Did a little flight around KSFO and the Bay area this afternoon. This one is long - starting from cold and dark; checking the outside air temp and selecting the oil for the conditions; firing up the engines (realistic engine starting); allowing them to warm up; tuning in some nice flying music (good thing to pass the time while the engines warm up!); taxi; takeoff; landing; taxi and shutdown.
As a slight aside, just about the only thing that doesn’t seem to be saved from one session to another: the radio station. I flew in the same area yesterday and had music tuned in. Today, when I started the radio, I had to scan through several bands to find some music.
It should but it seems not to be right. If you Oil gets over 100° things start to go wrong, that would be a sign, that it is showing °C or is wrongly scaled. If I keep my oil around 80-90° on that scale my engine never dies.
Well the ability of radials to convert oil to blue smoke (and splatter anything left over everything in sight) , rapidly and efficiently, is renowned !
Though that works out at something like a pint every 4 minutes which does seem a lot.
Temperatures below 180 °F (80 °C) are problematic as it is not hot enough to burn off water in the oil.
Temperatures above 225 °F (105 °C) in air cooled engines are also problematic.
I am not sure of the recommended range for these engines but it is going to be somewhere in the 85°C to 100°C range I suspect. Your 80-90° range sounds correct for °C.
No autopilot, no assistant landing instruments, no tower/approach communications with some frequencies possible. But I love it so much!
Tried to scan all of those 5 Freq Bands, but I still cannot hear any classic music. How could some of you get the music during flight? Please give me some hints with particular freq. and bands if possible (or it changes randomly for each flight?)
How much is the safe range to control the oil pressure and temperature of 247d?
Sometimes the oil pressure will exceed 120. I don’t know how to reduce the oil pressure. It’s useless for me to lower the throttle lever.
My oil temperature is mostly 40-60, which is not the appropriate range.
So far, I have only successfully flown to the destination twice. The rest of the time, two engines fail at the same time on the way. My rpm is 2000, and the power of the engine is lower than 29, which is on the left of the white area.
Please tell me the correct operation. Thank you. It’s going crazy.
High oil pressure = low oil temp // low oil pressure = high oil temp
You have a couple of levers to control the oil shutter, that’s what you use to control the oil temperature.
Check your carb temperature, make sure it’s above 100F
It’s a bit more complicated, as the developers built a database of 273 simulated AM music stations into the product. There’s a CSV file of them inside a sub folder which itself inside the plane’s Documentation folder. But I don’t know the details of how the plane implements those stations, as they seem to change between flights. E.g., I had music tuned in at shutdown of a previous flight to/from the same airport as tonight, but with tonight’s session, I had to scan the various radio bands to find music again.
Just absolutely makes me - for real - laugh out loud.
People have been asking for “Study Level” since August 2020. Now that we actually have an aircraft that requires serious STUDY of the methods needed to properly fly her, I read complaint after complaint.
Listen: in real life if you get it wrong you crash. Hopefully you get to walk away (as did Harrison Ford) with only minor injuries. And, if memory serves, Harrison Ford didn’t get it wrong. In fact, he did everything absolutely right. He “read the manual.”
All aircraft have failure points that need to be controlled. Otherwise, they fail. Sometimes, they fail even if you do everything right!
And for those that haven’t read the manual for the Boeing 247D - excellent by the way - this is directly taken from Section 4: MSFS Limitations
The failure model of MSFS is rather simplistic and to make matters worse, not entirely accessible through the different programming interfaces. Consequently, all malfunctions in our Boeing 247D add-on are custom-coded and work independent of any settings in the sim. Therefore, please make sure to keep the malfunction in the MSFS settings turned off and instead use the Boeing’s clipboard to toggle various realism options for the aircraft.
I think there are some issues saving the state of the switches between flights, so that might account for that. I always move all the switches back to off or I move them around to make sure the plane registers the correct position of the knob/switch when I start a new flight.
Most of the “good stuff” in this aircraft seem to arise from custom coding to get around limitations of the basic sim. I suspect even things like issues interfacing with the Asobo default AP with key commands arise from the fact this is a bespoke aircraft that has to work around the very limited options the base sim provides.
I checked some variables. The flightmodel is using °C celsius to compute the temperatures and the simulation is quite astonishing. They have dozen of points of the oil circulatiopn where the oil temperatur is computed & measured. Really amazing. But the needle indeed seemns to show °F. But maybe some formulas are not correct, as I really only have problems if the oil exceeds 100° on the gauge. And for °F that would be way to early to cause problems.
If you oil gauges shows 40-60 °F temeprature just shut the oil coolers and open the carb heats. It will need some time, but the oil temp will sloooooooowly rise and the pressure will drop. Due to my testing I figuered optimal Oil Temp Needle Indication is around 80-90 , then the Oil Pressure is in the 70-90 PSI range.
I’ve finally got to do a legit flight of some substance and it was a great experience. I have noticed something odd though. This plane at least on my system seems incapable of consecutive flights. Yesterday I kept crashing trying to load it and the only remedy was to load a flight with a different aircraft, exit the sim and load it again, and then select the 247 and I was able to do a flight. Today same thing, i load the sim and the 247 and the sim locks up on the flight loading screen. Only after I loaded a flight with another plane and restarted the sim was I able to load a flight with the 247 again. Other have mentioned problems with the saved states, I wonder If my issue is the loading of them.
There are known issues with state saving. Just cycle all levers and controls to off and then back to on. Try and remember to shut everything down when you log out to avoid the issue.
