FUEL LOW ALARM
Fuel low alarm is only available is your aircraft is equipped with a fuel flow sender or fuel level
sender.
The Stratomaster Ultra will warn you once your aircraft's fuel level falls below a
predetermined level (Refer fuel low alarm page 47) by flashing the wording "Fuel level low"
across the bottom row of the display every eight seconds for eight seconds. This display field
will remain flashing and it is not possible to acknowledge the alarm.
Fuel low alarms can be set in increments of 1 liter, 0.2 Imperial gallons or 0.2 US gallons.
The highest fuel level, which can be entered is 250 liters (54.9 Imperial gallons or 65.9 US
gallons). When setting the alarm factors such as engine type etc. should be taken into
account. It is the pilot's responsibility to ensure that the alarm is correctly set prior to take-
off.
The fuel low alarm can be switched off should you not wish to make use of this function.
(Refer fuel low alarm page 47).
Should your aircraft not be equipped with either a fuel low sender or a fuel level sender then
the fuel low alarm should be switched off to prevent the fuel low alarm from flashing during
flight.
INSTRUCTOR MODE
The Stratomaster Ultra can be set to either instructor mode or normal mode. (Refer instructor
mode page 50) When set to instructor mode it enables instructors to time and log lessons
instead of flights. A lesson could consist of multiple flights. Provision is further made for a
student number, thus by viewing the log the student who flew the lesson can be identified. A
maximum of 250 student numbers can be entered.
Air time since take-off field shall now display lesson time.
A lesson will have to be started and ended manually. Should the letter "P" flash in the ASI
field this indicates that a lesson has been primed. Should the letter "A" flash in the ASI field
this indicates that a lesson has been activated. Should your Stratomaster Ultra be set to
manual detection of flight and the flight is started manually before a lesson is started then no
flashing A or P will appear.
Primed
: Lesson has started but no time has accumulated yet. The instrument is now waiting
for revs to reach hobbs revs or take-off revs depending on setup.
Active
: Conditions for starting time accumulation has been met. Time is now accumulating if
revs are higher than hobbs revs setting.
