Before revision: Traditional Format of Boeing 737 1.Airspeed indicator on the grey left bar (300) 2.Attitude indicator in the middle (blue and brown colored) 3.Altimeter on the grey right bar (30000) 4.Turn coordinator (shown by the white triangle and a white rectangle below “CMD” green text) 5.Heading indicator at the bottom centre (0°/360°) 6.Vertical speed indicator (grey trapezoid form on the right) Components While the PFD does not directly use the pitot-static system to physically display flight data, it still uses the system to make altitude, airspeed, vertical speed, and other measurements precisely using air pressure and barometric readings.
