Low oil pressure on startup

c172p-team/c172p-detailed

After starting the engine, the oil pressure does not rise to the green arc if the throttle remains at idle. If more throttle is applied then the pressure does come to the green arc and remains stabilizes there. According to the checklist, the oil pressure should reach the green arc (50 PSI) after 30 seconds from engine startup (or 60 seconds at most during cold weather).

I don’t know enough about the Cessna, but certainly on my aircraft the oil pressure comes up within a couple of seconds when the engine starts, and stays in the green arc irrespective of the throttle position.

On the ground, the oil pressure falling below the green arc would be a reason to immediately stop the engine to avoid engine damage.

Carburator Icing

Harald67/c150

Another interesting topic, could we simulate carburator icing? -usually happens when the air is cold and the power is low -doesn’t require temperatures below 0! (due to lower pressure the aspirator generates) -coming icing shows through lower RPM while throttle stays the same -leads to engine failure if carburator is not heated during beginning icing

Spark plugs fouling

c172p-team/c172p-detailed

Spark plugs can clog and eventually foul if the engine is allowed to idle too low for too long. Throttling up an engine with oil-soaked spark plugs can help clear them out.

The engine should be at or above 800 RPM. Failure to do so may cause spark plug fouling. If the plugs do foul (the engine will sound rough), running the engine at a higher RPM will blow them clear within a few seconds by doing so.

Possible to simulate?

Preflighting the C172 with outside view

c172p-team/c172p-detailed

So I took this for a test flight and preflight today. A few notes: - The fuel tank quantity and sampling dialogs are neat. However the quantity could be also shown in liters in addition to gallons and pounds. - Fuel sump clickpoint is a bit hard to find, maybe combine all fuel related stuff to one dialog and tie it to a big clickspot on the fuel tank itself? So that it shows quantity and lets you take the sample as well. - Is there a way to disable clicspots (and tooltips) from within the cockpit when you are in an outside view? There is a lot of stuff that is clickable and shows tooltips in the cockpit that gets in the way when you try to do a preflight check in an outside view. Same with outside clickspots when you are in the cockpi. I often accidentally clicked the engine oil clickspot when I used the GNS196.

Improve primer

c172p-team/c172p-detailed

Improve primer and its procedure, model a reservoir tank (as suggested by tigert in the forum thread), take into consideration external temperatures and if the engine is cold / warm, better procedures for flooded engine, etc.
