CFI Brief: What a Drag!

Drag as it relates to aerodynamics in aviation is just one of those things that must be dealt with and overcome – literally  overcome. When we talk about drag in aviation it is usually discussed in relation to one of the four forces: lift, weight, thrust, and drag. It is the force that acts opposite […]

Aerodynamics: Forces in Climbs and Descents

We’re talking about aerodynamics again this week. Today, an excerpt from the Pilot’s Handbook of Aeronautical Knowledge on the forces in climbs and descents. Forces in Climbs For all practical purposes, the wing’s lift in a steady state normal climb is the same as it is in a steady level flight at the same airspeed. […]

CFI Brief: Angle of Attack as it relates to the Lift Coefficient

Monday’s post contained an excerpt from the Pilot’s Handbook of Aeronautical Knowledge discussing newly outlined content in regards to Angle of Attack indicators. What I hope you were able to gain from reading the earlier post was the correlation between Angle of Attack and a stall. The Dictionary of Aeronautical Terms defines angle of attack […]

Aerodynamics: Propeller Basics

Back to basics today on the Learn to Fly Blog: your propeller. The aircraft propeller consists of two or more blades and a central hub to which the blades are attached. Each blade of an aircraft propeller is essentially a rotating wing, and thus the blades act like airfoils producing thrust. Today’s post comes from […]

CFI Brief: Torque

Today’s discussion is on torque. An airplane of standard configuration has an insistent tendency to turn to the left. This tendency is called torque, and is a combination of four forces: reactive force, spiraling slipstream, gyroscopic precession, and P-factor. Reactive force is based on Newton’s Law of action and reaction. A propeller rotating in a […]

CFI Brief: Parasite and Induced Drag

Monday’s post touched on the topic of aerodynamics, specifically drag. As you can imagine, drag is an extremely crucial part of flying and also one of the four forces acting on an aircraft in flight (Thrust, Drag, Weight, Lift). Today I want to briefly cover and test your knowledge on the two types of drag: […]

Aerodynamics: Drag

This week on the Learn to Fly Blog we’re talking about drag. One of the four forces of flight, drag opposes thrust and at rearward parallel to the relative wind. We’ll get more into the practical application of your understanding of drag on Thursday with our CFI, but today we will define the two types […]

CFI Brief: Velocity vs. G-loads Diagram

Using the knowledge you learned from Monday’s post on the Vg diagram, let’s see if we can answer some of these sample FAA knowledge test questions. Remember, a complete database of sample questions can be found in ASA Test Prep Books and Prepware Software! Reference the figure below for all questions, however please note on […]

Aerodynamics: Vg Diagram

The flight operating strength of an aircraft is presented on a graph whose vertical scale is based on load factor. The diagram is called a Vg diagram—velocity versus G loads or load factor. Each aircraft has it’s own Vg diagram which is valid at a certain weight and altitude. The curved lines representing maximum lift […]

CFI Brief: Ground Effect, Pop Quiz!

I sure hope you read Monday’s post on ground effect because today I’m throwing a pop quiz at you! Remember that ground effect occurs when flying within one wingspan or less above the surface. The airflow around the wing and wing tip is modified and the resulting pattern reduces the downwash which reduces the induced […]
