7.6 Air in the Fuel System (During Flight)
1. Move the fuel tank selector to a tank with sufficient fuel
2. Electric fuel pump (if installed) - "ON"
3. Engage the starter
7.7 Oil Pressure too Low (During Flight)
1. Reduce power as quickly as possible
2. Monitor the oil pressure:
a) If the oil pressure rises into the green, continue flight
with a power setting which keeps the oil pressure in the
green, if possible.
b) If the oil pressure remains too low, expect engine failure
and prepare for an emergency landing.
WARNING:
If there is air in the fuel system, the engine stalls within a few
seconds. It takes about 15 seconds before the engine restarts.
WARNING: The high-pressure pump has to be inspected before the next
flight.
Note: If the engine fails due to low oil pressure, the propeller will also
stop turning. The glide ratio of an aircraft with a stopped
propeller is higher than with windmilling, so that the range for an
emergency landing increases. Related data in the Pilot´s
Operating Handbook must be taken into account.
