|---|---|
| D | 1,0-1,3 |
| R | 1,6-2,0 |
| Engine | Stall speed rpm |
| B4184S | 2450 50 |
| B4204S | 2600 50 |
| Normal stall speed at sea level and +20°C air temperature (speed reduces by 120 rpm per 1000 m above sea level, and 50-100 rpm per 10°C over +20°C air temperature). | |
Repeat the check with the gear selector in R.
Compare with the table.
If the speed exceeds the table values, see High stall speed ; if speed is below the table values, see Low stall speed .
