CFI Brief: Aviation Weather Services (AC 00-45H) – UPDATE

The FAA has issued a Change 1 to Advisory Circular AC 00-45H effective January 8th 2018. AC 00-45, more commonly referred as Aviation Weather Services, is the go-to resource for U.S. aviation weather products and services. This document is organized using the FAA’s three distinct types of aviation weather information: observations, analyses, and forecasts. This […]

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 […]

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. […]

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. […]

CFI Brief: The ASA CX-3 Flight Computer—Coming REAL soon!

You have been asking us for an aviation flight computer with a backlit display, and trust us we’ve been listening. But we thought, if we are going to design a flight computer with a backlit display, why stop there? Wouldn’t it be cool if we had a backlit keypad as well? It sure would, so […]

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 […]
