Real Random Failure (RRF)

Addon for MSFS 2020 & MSFS 2024

This addon will help you randomize the possible failures to your aircraft without you knowing it.

This addon is for:

  • MSFS 2020 - PMDG 737 - stable BETA
  • MSFS 2024 - PMDG 737 (coming soon)
  • PMDG 777 (MSFS 2020 & 2024) (coming soon)
  • generic MSFS failure (in the pipeline)
  • Other addon aircraft that deemed feasible (in the pipeline)

Scenario 1: Random Failures for A to B Flight (Actual flight with passengers)

Imagine, you are going to fly your aircraft from point A to point B. When you know nothing (i.e. failure) is ever going to happen to your aircraft, this is not an immersive experience.

Imagine, on the other side, when you use and arm the built-in random failures, you will know for sure that there will be a failure waiting to happen in your flight, it's just you don't know which minutes it's going to happen. This is too, not an immersive experience

RRF tries to settle in the middle ground for these both dilemas for better immersion. That is, naturally you fly your aircraft as usual but this time, RRF will handle the randomize event without you knowing it. Your aircraft could or could not have any failure, you don't know. And you as the pilot, you are not flying a failure-free flight, so you will always have the sense of uncertainty and you will always watch out and ready for the unexpected

Keep that QRH manual book handy, just in case!


Scenario 2: Random Failure and Timing for Simulator Line Check

Imagine, you are doing the bi-annually simulator check with your virtual Line Check Examiner (it's you yourself). You want to test yourself in certain (either specific or within categories of failure) emergency simulation. However you need set which failures or categories of failures by yourself and you need to set the timing of when the failure is exactly going to happen. Even you know, as part of the test in the simulator check, failure is surely going to happen, but knowing which failure is going to happen and the exact time when it's going to happen is killing the immersion. Here, RRF can be very useful. With RRF, you have no idea which specific failiure or which specific minute the emergency will start to happen.

Expect the unexpected!


Scenario 3: Random Inoperative System & Equipment

Real aircraft operation is not 100% problem-free. There are times that some of the aircraft system and equipment are inoperative during the start of a flight. It depends on the aircraft and carrier SOP whether or not the Pilot in Command may continue with flight. RRF may help you randomize that chances without you knowing it

Time to get your Minimum Equipment List (MEL) ready!

Bonus Tool! Cockpit Pager

A tool to notify you when there is a failure in your cockpit

You probably won't stick in front of the monitor every minutes in your multi-hours flight will you?. Now with the flight full of uncertainty, we understand that you will need this tool, because like any other flight simmers, while the plane is cruising, you will be doing something else and prabably somewhere else.

You will receive instant push notification to your mobile phone whenever there is failure is happening at the cockpit. Some of the failures/events can be notified to your phone:

  • Autopilot disconnected
  • Autothrottle disconnected
  • Fire alarm
  • Master caution illuminated
  • Master caution illuminated for specific reasons like electrical, hydraulics, fuel etc
  • Other warnings or failures

Key Features

These are some useful features of RRF.

Multiple Random Failure Profiles

You may want to create multiple random failure profiles, e.g. one profile for brand new aircraft that is more reliable with less probable of failure, another one maybe for another aircraft which has clocked 500 hours of use, which is relatively more proned to failures. Another profile for your ETOPS simulator check which could trigger either one of these: engine failure (left or right), APU fire, engine fire (left or right), cabin pressure emergency etc. Before each flight, just choose any of these profiles to activate

Set your own probability

For each profile, you set the profile's own probability, how likely a failure or emergency event to happen or not for each flight. Configure something like for example, "I want the chances for failure to happen 1 in 50 flights" i.e. 1/50 probability. Once configured, it might or might not happen. You won't know. If it is destined to happen, the addon will randomly choose which failure to occur (based on the selected profile settings), again you won't know until it happens

Integrate with Simbrief

Integrate with Simbrief to quickly input the flight time to be part of the calculation of the randomized time for the failure to happen (if it happens)
