Instrumentation is a crucial aspect of ATPL training, focusing on the instruments and systems that pilots use to navigate, control, and monitor an aircraft’s performance.
In an ATPL theory course, you delve into the intricacies of aircraft instrumentation, understanding how these systems contribute to safe and effective flight operations.
This is only meant as a guide to the Instrumentation subject as it applies to the Bristol Groundschool ATPL theory course.
Let’s take a closer look at some topics covered in the Bristol Groundschool ATPL Instrumentation course and some of the things you’ll learn about in each topic.
How basic mechanical instruments, pre-glass cockpit, work including:
Vertical speed indicators
Direction indicators and compasses
And the possible errors associated with these instruments.
For more modern aircraft, the working principles of:
Inertial reference systems
Flight management systems
Autopilots and autothrottles
Flight director systems
Head-up displays and synthetic vision systems
Datalink communications and ADS-B
Also, Instrumentation covers the principles of operation and the possible warnings associated with:
Airborne collision avoidance systems (ACAS)
Stall protection systems
Ground proximity and terrain awareness warning systems (GPWS and TAWS)
The exam for Instrumentation lasts 1 hour and 30 minutes. You’ll have 60 multiple-choice questions to answer during this time, with the pass rate being 75%.
