navigating Class E Airspace
Navigating Class E airspace requires careful planning and adherence to specific rules and regulations. One tip for navigating Class E airspace is to thoroughly review aeronautical charts and other relevant publications to familiarize yourself with the dimensions and altitudes of the airspace in your area of operation. By understanding the specific characteristics of Class E airspace, pilots can better plan their routes and anticipate potential communication and clearance requirements.
Another tip for navigating Class E airspace is to maintain situational awareness and stay vigilant for other aircraft operating in the airspace. Pilots should use all available resources, such as traffic advisory systems and visual scanning techniques, to identify and avoid potential conflicts with other aircraft. By staying vigilant and maintaining situational awareness, pilots can help ensure safe operations in Class E airspace.
Common Mistakes to Avoid in Class E Airspace
There are several common mistakes that pilots should avoid when operating in Class E airspace. One common mistake is failing to establish two-way radio communication with ATC before entering the airspace. This can lead to potential conflicts with other aircraft and compromise safety within the controlled airspace. Pilots should always ensure that they establish communication with ATC before entering Class E airspace to receive important information and instructions.
Another common mistake is failing to adhere to specific altitude and clearance requirements when operating in Class E airspace. Pilots should always maintain the appropriate altitude and obtain necessary clearances before entering designated areas of Class E airspace, such as those surrounding busy airports or military operations areas. By avoiding these common mistakes and adhering to specific rules and regulations, pilots can ensure safe and efficient operations in Class E airspace.
