Aerodynamics: Descent and Gliding Flight

Our CFI is out enjoying the Reno Air Races this week, so today we’ll share a follow up to Monday’s post with another excerpt from Aerodynamics for Aviators. Descending a light propeller-driven general aviation aircraft is a fairly simple task. Reduce power to a point where there is more power required than power available, and […]

Aerodynamics: Cruise Flight

Cruise flight centers on two basic principles: how far we can fly, and for how long. How far we can fly is defined as the aircraft’s range. How long we can fly is defined as endurance. Today’s post is an excerpt from our textbook Aerodynamics for Aviators. When flying, we generally consider range in two […]

CFI Brief: Caution for the wake turbulence from the departing 757

Today we are going to take a look at wake turbulence, which is the disturbed air left behind an airplane. Why you may ask is this important to us? This disturbed air left behind an aircraft can form tornado like vortices that are dangerous to all aircraft, particularly smaller general aviation aircraft operating behind a […]

Aerodynamics: Power

Today’s post is excerpted from the second edition of our textbook Aerodynamics for Aviators. This book features extensive illustrations and covers everything from the fundamentals of flight to high-speed flight, and includes an excellent compendium of formulae and equations used at all levels of aviation. Aircraft aerodynamics involves the interaction of the four forces: lift, […]

CFI Brief: Flight Controls of a typical Commercial Airliner

This week on the Learn to Fly Blog the theme has been aerodynamics, and rather than stick to Private Pilot level aeronautical information we’ve hit you with some “graduate level” knowledge. Today, I thought it would be interesting to take a look at the primary flight controls of a typical commercial airliner. Looking at the image […]

Aerodynamics: High Speed Flight

Today’s post comes from the Pilot’s Handbook of Aeronautical Knowledge (FAA-H-8083-25B). In subsonic aerodynamics, the theory of lift is based upon the forces generated on a body and a moving gas (air) in which it is immersed. At speeds of approximately 260 knots or less, air can be considered incompressible in that, at a fixed […]

Aerodynamics: The Spin

Today on LTFB, we’re featuring an excerpt from The Pilot’s Manual: Ground School (PM-2C) on spins. A spin is a condition of stalled flight in which the airplane follows a spiral descent path. As well as the airplane being in a stalled condition, and yawing, one wing is producing more lift than the other, which […]

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 […]
