CYA 4" Micro Circular E6B Flight Computer - Pocket Aviation Calculator

About this item

• PATNETED IN USA-Made from waterproof plastic material, Built-in scale, more lighter, smaller, less prone to break easy rotating parts.
• One-Handed Micro Configuration: Measuring 4-1/4 inches in diameter, this pocket slide rule is scaled down specifically for single-handed navigation adjustments and quick cockpit access.
• Sandwich Printing Protection: Logarithmic grids and numeric values are embedded safely inside the plastic layers, providing complete resistance to surface scratches and oil smudges.
• Essential Flight Tracking: Computes standard aviation mathematical variables including flight time, ground speed, fuel burn rates, density altitude, and true airspeed conversions.
• Impact-Resistant Polymer: The thin, lightweight, and waterproof plastic construction minimizes weight in flight gear kits while remaining flexible enough to resist fracturing.
• Mechanical Reliability Line: Operates fully as a battery-free navigation instrument, serving as a tactical backup during avionics or power failures in high-altitude environments.
