How to Calculate the number of Trainers Required

The trainers are the most important resource to run a school. I am sharing the formula that can be used to forecast the requirements of trainers required. However, always bear in mind that this is only a forecast and there is always room for error.

There are a few assumptions we have to made. The forecasted may change if the assumption changes. The assumptions are:

a. The class hour per group is 2400 hour for a period of 4 years. (Note: Part 66 EASA states that the training hours is 2400 hr minimum and 40% can be practical.

b. The course of study is 4 years.

c. Instructors teaching hours is 70 hours per month

A. The calculation of the number of instructors:.

If you have 4 intakes per year, and your current number of class is 6, then in one years time you will have 10 classes.

- 10 classes will require 10x2400 hours for 4 years.

- therefore the hour per year = 10x2400/4 hours

= 6000 hours per year

- therefore nbr of instructors = 6000/12 divided by 70

= 7.1 instructors

B. The situation get more complex if the trainers are specialized. Some can only teach airframe, some can do engine and others probably electric. The calculation requires dividing the contents into separate trade.
