EMERGENCY PROCEDURES
RSUK0287_POH_Cavalon Revision 2, Issue Date 24.06.2015 3-7
1. Gauge suddenly goes to full scale deflection, other gauges reading normally –
likely gauge fault
2. Oil pressure falls to zero, possible loss of pressure. Stop engine, make
precautionary landing
3. Water temp gradually or suddenly rises above max temp. Possible loss of
coolant. Stop engine, make precautionary landing
4. Oil temp suddenly falls to zero, other gauges reading normal – probable gauge
failure.
5. Oil temp rises above maximum, other gauges normal – possible very low oil level,
blocked radiator or thermostat. Stop engine, make precautionary landing.
6. Fuel level gauge suddenly falls to zero or FSD. Probable gauge failure, but
always cross check to predicted fuel burn. Low fuel light will light as a backup.
Sudden, large deflections are normally unlikely, with the exception of loss of pressure
readings.
3.11 Door open in flight.
A door open in flight is NOT catastrophic. The door hinge line is angled to the oncoming
airflow such that if left open before take-off, or opened in flight, the oncoming airflow will
naturally close the door.
Note, yawing the aircraft such that the open door is downwind will allow the door to open
more, but on straightening out the oncoming airflow closes the door. If the yaw is such that
the open door is upwind, then the oncoming airflow keeps the door firmly shut.
In the event of this occurrence, fly the aircraft and ignore the open door until it is safe to lock
it. This will be either on the ground, by a passenger (if it is on their side) or by slowing and
trimming the aircraft at a safe speed that allows the pilot to release hand(s) for the closure
task.
