Description
On pilot's demand the smoke system produces a trail of
smoke by injection of smoke oil (straight paraffin oil) into
the engine exhaust. The smoke oil is vaporised by the exhaust
gas heat and is visible as dense smoke after leaving the
exhaust.
From SN LT011 the smoke system has been changed. The
smoke acro tank and the smoke tank drain have been placed
in the middle of the aircraft (refer to Figure 1, Sheet 2).
The system consists of (refer to Figure 1):
