Primary Flight Instruments

Primary flight instruments provide essential information about an aircraft’s motion, orientation, altitude, speed, and climb/descent. They are fundamental to flight mechanics, pilot decision-making, and aircraft control.

Aircraft configurations

Aircraft configurations

 The primary components of an aircraft include the fuselage (body), wings (which produce lift), tail assembly (responsible for stability), powerplant (engine, which generates thrust), and landing gear (for ground support), all managed from the cockpit through flight control surfaces such as ail...

Lighter-than-air (Aerostats)

Lighter-than-air systems are the flight systems deriving a significant amount of their lift from the buoyancy effects related to lighter than air gases like hydrogen, helium and methane. Contrary to fixed-wing aircrafts LTA systems are associated with minuscule fuel consu...

    Compressible Flow

    Before using the calculator, ensure availability of the following parameters:

    1. Temperature, T (Kelvin, K)

    2. Pressure, p (Pascal, Pa)

    3. Velocity, V (meters per second, m/s)

    4. Gas Constant, R (J/kg·K)

    5. Ratio of Specific Heats, γ

      After calculation, the following outputs will be displayed:

      1. Density (ρ...

  • Geometric Angle of Attack (α): The angle between the chord line and the common reference line (often the horizontal axis of the aircraft).

  • Induced Angle of Attack (α_i): The angle by which the local airflow is deflected (downwash) compared to the free-stream velocity.

  • Abs...

    Basic Fluid Mechanics



    As I went on, still gaining velocity, the palpitation of night and day merged into one continuous greyness; the sky took on a wonderful deepness of blue, a splendid luminous color like that of early ...
