Practice Approach into Sky Harbor

My colleague((and friend 😁)) Edward Abraham and I departed from California to Minnesota in N81034 to train for our CFI-I ratings.((You can read more about that trip in my upcoming post.)) We laid out a training program to test our CFI-I syllabus, including a day of practice instrument approaches.

These practice approaches were chosen for challenging variety, interesting destinations, and efficiency when stringing several together.

How to Convert Knots to MPH, and More Unit Magic
using conversion factors to change units and confirm results

The boring way to convert knots to mph is to multiply knots by 1.15.((This is actually more like 1.150779, but we’ll use the rounded version.)) But this skips over some awesome unit magic.

Specifically, we can use conversion factors to change between related units. Let’s look again at how to convert knots to mph.

Suppose you’re traveling at v\ \text{knots}=v\ \frac{\text{nautical miles}}{\text{hour}}. Then,

    \[ v\ \frac{\cancel{\text{nautical miles}}}{\text{hour}} * \frac{1.15\ \text{miles}}{1\ \cancel{\text{nautical miles}}} = v * 1.15\ \frac{\text{miles}}{\text{hour}}} = v * 1.15\ \text{mph} \]

Did You Just Cross Out the Units?

I did! This is called a conversion factor,((More precisely, you may hear this called dimensional analysis or the factor-label method.)) and is based on the principle that anything multiplied by 1 equals itself. It is an easy way to convert between units, and allows us to solve a variety of aviation problems.

10 Important Figures on the Instrument Knowledge Test
info about figures that are likely to appear and may be easy points

It turns out there is only a handful of figures on the instrument knowledge test that:

  1. Are likely to be asked about, and
  2. Could be easy points on the test.

These are the 10 figures I believe are worth a closer study.

Learn ForeFlight the Easy Way: With a Flight Simulator
a collection of simulator resources to build proficiency with ForeFlight

The best time to learn ForeFlight is on the ground. With a bit of practice, you can safely leverage its many features while flying. (And avoid figuring them out in the air!)

This post collects together several resources on how to connect and use ForeFlight with a flight simulator.
