The A2A Simulations Community

I read this in another thread:


(Quoted from the thread 'Accusim status for P-51')

In the begining of using the Accusim aircrafts so did also I had problem with this. But I figured out a way to remember it(I am sure many other's also use this way to remember it),

- Higher oilgrade for higher tempratures and lower oilgrade for lower tempratures.

I hope this will help some. And if people have other ways to remember such things so please post it here. Like I still have problem of how to recounte Fahrenhight to Celsius, so if some have some great way for remebering that I would be glad to hear it.

An easy way to convert Celsius to Fahrenheit is this, but it is only a rough estimate:
Multiply your Celsius figure by 2, then add 30. Hey presto, one rough Fahrenheit figure.

Matt

Thank you for your answers. But pjc747, I think you missunderstood my question a bit, but it was good that you posted the formula. My question was more if you have a tips of how you remeber this numbers and way to calculate it.

Matt, that is great way to count it for making quick decissions, when you do not have time to count the exact one, and you do not need the exact number some times.

Another thing someone may have a tips for is how to recount the different speeds, miles-/kilometers- and knots per hour? A tip for how you in an easy way recount them.

Very rough but the ones I use...

KPH = Knots x 2 - 10% (and over 150knts add extra 10kph back on, over 450knts add 20kph back on.)
eg 80knts = (160 - 16) = 144 (actually 147)
eg 251knts = (502-50+10) = 462kph (actually 462)
eg 300knts = (600-60+10) = 550kph (actually 552)
eg 460knts = (920-92+20)= 848kph (actually 846kph)


Knots = MPH minus 10% and round down to nearest "10"

eg 80mph - 8 = 72 = 70knts (actually 69.57knts
eg 240mph - 24 = 216 = 210knts (actually 209knts



MPH = Knts plus 10% round UP to nearest "10"

eg 210knts = 210 +21 = 231 = 240mph (actually 241.5


Those are the quick and dirty methods I use. They will get you to where you are going within Private Pilot tolerances..and sometimes within Commercial tolerances.

Killratio, thank you for that great post, that was a technique to recount speed I have not seen before, very usefull.
(Have seen your fantastic Spitfire cockpit, and also send you a pm, your cockpit is more than fantastic.)




Well, it may just be the language barrier, but I will rather say that you explained Mattgn's figure. Cause his answer was already correct, and it did not become more correct. So I will say that you explained where his correct figure came from. It does not matter so much, but correct should be correct, hihi.

And also, if persons here have other tricks and tips about such stuff as the above, please post it, it is usefull for everyone.

Here's another rough one that I use:

The chance of survival is inversely proportional to the angle of arrival



(pm answered, cheers)

Hehe, nice one Pauline
I suppose you could tack onto that something about your very own classic, "Independent Descent Profiles".
"Try to maintain physical contact between the fuselage and wings, as their independent descent profiles reduce chances of survival accordingly."
