CFI Brief: Icing

Ice sucks, unless of course you are a hockey player, figure skater, or just want a nice, cold, tasty beverage. But in terms of aviation, ice sucks. In general, icing is any deposit of ice forming on an object. In aviation icing is considered to be one of the major weather hazards affecting flight. We […]

Weather: Fronts

Today, we’re featuring an excerpt from Bob Gardner’s The Complete Private Pilot. A weather front exists where air masses with different properties meet. The terms “warm” and “cold” are relative: 30°F air is warmer than 10°F air, but that “warm” air doesn’t call for bathing suits. Cold air is more dense than warm air, so […]

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: FAA Safety Briefing, January 2018

The first edition of the FAA Safety Briefing for 2018 is now available and includes some great articles. One in particular that I found to be very informative is “Simple?” written by Susan Parsons. This is a great article that discusses getting back to the basics of piloting in an otherwise complex environment. To read […]

CFI Brief: CX-3 Flight Computer – Indicated Airspeed

Some questions on the FAA Knowledge Exam will require you to determine approximate indicated airspeed. These types of problems are best solved with the use of a CX-3 Flight Computer. Today, we will work through a sample knowledge test question requiring us to run several different calculations on the CX-3 to determine indicated airspeed from […]

CFI Brief: Pressure Altitude Conversions

Pressure altitude is the height above the standard datum plane (SDP). The aircraft altimeter is essentially a sensitive barometer calibrated to indicate altitude in the standard atmosphere. If the altimeter is set for 29.92 “Hg SDP, the altitude indicated is the pressure altitude—the altitude in the standard atmosphere corresponding to the sensed pressure. The SDP […]

CFI Brief: Altimeter Pressure Errors

High to low look out below, low to high clear the sky! If you have never heard that saying before you are probably pretty confused right now. Let me help ease that confusion and explain that today we are discussing altimeter errors when flying in areas of changing atmospheric pressures. The discussion will revolve around […]

CFI Brief: Airport Rotating Beacon

Have you ever wondered how pilots are able to determine the location of an airport at night or in reduced visibility? Well the answer is actually very simple. At night, the location of an airport can be determined by the presence of an airport rotating beacon light like the one seen in the image below. […]
