747 Classic development update - July 2020

Digital TAT/EPRL indicator, Autoflight panel and more!
28 July 2020

The 747-100 and -200 underwent many upgrades during their time in commercial service around the world. It’s always tough to choose between them all but our models are mostly based on the original configuration. We have, however, incorporated various upgrades that you have requested into our forthcoming 747 Classic add-on for P3D v4/v5.

As we near completion of the 747 Classic systems and avionics coding (no small task on this mighty and complex Jumbo!) we're continuing to improve the aircraft in direct response to community feedback and requests. We appreciate all the feedback we receive from our regular development updates, which often helps shape the ongoing development of our add-ons.

Here's an update on just some of the changes that we have made to the 747 during the past few months...

A digital TAT/EPRL indicator has been added to the centre instrument panel, replacing the analogue TAT indicator. This new indicator displays the total air temperature (TAT), selected thrust rating, EPR limit and mode, selected using the EPRL computer on the centre pedestal.

This computer allows you to select EPR limit modes for different flight regimes, such as take-off and climb, as well as derating modes. We have now added an improved autothrottle which can be used to hold a selected EPR and Mach, in addition to the original speed (IAS) mode. This additional automation eases the workload in this three-crew cockpit. Also visible here is the newer transponder and third INS unit for flights in modern skies with greater navigational accuracy and safety.

The transponder is connected to the early TCAS that we have fitted to the vertical speed indicators. These use a series of red and green lights to indicate how to resolve any TCAS conflicts.

One of the most recent additions are the two INS updating indicators which will indicate then the INS units are making use of the DME updating feature that we have simulated.

On the Autoflight panel, we have added a third autopilot channel allowing for additional redundancy, with dual or triple autoland capability. Perfect for low visibility operations!

New GPWS controls and indicators are also shown here. We have equipped the aircraft with a five-mode GPWS which will alert you to deviations from the ILS glideslope, high rates of descent and proximity to the ground when not properly configured for landing.

We have also fitted an upgraded Flight Mode Annunciator (FMA), shown above the altimeter in this image, which displays the modes selected on the improved autopilot and autothrottle.

A less obvious addition in the name of safety is a mirror fitted to the lower overhead panel. This is used by the Captain to confirm that the flap handle is in the UP position when the thrust levers would usually obscure his view.

TFDi will soon be releasing a P3D v5 compatibility update for RealLight and TrueGlass, and we have been continuing to improve the cockpit and exterior lighting effects. These images show the Flight Engineer’s backlit instruments and the taxi, landing and wing lights with realistic cones and ground illumination.
