What is the Name for the Six Basic Aircraft Instruments?
For a pilot, the flight deck is the heart of their operations, where all decisions are made, and life or death depends on making accurate assessments and judgments. To help them achieve their mission, six primary flight instruments have been identified and are crucial to aviation. These six basic aircraft instruments, also known as "six-pack" instruments, provide vital information for a safe and efficient flight.

The Six Basic Aircraft Instruments
1. Altitude Indicator: The altimeter displays the current altitude of the aircraft, both above and below the destination or flight plan.
- The altimeter needle is a sensitive and intricate part that moves freely inside a scale ring
- It indicates the true airspeed (TAS), air density, and wind velocity to ensure a accurate reading
- Important information is shown, including maximum rate of climb (MR), ceiling (ceiling is the maximum height attainable without leaving a predetermined distance away), and normal maximum climb speed.
What happens when an Altimeter reading is inaccurate?
Inaccurate altitude readings can have catastrophic consequences, leading to accidents due to terrain following errors. If an altimeter fails or provides an incorrect reading, it may be corrected using GPS and Radar, and it’s also vital to regularly calibrate your altimeter.
2. Airspeed Indicator (AS)**:
Air Speed (A/S) shows the actual velocity of the aircraft. Two major aspects to this vital indicator include:
• Indicating speed below sound and above sound levels for V-Speed calculation, providing accurate decisions
• Alerting the pilot about flight parameters exceeding their assigned velocity range
Air speed measurement accuracy can impact engine health, safety, and pilot’s response during take-off and landing, requiring utmost precision
Why do you need accurate air speed data?
To stay airborne safely and to minimize wear and tear on engine, aircraft control surface durability
It plays crucial in navigating obstacles like buildings or obstacles near an airstrip, precise descent is more easily calculated with Air speed indicator data.
