newbie question re P effect

Post by hampshireandy »

Hi Im new to the a2a 172 and ive noticed it drifts to left when climbing out and cruising. I assume this is rrplicating the p effect of real aircraft but does this mean having to constantly use right rudder throughout the flight? Or is there anything in the settings to overcome this?
Many thanks
andy

Andy,

Correct, this is Accu-Sim simulating the forces like p-factor and torque, among some other minor things than influence how a plane flies through the air.

The effect will increase and decrease throughout your normal flight phases and depending on your airmanship. Once you settle into a cruise though you should be golden once the aircraft is correctly setup.

thanks,

I know about setting the elevator trim for level flight but how would I trim for level flight once in the cruise to counteract the left dtift without there being any rudder trim on the 172?

Just like in the real aircraft you need to use the controls.a very light touch does the trick in cruise.

Your options are:
- Keep some pressure on the ailerons
- Keep some pressure on your rudder
- Use the autopilot

Thanks for all the helpful replies guys, i didnt realise there was an autopilot in the 172 so i guess that is a good option for longer flights!

Ive just found another way to counteract the right drift, put a passenger next to the pilot, although make sure they weigh less than the pilot! :D

Sometimes I wonder if individuals have set up null zones on their controls to try and force their aircraft to fly hands of in an unrealistic way. If you have a null zone set up or have reduced axis sensitivity, you may be making it more difficult for yourself to fly this realistic model.

A null zone or reduced sensitivity will require one to hold a larger deflection on their stick or yoke to correct. A null zone may also make it impossible to make the small input required to correct thus forcing one to oscillate back and forth and generally go mad. :lol:

There have been several discussions on this issue of roll, so I studied the position of my yoke during cruise on several real flights and was surprised to find that I was holding in a slight right bank with a very gentle control pressure.

Someone suggested thoughi can't remember who that it is much like driving a car. You can stay hands off for to long and you must make lots of tiny corrections to keep going on a straight line. Aircraft are no different.

I'm an autopilot abuser :shock: I will use the AP as much as possible if I am going to fly for any serious length of time....but like Oracle, I almost always have a little rudder or aileron pressure applied when hand flying :D

If you're a cheapskate like me, you need to start putting in a large deadzone after a while as the crap joystick starts building up lots of play in the springs and noise in the sensors.
