What is a Dutch Roll? The Aircraft Maneuver Every Pilot Should Know

In aviation, Dutch roll refers to a potentially dangerous flight instability where an aircraft experiences a combination of yaw and roll oscillations. It can either be a specific maneuver or a naturally occurring aircraft phenomenon. Definition and Dynamics of the Dutch Roll Dutch roll is an aircraft motion where the tail is wagged side to side (yaw) while the wings rock from side to side (roll), with both movements occurring out of phase. It is caused by aerodynamic coupling between the yaw (side-to-side motion) and roll (banking motion) axes of an aircraft. This is sometimes called yaw and roll coupling. When a jet or commercial airliner, like a Boeing 737 MAX, experiences this instability, it may begin to oscillate. These … Read more

Windsocks in Aviation: Speed & Direction

The visual guide above shows how a windsock’s angle and extension help pilots estimate wind speed and direction during flight operations, enhancing safety on the runway. In this article, I’ll define them, explain their meaning, and explore their installation, calibration. They plan an essential role in preflight checks and runway wind condition assessments. What is a windsock? Every airport, whether a small rural airstrip like Massey Ranch Airpark or a busy international hub like Orlando International Airport, features one key visual tool for pilots: the windsock. These simple-looking devices play a critical role in flight safety by serving as aerodrome wind indicators. A windsock, also called a wind direction indicator, is a cone-shaped fabric tube mounted on a pole that … Read more

Understanding Aviation Fuel: Types, Uses, and Safety

Aviation fuel powers the world’s aircraft, supporting countless commercial, general, and military flights each year. From jet fuel to avgas, this vital resource comes in various grades and compositions, each with specific performance characteristics. In this article, I’ll explore what aviation fuel is, how it’s used, safety issues, and the future of sustainable aviation fuel (SAF). What is Aviation Fuel? What Aviation fuel refers to any fuel used to power airplanes or aeroplanes, primarily Jet A/Jet A-1, Jet B, and aviation gasoline (avgas). The chemical formula, composition, autoignition temperature, and flash point vary depending on the type. These properties are key to ensuring safe engine performance under extreme conditions. Types of Aviation Fuel Compared Different types of fuel are used … Read more

Understanding Ailerons: What are they and how do they work?

Ailerons are essential flight control surfaces mounted on the trailing edges of an airplane’s wings. Their primary function is to control the aircraft’s movement along the roll axis, which allows the aircraft to bank left or right. Whether flying a Cessna Skyhawk here at Epic or a Boeing 737 for the airlines, understanding how they work is fundamental to aircraft operation and maintenance. What do ailerons do? The function of ailerons is to manage roll control by creating differential lift on each wing. When the right aileron deflects downward and the left aileron upward, the airplane rolls to the left, and vice versa. This movement is coordinated through cables or other mechanical linkages in the flight control system. How do … Read more

Understanding Indicated Airspeed: A Pilot’s Guide

Learning to fly a plane, whether a light aircraft like a Cessna 172 here at Epic or a Boeing 747 jet, involves mastering many cockpit instruments. However, none is more essential than the Airspeed Indicator (ASI). Indicated Airspeed (IAS) is a fundamental concept in pilot training because it helps pilots measure and manage flight performance, lift-to-drag ratio, and safety-critical V-speeds. Here, I’ll get into IAS, explain how it works, define related airspeed types, and show you how to read and correct airspeed for better accuracy. Let’s get started! What is indicated airspeed (IAS)? A good definition for indicated airspeed is the speed shown directly on the aircraft’s ASI without correction for instrument errors, altitude, or air density. It reflects the … Read more
