Every time you load the Fenix, it is brand new. No wear. No history. No consequences.

Fenix TechLog changes that. It gives each airframe a memory: a tech log, an MEL, part wear and a flight log that carry on from one session to the next. When something gives out, or you abuse the aircraft, the failure is set in Fenix within seconds, in flight too. You fly the ECAM and QRH, land, then fix it or defer it on the tablet against a real-world date.

For the Fenix A319, A320 and A321 in Microsoft Flight Simulator 2024. Free.

What it does

1. Persistent aircraft. Open and deferred defects are set in Fenix again at the start of every session. Fuel from the last shutdown is put back when you load cold and dark. Oil, oxygen, water, tyre pressures, brake and tyre wear, hours and cycles all carry on. One record per registration.
2. Failures with a cause, not dice. About 150 part types are tracked, each with its own life from the moment it is fitted. The same flights on the same aircraft always end the same way. Worn parts show a degraded fault first, then fail when they work hardest: on an engine start, at takeoff thrust, when the gear is selected.
3. Damage the moment it happens. Hard landings, flap and gear overspeeds, tail strikes, hot brakes, tyre speed, takeoff thrust held too long, engines shut down hot. Each leaves its item in the tech log, and the worse ones show on the ECAM straight away.
4. Tech log with an MEL. 207 items with categories, placards and restrictions. NO-GO items ground the aircraft. The others can be deferred to a real date (category B 3 days, C 10 days, D 120 days) and are fixed on that day.
5. MEL look-up by ECAM alert. Type the alert as the ECAM shows it, for example ELEC GEN 1 FAULT, and get the item: whether the aircraft may go, under which conditions, and what the crew does in each phase of flight.
6. Landing distance with your defects. TechLog asks Fenix's own calculator, with the failures in your tech log already selected, and shows the distance with and without them against the runway length.
7. Fix it, or replace it. Worn parts are listed on the Service page. Fix repairs the part that is fitted and gives some of its life back, less each time. Replace fits a new one.
8. Used airframes. Start with an aircraft that is several years old. It arrives with a few items deferred under the MEL, cabin items waiting for parts, and the small findings every aircraft in service carries.
9. Every flight recorded. Touchdown rate, G and speed, the touchdown point on the runway, approach stability at 1,000 and 500 ft, a timeline of what happened, the systems affected, the wear the flight used, and a score.
10. The whole cabin. Every seat, galley and lavatory wears: tray tables, seat belts, reading lights, ovens, coffee makers. A broken belt blocks the seat.

Updating: run the new setup. It installs over the old one and keeps your airframes and flights. Removing: Windows Settings → Apps → Fenix TechLog → Uninstall.

Good to know

1. The first time a registration is loaded, TechLog creates a brand-new airframe for it. For a worn one, open Settings before the first flight and make it a used airframe of the age you want.
2. If you only want failures that come from wear and from how you fly, turn Fenix's own random failures off in the Fenix EFB. With them on, TechLog still logs and keeps whatever Fenix fails.
3. Maintenance can be instant, or take its real hours while the aircraft stays parked. Wear rates can be turned up or down. Both are in Settings.
4. The MEL text is TechLog's own, written for simulation. Never use it for a real aircraft.
