Flying Your Eggtimer
Once you've programmed your Eggtimer, you are ready for a flight. In general, a generic flight
prep procedure for a multiple deployment rocket looks something like this (assuming that you're
using switches for Power, Reset, and deployment battery power). Note: If you're NOT using a
Reset switch, the Eggtimer power should be the LAST thing you turn on... when you get the Ready
chirp, you're good to go.
At Your Prep Table
Check ALL flight batteries with a DVM and replace/recharge as necessary
Double-check your Flight Settings screen to make sure that all values are correct
Confirm that the power switch, if used, is OFF
Confirm that any deployment power switches are OFF
Confirm that the Reset switch is ON
Hook up any deployment charges with the computer and deployment batteries disconnected
Connect deployment charge shunts, if used (optional but recommended)
At the RSO Table
Prove to the RSO that the deployment channel(s) are disabled, and that no batteries have been
connected yet (along with showing them that your rocket is flightworthy, of course!)
At the Pad
DOUBLE-CHECK that the Reset switch is ON
(so that the Eggtimer will be put on hold when you turn on the power)
Connect the flight computer battery
Connect the deployment batteries
Button up the payload bay
Install the motor igniter (it would be embarrassing if you forgot, huh?)
Just Prior to Launch
REMOVE any shunts that you may be using
Turn ON the DEPLOYMENT power
If you are using the ALED/BLED LEDs and they don't come on, turn the deployment power
OFF and figure out what's wrong before proceeding
Turn ON the flight computer power (the Eggtimer will still be in Reset mode)
Turn OFF the RESET switch and wait for the Ready chirp
Connect the motor igniter to the launcher
Move to the safety area, and watch your creation blast into the sky as the LCO hits the button
If You Get an Error Tone:
Carefully approach the rocket
Disconnect the motor igniter from the launcher
Count the number of beeps to see what caused the error (there may be more than one error)
Turn ON the RESET switch to put everything on hold
TURN OFF the deployment battery power
TURN OFF the flight computer power
REPLACE any shunts that you have installed
