# Lesson 9: Flying Blind and Performance Calculations Pr Copy

## When you can’t see where you’re going:

Flying blind doesn’t sound so fun.  Although many pilots do fly airplanes through clouds and zero visibility conditions on a daily basis, it requires a lot of training and practice to have the proper knowledge and skills to do so safely.  Far too many pilots die each year due to flying into clouds or low visibility conditions and not having the proper skills to get out of the bad weather.  In this lesson we’ll show you some of what you’ll be doing in training to learn how to get out of those very conditions.

## How good of a performance can you expect?

When planning to takeoff, it is essential to do the proper planning to ensure that the aircraft will be within weight and balance limitations, not exceeding its gross takeoff weight, and know the performance calculations to determine exactly how much runway you will need for takeoff and landing, along with how much fuel you will burn and what altitude you will fly at.  These and more are essential calculations each pilot makes every time before they go fly.  In this lesson we’ll show you how to make some of the calculations by hand the “old school way” so you have a basic understanding.  In later lessons we’ll show you how to use an Ipad or other electronic flight planning apps to do the heavy math for you.
