Aircraft Systems: Fuel Injection Systems

Today we’re featuring an excerpt from The Pilot’s Manual: Ground School (PM-2C). Many sophisticated engines have fuel directly metered into the induction manifold and then into the cylinders without using a carburetor. This is known as fuel injection. A venturi system is still used to create the pressure differential. This is coupled to a fuel […]

CFI Brief: How does a Propeller Work?

The propeller is a rotating airfoil which produces thrust by creating a positive dynamic pressure, usually on the engine side. Some exceptions include the Piaggio Avanti, shown below which uses propellers mounted in what’s often referred to as the pusher configuration. When a propeller rotates, the tips travel at a greater speed than the hub. […]

Aircraft Systems: Propeller Principles

The propeller, the unit which must absorb the power output of the engine, has passed through many stages of development. Today we’ll feature an excerpt introducing the general concepts of a propeller from our recently released book Aircraft Systems for Pilots. Propeller Principles The aircraft propeller consists of two or more blades and a central […]

CFI Brief: It’s Getting Hot in Here.

Today, I would like to recap Monday’s post on the aircraft engine cooling system and go over some typical questions you will likely see on your FAA Private Pilot knowledge test. First off, we learned about the effects of operating with an excessively high aircraft engine temperature and that it can lead to loss of […]

Aircraft Systems: Engine Cooling Systems

Today’s post is excerpted from Pilot’s Handbook of Aeronautical Knowledge. The burning fuel within the cylinders produces intense heat, most of which is expelled through the exhaust system. Much of the remaining heat, however, must be removed, or at least dissipated, to prevent the engine from overheating. Otherwise, the extremely high engine temperatures can lead […]

Aircraft Systems: Types of Electricity

Today, we’re featuring an excerpt from our new textbook Practical Electricity for Aviation Maintenance Technicians. As you can tell from the title, this book is geared for new AMT candidates, but it does feature a wealth of information on aircraft electrical systems useful to anyone flying or fixing airplanes. There are two basic types of […]

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 […]

Aircraft Systems: Pressurized Aircraft

Aircraft are flown at high altitudes for two reasons. First, an aircraft flown at high altitude consumes less fuel for a given airspeed than it does for the same speed at a lower altitude because the aircraft is more efficient at a high altitude. Second, bad weather and turbulence may be avoided by flying in […]

CFI Brief: Cold Weather Operations

We are well into fall and winter seems to be fast approaching, I am ever reminded by all the holiday décor already up around town. For the majority of us, baring you lucky few down south, we will notice drops in temperature and for many areas across the United States temperatures can drop well below […]

Aircraft Systems: Fuel Contamination

Fuel contamination is a preventable event. Today, we’ll take a look at what the new edition of the Pilot’s Handbook of Aeronautical Knowledge has to say about it. Accidents attributed to powerplant failure from fuel contamination have often been traced to: Inadequate preflight inspection by the pilot Servicing aircraft with improperly filtered fuel from small tanks […]
