In this great photo the large blank area used to house the Decca navigator paper moving map - leaving us with similar Nav capability as found in a Piper Cherokee...
Anyway how to start the 1-11 APU ( this is from memory) Having checked the engineers are not refilling the oil and all cockpit preperation checks are complete it went something like this;-
Battery master switch ON
Fire detection test switch to APU
Squib test switch to TEST - check squib lights on
Switch "APU CONTROL" to "ON".
- Check "FUEL VALVE" reads "OPEN".
- Click "PUSH TO START" (gulls eye initially reads "START"). After 35% RPM "START" goes blank then displays "RUN" when at full RPM.
Select APU generator ON
Select Electrical power source selector to APU and check voltage....et voilą you can make a cup of tea
