ISA

[ADFGVX]

The manual only provides ISA -30 to ISA +30. But I regurlarly get -50. Seems odd, can anyone shed a light on that?

You mean the displayed ISA temp is -50, or your OAT is 50 below the ISA temp?

Search for the Starship POH online. It has all the power settings in there.

@jmarkows Yes, ISA temp is -50

@ADFGVX said in ISA:

@jmarkows Yes, ISA temp is -50

So what that's saying is that the ISA standard temperature is -50C. You want the difference between OAT and ISA (if ISA shows -50C and OAT is -40C, you want the ISA+10 table for example). The tables will give you OAT and IOAT also that you can use to double check, the values should line up.

Yeah ISA on this plane isn't displayed in this plane like on most. Airbus for example will take the difference between ISA and OAT and display THAT, as ISA. In this plane it seems to display what ISA should be and you have to take the OAT (not the IOAT, which to me seems more like TAT) and that ISA value to find the correct performance table to use

@Sunake Yes, I found this odd. But more power to Black Square to properly replicate this "quirk" then
