Hey I was just wondering how you guys trim your aircraft? And what trim you usually use during take off, cruise, etc. Thank you!
I usually use 15% trim on all of my flights
Trim is quite hard to understand at first and this is a very fair question. Essentially it gives assitance to pilots during crucial stages of a flight such as climb, descent and cruising. The purpose of it is to replace the pressure of the primary controls, which makes it easier for pilots to maintain a stable altitude.
I will leave a very useful topic below. I highly recommend you check it out :)
Honestly I use trim according to This when taking off and landing but I will follow the pink recommended trims on the HUD during cruise
I’m sorry, I misread what you are asking. I generally use 5% trim on takeoff, 5%-10% trim at cruise, and 5% trim on landing. This however will vary depending on the aircraft I am flying.
10% the whole time?
No. It varies based on aircraft weight, winds, etc. I said 5%-10% as that is what I generally use.
Edit: Use what @lucaviness said to grasp a better understanding of what would suit you and your flight best :)
Hey! The amount of trim that one uses is really not a set number. It all depends on your aircraft, weight, winds, and other factors. Different stages of flight require different uses of trim. Here are a few examples:
- Takeoff
For takeoff, it is recommended to keep your trim pretty neutral or slightly positive. Upon takeoff, you’ll need to apply back pressure on the yoke to climb. As you increase your speed, the amount of back pressure in use decreases, and will eventually be neutral (cruise).
- Climb
After takeoff, wait to re-trim the aircraft until you’ve adjusted your climb configuration. Retracting the flaps will cause your plane to pitch up or down, and you’ll need to re-trim to keep the nose pitched for your desired climb.
- Cruise
The higher you get and the more you level off, you start accelerating. Set your cruise power setting and wait for your airspeed to stabilize. While your airspeed is stablaizing, you can start applying negative (nose-down) trim in small increments to keep your aircraft’s nose down and prevent furthur climbing. This requires some fine tuning, but once you’re trimmed to the perfect setting, you may let go of the yoke, and your plane won’t pitch up or down.
- Maneuvers
You should trim for every maneuver that you attempt. Use positive or negative trim to help keep your aircraft stable so that you don’t need to be applying a constant pressure on your yoke.
- Descent
Depending on your type of descent, you’ll either want to use positve or negative trim. If you are doing a powered descent, you’ll need nose-down trim in order to prevent the aircraft from wanting to climb again. If you do a power-off descent, you’ll probably need nose-up trim in order to prevent the aircraft from pitching down too aggressively.
- Pattern Work
You should use trim in each leg of the traffic pattern. Remember to re-trim the aircraft every time you reconfigure or change airspeed!
- Landing
As you enter the flare, add some nose-up trim to relieve back pressure. This helps you perfect your landing, and grease the plane on to the runway.
I trim until the purple line disappears
Trim is one of those double edge sword items when it comes to simulation. It’s a real world flight necessity, absolutely indispensable. Flying even a 152 without trim adjustment would soon drain the pilot mentally as well as physically. With the simulation, you just really want trim to be there, because it is part of the basics of flight. But at the same time it loses it’s key necessity because of the nature of the simulated controls. Need to add more back pressure when the nose drops as flaps come up? - just tilt your device toward you slightly. You forget about it before you realize. The problem is, your device doesn’t pull or push on you. The trim allows you to re-adjust the changing angle you need to hold your device to simulate compensating pressure. But I find myself cheating much of the time, unconsciously. And then the re-calibration gets done frequently enough…I think, oh well, this planes equipped with great autotrim!..I think the trim in IF is as good as it can be. SORRY ABOUT THE ESSAY
I do 25% at most
I like using lots of trim for different aircraft on takeoff and landing. 25% for the 737 and A320. 32% for the 772 and 787. 40% for anything larger.
I use 0% trim for every aircraft, but the 757 I use 20% trim for landing
The 787 and 747 for me require like 25% trim in takeoff and landing and 40 during cruise. Pretty crazy.
I honestly trim to the pink line. Depends a lot on the A/C. Flying the 77W rn on a 16 hr flight, I have it trimmed at 10.
I usually trim 7% during landing, trim setting is totally depend on the pilot and it is basically helps pilot to maintain constant pitch during ascending, landing etc .and relieve pilot from the stick pressure he has to apply to maintain the pitch
yep the 757 physics suck so I have to use 20% trim, sometimes even 100%
to keep the nose up??
Yes, yes I do.
I go 15% usually but in CRJ’ and the tri jets I got 55-60%
I usually go for 20% trim upon takeoff. But as @Z-Tube said, it varies on aircraft weight, etc. I then set trim back to 10% upon FL050, then 0% on Fl100. For landing, I don’t use any trim.
