Basic Flight Instructions
Before Each Flight
ΠPress and hold the button to bring up the menu
Let go of the button when you see Launch
You should see Ready on the screen.
You are ready to fly!
After Each Flight
ΠYou will see each of the data items for the flight
The flight has been stored; you can turn the altimeter off or
perform other activities safely.
Flight Logic
•
AltimeterTwo senses launch by sensing acceleration. Try not to bump
or jostle it too much as you load it on the launch pad, or it will sense
a false launch and collect nonsense data. If you ever have a flight with a
very low altitude, it is probably because of rough handling just before
launch.
•
AltimeterTwo will automatically turn off after 2 hours from the time
that the button was last pressed, or from launch.
•
If you have a flight where Coast-Apogee and Apogee-Eject times
are roughly the negative of each other, this is because AltimeterTwo
mistook a rapid deceleration after burnout as ejection.
•
For multi-stage flights, AltimeterTwo will report Thrust Time, Accel-
eration, and Top Speed based on the first engine only. Coast to Apogee
time will begin after the first engine burnout and include subsequent
stages. Apogee to Ejection Time and Ejection Altitude will not be
reliable. Max Altitude, Descent Rate, and Flight Duration will work as
usual.
