RRF or Real Random Failure is an addon for flight simulator that randomly invoke aircraft's failure behind the scenes without you knowing it

In my own simulation world, I currently fly PMDG 737-800 for Westjet, an airliner based in Canada. In my simulation world, I divided airlines into three tiers, namely tier 1, tier 2 and tier 3 (T1, T2, T3). Basically, this divides airlines based on their operational quality and perception. Based on this over simplified indicator, I categorize Westjet into tier 2 (T2) due to its Skytrax rating of 3 stars (WestJet Airlines is certified as a 3-Star Airline | Skytrax).

Next, on the other side of the dimension, I categorize the specific aircraft (since I only fly one single aircraft per airline in my simulation world) based on its "mileage" / accumulated flight hours into five (5) tiers i.e. >200 hours, 150-199 hours, 100-149 hours, 50-99 hours and 0-49 hours. And these tiers are furthermore categorized into A-check, B-check and C-check categorizations.

In real aircraft maintenance concept, aircrafts are undergoing major maintenance called A-check, B-check, C-check and so on. Aircraft maintenance checks - Wikipedia

What all of this mean is the probability of a failure could happen is entirely determined based on these factors:

• Airline operational quality. The better quality the better maintenance service and records it has

• The "mileage" / accumulated flight hours. The more aging an aircraft has the more it is prone to failure due to wear and tear effects.

In PMDG 737, you can always refer to the "mileage" value on the CDU. TODO: show it

In my simulation world, my airline Westjet, is in T2 and the aircraft is now currently 87 flying hours remaining before having undergo B-check maintenance soon. See the purple bold highlighted in the screenshot above, that is where it's being categorized presently. Take note on the value of the purple bold highlighted in the table, the value is 1/31. This means, a failure will be probable to happen 1 in 31 flights. This is the exact configuration needs to be created in RRF.

In RRF, having the probability of 1/30 for example, does NOT necessarily mean failure will happen exactly 1 in 30 flights. It could happen slightly more than 1 or not at all, but the probability is there and will be well represented in reality. Buckle up and expect the surprise.
