Primary Flight Display (PFD) v.1

Please use the latest version of the PFD

Introduction

The Primary Flight Display (PFD) is a crucial piece of modern avionics that allows pilots to operate the aircraft efficiently.

I've strived to make my rendition as realistic as possible, however, due to certain game mechanics and necessary simplifications, it differs noticeably from its real-world counterparts.

Description

For the latest PFD version

The PFD consists of the following parts:

1. Attitude Display

The Attitude Indicator (Artificial Horizon) allows pilots to determine the aircraft's orientation in space, including its pitch, bank angle, and sideslip.

The bank angle scale has markings at 10, 20, 30, and 45 degrees in each direction. If the bank angle exceeds 35 degrees (by default), the indicator turns yellow and becomes filled. At maximum sideslip, the slip indicator becomes fully filled.

2. Airspeed Display

The Airspeed Indicator is located on the left side of the PFD and displays the aircraft's current Indicated Airspeed (IAS) in knots. Additionally, it shows the speed the aircraft will reach in 5 seconds (by default) – the Speed Trend Vector – as well as target, maximum, and minimum speeds, and the ground speed / Mach number.

The maximum and minimum airspeed values are only displayed during flight. When the Mach number exceeds 0.4, the ground speed readout is replaced by the current Mach value.

The displayed airspeed range is from 20 to 980 knots.

3. Altitude and Vertical Speed Displays

The Altitude and Vertical Speed indicators are located on the right side of the PFD.

The Altitude Indicator displays the current altitude in feet above sea level, the target altitude, and the radio altimeter height, which is shown when flying within 2000 feet of the ground.

The Vertical Speed Indicator shows the aircraft's rate of climb or descent in feet per minute. The digital vertical speed value does not appear when the rate is below 400 feet per minute.

The displayed altitude range is from 0 to 90,000 feet.

The displayed vertical speed range is from 0 to ±6,000 feet per minute.

4. Heading Display

The Heading Indicator displays the aircraft's current and target heading.

5. UI

The Flight Mode Indicator is an interactive element consisting of three indicator buttons:

The left "SPD" button allows you to set the target airspeed and enable its display on the Airspeed Indicator.

The right "ALT" button allows you to set the target altitude and enable its display on the Altitude Indicator.

The center "T/NAV" button allows you to enable the Target Navigation mode.

The T/NAV mode is a conditional in-game navigation aid that helps the player fly towards a target in a director (semi-automatic) mode.

Select a target (whether it's a craft or a location) and press the button. To fly towards the selected target, you need to align the purple cross on the Airplane Indicator.

6. Warnings

The PFD features two warnings: PULL UP and STALL. Each has its own aural alert and can only be activated during flight.

The PULL UP warning is triggered if the aircraft is predicted to impact the ground within 8 seconds (by default). This warning takes priority over the STALL warning.

The STALL warning is activated when the aircraft's airspeed falls below the minimum level.

Usage and Customization

All aircraft are different – from small, slow crop-dusters to large, fast airliners. Therefore, the PFD program is designed for customization.

To begin, place the display in the desired location on your craft, then use the Width and Height sliders to adjust its size.

Then, open the display's program and adjust the parameters shown in the image below to fit your needs.

Feel free to use this PFD in your own creations! I would be happy to receive your feedback.

P.S. This PFD is planned to receive updates from time to time, so please make sure to use the latest version, which can be found at the link at the beginning.
