The ASA E6B Circular and its companion products for high speed and high altitude flight are specialized tools used by pilots for performing various calculations during flight planning and in-flight operations. Here’s a breakdown of each component:

ASA E6B Circular:

• This is the core flight computer, featuring a circular slide rule design made of durable plastic.
• It allows pilots to perform a wide range of calculations, including:
  • Basic arithmetic (addition, subtraction, multiplication, division)
  • Flight planning computations (distance, time, fuel consumption, wind correction)
  • Complex in-flight calculations (true airspeed, density altitude, pressure altitude, off-course correction)
  • Conversions between units (feet/meters, knots/mph, gallons/liters)
• The “wind side” of the computer uses a graphical method to solve wind-related problems, such as true airspeed, ground speed, and true heading.
• The E6B Circular is a popular choice for its ease of use, accuracy, and affordability. It’s a staple tool for most pilots but may not be sufficient for aircraft flying at very high speeds or altitudes.

High Speed E6B Circular:

• This is a product designed for aircraft operating in the high-speed range (220-700 knots).
• This allows pilots to perform accurate calculations related to true airspeed, ground speed, time, and distance relevant to high-speed flight.
• Ideal for pilots flying jets, turboprops, and other high-performance aircraft.

High Altitude Companion:

• There isn’t a single specific “High Altitude Companion” that comes with the E6B Circular.
• However, several resources specifically address high-altitude considerations:
  • High Altitude Supplement: This booklet by the FAA provides information on the effects of high altitude on aircraft performance and flight procedures.
  • E6B Circular Instructions: The instruction manual for the E6B Circular itself often includes specific sections or examples related to high-altitude calculations.
  • Online resources: Many websites and apps offer high-altitude calculators and planning tools.

Overall:

The ASA E6B Circular, combined with the High Speed E6B Slide and knowledge of high-altitude considerations, equips pilots with a powerful toolset for accurate and efficient flight planning and navigation in a wide range of flight conditions, including high speed and high altitude environments.
