tables designated with 3 and 4 are speed vs load factor in stable (sustained?) turn for different altitudes, with 50% of fuel, 2x r73, and 2x r27, at standard temperature. Table 3 is for max dry power, and table 4 is for max AB. At table 4, hidden line indicates overload area while long red lines indicates area of "volatile instrument readings".
Correction for different aircraft mass is: final load factor= initial load factor * 20000 / mass of aircraft.
Tables designated 5 and 6 are predicted altitude lost in recovery from different initial speeds, dive angles and for different load factors during recovery, at idle power, with 2x r73, and 2x r27. Follow red line. Table 5 is for speed brake closed and table 6 is for speed brake open.
Just a note, all fuels are given as "50% of normal amount of fuel", which doesn't necessarily mean 50% of fuel tank. Maybe it is, maybe it is not, I don't know.
