PMDG Releases the 777-300ER for Microsoft Flight Simulator

The most hotly anticipated aircraft this year has been released for Microsoft Flight Simulator. The PMDG 777-300ER for MSFS is now available to download and install. Now you will be able to fly one of the largest modern aircraft in MSFS and conduct a range of long-haul flights.

The 777-300ER is the largest of the currently flying Boeing aircraft in the 777 family (the 777X doesn’t count…yet) and serves airlines around the world. You can perform shorter intercontinental flights or ultra long hauls in the twin-engine jet. It uses modern technology including fly-by-wire functionality and plenty of automation to make the flying experience for passengers and pilots a joy.

The feature list for this aircraft is absolutely massive. Beginning with the modelling, you will find a highly detailed rendition of the 777-300ER, complete with physics-based wing flex for a realistic look. Textures are high quality, with attention given to all areas of the cockpit, external model and even the passenger cabin. Cockpit lighting is also highly realistic and provides an ambience.

All avionics and system management for the 777 have been modelled, including accurate display, screen mapping, data presence and more. The air conditioning, hydraulics and electrical systems are all custom made, react realistically to situations and all dynamic to your flight. The fly-by-wire functions of the plane are also fully modelled and present.

Engine data has also been correctly applied in both normal and abnormal circumstances. This also includes a custom and realistic autothrottle function that behaves according to real-world spec.

Failures are also modelled with the plane, meaning you can give yourself the ultimate test. They will either work randomly, activate on a fixed time, or be the result of mishandling or based on approximately realistic rates of failures in normal flying.

PMDG has also included its own range of features add additional functionality to simmers. The PMDG universal tablet is included on day-one of the release, and is able to be positioned in a number of places in your aircraft (or ‘in hand’). The Universal Flight Tablet allows you to link to SimBrief and Navigraph, do performance calculations or call up the ground service vehicles for your aircraft. A new turnaround mode also syncs with GSX to work seamlessly. Time compression returns, meaning you can do long-haul flights in just a fraction of the time.

One area that is brand new is the Datalink services. For example, you will be able to request departure clearance, grab Oceanic clearance, get the latest ATIS information, and much more. This requires the HOPPIE network, but functionality can and will be expanded even more in the future.

There is much more, but you can read it all in the feature list down below.

You can buy the PMDG 777-300ER right now from the PMDG store for $77.73. It will come to Marketplace in the near future for PC and Xbox.

  • The entire AFDS system is modeled in detail, including the C*U logic that allows the fly-by-wire system to closely mimic the feel of a conventional airplane while washing out the bad habits of older-generation airliners, such as pitch-coupling related to thrust changes.  This system makes the 777 such a marvelously stable platform to fly, as the fly-by-wire logic helps improve both speed and pitch stability while retaining the conventional pilot input-response mechanism common to nearly all other aircraft that a pilot may have flown.
  • The ground spoilers only deploy partially until the aircraft deck angle is reduced, at which point they are allowed to deploy fully. You can see this behavior in many YouTube videos and on your PMDG 777.
