SU4 Beta has introduced a wide variety of price changes and new aircraft for career mode which changes the best planes for your passive income fleet. All you need to know is in the data I have displayed here and the explanations I have provided below.
Lets review the information here
Highest earning aircraft per hour:
- 737 MAX (718,432 per hour)
- Viking Air CL-415 (370,164 per hour)
- Erickson Incorporated S-64 (258,065 per hour)
Bear in mind these aircraft are also the most expensive in the game and are not necessarily the most efficient.
Lowest payback time aircraft:
- Cessna C400 Corvalis TT (46 hours)
- Patey Aviation Draco X (46 hours)
- Cessna 172 Skyhawk (46 hours)
These aircraft are able to earn what they cost to buy the most quickly and are a good choice for the early stages of career mode. Bear in mind that there is no formal feature for streamlined maintenance yet so it would be unrealistic to stack up 100’s of these aircraft even though they are the most efficient since aircraft stop producing passive income after wear becomes too much.
Aircraft that seem good at face value but are actually bad on further inspection:
- 737 Max (biggest earner per hour but also lowest payback time aircraft)
- Zillin Aviation Savage Cub (looks cheap and earns decently but is less efficient than more expensive aircraft)
- Cessna 208B Grand Caravan (looks like a plane that is a balance of both worlds - income per hour and efficiency - but underperforms compared to other expensive aircraft)
Aircraft that seem bad but are actually quite good
- Daher TBM 390 (Expensive but payback time is very low and is good since you will have less aircraft to maintain manually)
- Diamond DA62 (More expensive for only a slight increase in payback time)
- Textron Aviation Cessna Citation CJ4 (A personal pick but a jet aircraft with a still high but not very high payback time, combined with the fact you will be maintaining aircraft manually this is a good pick for someone who wants to be making 100 million + per day in passive income, this aircraft used to cost 4 times more in SU3 so it has become a more viable aircraft)
Personal view on how to build a worldwide fleet:
Step 1: Buy a company, for example a flightseeing or light cargo would be a good choice.
Step 2: Grind your own missions (using lowest payback time aircraft) in combination with earning passive income.
Step 3: Gradually build your fleet and purchase a VIP transport company where you can purchase a fleet of aircraft, I would suggest a quite expensive fleet, sacrificing efficiency for manageability of maintenance in the long run, for example the CJ4 or Diamond DA62.
Step 4: Once you are earning more than 200+ million per day purchase a passenger transport and switch your strategy to purchasing 737’s for a worldwide fleet (if that’s what you want) and gradually build your fleet keeping non 737’s to cover maintenance.
Until MSFS adds a streamlined maintenance feature for the game (especially on Xbox where you can’t get mods) this is in my view the best way to realistically grow your worldwide empire of aircraft.
This data may change since this is still a “Beta” version
