Real World C172 Pilot Feedback on issues with the Asobo C172

I’m a commercial certificated pilot that attended Embry-Riddle Aeronautical University that has over 200 hours of flight time in the G1000 C172S alone. There are 8 major issues with the Asobo C172 that have caught my attention in the last 4 years. These issues apply to both 2020 and 2024. If these issues can be fixed, this plane will be really accurate to real life.

Description of the issue:

  1. Wrong startup RPM speed: In real life, the start procedure is to add 1/4 inch of throttle. This gives you about 1000-1200 rpm. In the sim when you look down at the throttle and apply 1/4 inch and start the engine, the engine goes to 630rpm, not anywhere close to the 1000-1200rpm like in real life.
  2. Idle speed is too low: In real life, idle speed should be above 650 rpm (this is what you check for on the runup). Its very rare for it to be below 650, its usually anywhere from 670-710 rpm.
  3. Yoke trim switch sound: In real life, even without wearing a headset you can’t hear the trim switch on the yoke move. In the sim its very loud and you can hear it.
  4. Aerodynamics on takeoff: This might be an Asobo issue with the aerodynamics model, but in real life, when you do a soft-field takeoff, the nose wants to rise almost immediately after you apply full power (probably at around 10-15kts). In the sim the nose of the plane only lifts at about 40kts.
  5. Avionics light adjustment: In real life, even if the PFD and MFD screen brightness is set to auto, you can adjust the screen brightness with the avionics rotating knob. In the sim the avionics rotating knob doesn’t change the brightness of the screens at all.
  6. Back panel white lighting gets too bright on max brightness: At night when I set the back panel brightness to max, its way too bright compared to real life.
  7. Stby altimeter vs PFD: In real life, you control the PFD and stby altimeter setting separately. In the sim, for some reason these are connected. Not sure if I can disable this, if not then its definitely a bug.
  8. Yoke movement: Just like many other planes in the sim, the last 20-25% of the yoke’s movement in a specific axis causes the yoke to move so much. It does not match the movement of the elevator or ailerons visually on the plane. If I turn my hardware yoke 70 degrees, in the sim its about 40 degrees, but when I move my yoke to >80 degrees, the yoke moves from 40 degrees to 70-80 degrees in the sim. I think you know what I mean.

Provide extra information to complete the original description of the issue:
• IRL C172 Pilot here. 100% agree on those points.
• One extra point: It is only me or rudder input needed during takeoff is totally reversed? . In a zero wind day, the FS C172 requires left rudder to maintain it centered in the takeoff run while in real life, you need to input right rudder!

Thanks for this real comparison, hopefully Asobo will take this into account and fix these issues to provide us more realistic enviroment since 172 is one of the most important GA planes :crossed_fingers:

Thanks for the informations :+1:.
Let’s not forget the bug of the fuel tanks on the C172 which only reaches 95% and never 100%! what are the 5% missing? water???

The only way to get 100% is to buy a plane for missions in FS2024, which comes with a full tank. Otherwise, when you fill the tanks, you never get above 95%. And that’s how it’s been for five years!

Yes, that is another major issue that I forgot to add.

Maybe its because 5% is unusable fuel. Irl the C172 holds 56 gallons total, but 53 gallons is usable. 3 gallons is unusable (combined from each wing).

53/56 rounds to 95%. Very impressive if this is why its 95% in the sim. However, the fuel weight should equal 56 gallons. A gallon of 100ll is 6lbs. Gotta do the math to see if the plane simulates usable and unusable or just usable.

Just pointing out that this might not be a bug after all.

Question: aren’t the Cessnas, 152 and 172 in this case, able to do (maybe very) tight turns on the ground? Because as it is currently, I have to push full rudder to either side to enter or vacate the runway, same when turning to parking or to a perpendicular taxiway.

I think they’d need to make the 172 (and 152) turn sharper according to what I’ve heard other real life 172 pilots say and post.

They turn sharply (on the inside wheel) if you use differential breaking as well as full rudder.

That’s what I’ve done with the Asobo C172, but I thought this was wrong because of the WB-Sim 172 mod (and JP Logistics C152 mod) which can do VERY sharp turns without differential braking.

I’m a happy camper then.

For 8. Yoke position – you can adjust your sensitives, either in game (although the capabilities there are poor in 2024) or possibly with your hardware drivers.

14

Yes, but I’m talking about the physical appearance of the movement of the yoke in the sim. Feel wise, its great, but what I do on my yoke does not look the same in the sim.

15

Also have many rw hours in G1000 172s.

100% correct on point 1 - the physical position of the throttle to meet certain RPMs is way off. Mixture as well, tbh. To illustrate the difference, I was flying the Comanche last night, which responds correctly. To start it, I unwittingly had about the same physical amount of throttle in as I use for the sim 172, and it zoomed up to about 1500 RPM on start, much like the real world versions of the Comanche and 172 would.

  1. Agree - it would run really rough at those low idle settings, feel like it’s missing and about to cut off. You’d probably also be getting a lot of voltage and oil pressure CAS messages.

  2. NA for me as the 172s I fly aren’t so equipped

  3. Soft field is always weird in the sim, for every plane. It’s very difficult to replicate well without the correct tactile feedback on the yoke (especially with regard to increased airflow), peripheral vision, and the feel of the wheels leaving the ground. I agree that it’s a bit less responsive, but sometimes I feel like it is actually too easy to over-rotate. Will have to do some more testing while looking at speed.

  4. Yep. Dimming is also a good way to stop students from fixating on instruments during visual maneuvers

  5. I haven’t played with this to notice

  6. Yes, they’re attached to the same sim var. they need to be separate - that’s just a poor implementation for this individual aircraft. Other planes can do this correctly.

  7. This is a frequent issue with a lot of planes and it’s going to vary depending on the range of your yoke as well. I don’t put a lot of stock in it.

I’d also add that there are some key functions missing from the G1000, but that’s a different thread.
