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.

EASA 147 Aviation School - Personnel Requirements

EASA 147 documents for an approved maintenance school has identified the following groups of personnel to be made available:

- An Accountable Manager

- Knowledge Instructors

- Practical Instructors

- Assessors

The requirements for the above groups are as follows..

a. Management - The Accountable Manager

EASA 147 views the role of accountable manager as very critical. He has to display understanding of the 147 requirements and to ensure that the resources, processes and procedures are implemented to support the stated requirements.

A person had to be appointed to ensure that the company comply to the requirements of the 147 requirements.

b. Requirements for Knowledge Instructors

The initial course to be done under the guidance of an approved instructor.

Getting English Instructor

The ICAO requirement is very clear on the education requirement to become an aircraft engineer. It is the ability to read and write English.

I can imagine the difficulty faced by the peoples involved in drafting the requirements, as it had to satisfy the 100 over countries. If I were a British, I may like to put the "O" as the minimum requirement, but that may be accepted by the Russian or even the France. So to be safe, no education requirements were put. However each of the country can insert his own requirements.

In our school for aircraft maintenance in Malaysia, English is a core subject. It becomes necessary as english is not the mother tongue and neither it is the language in the education system. So most of the students are not able to express themselves and the understanding of the technical instruction is limited.

The teaching of English is given in the first semester. The total of 400 hours is dedicated to the subject. This is enough to give the student the skill and the confidence to communicate. This is important as the new EASA system is done in the modular format, as the first module, mathematics is conducted in a short period of 3 weeks, then the students will sit for the first module.
