Pre-flight checklist

Here is the first draft of my pre-flight checklist.

Certain things will not go into this (like checking the parachutes – this will happen BEFORE I arrive :>), but this will be used to capture everything I’m going to need to do. I have a feeling my brain will turn into mud the day of the launch, so this document will be key.

If you think I’ve missed something, please tell me!

[ ] Check weather report!
[ ] talk with RSO
[ ] Provide Ham frequencies that will be used
[ ] Find compatible pad’s, and discuss timing
[ ] Ask RSO about any requirements he/she may have prior to prepping the rocket.
[ ] Provide hard copy of Rocksim data for altitude expectations
[ ] Assembly:
[ ] Dry fit components (clean/sand/tape/powder as necessary):
[ ] Nose Cone / Nose Cone Bulkhead
[ ] verify bulkhead fits and Eye-Nut Adapter will secure on allthread
[ ] Nose cone / upper airframe
[ ] verify shear pin holes line up between airframe and nose cone shoulder

[ ] Verify screw switch is OFF (at least 1/4 turn counter clockwise)
[ ] Install 9 Volt battery
[ ] secure 9 volt battery with tie wrap or duct tape
[ ] turn screw switch on (clockwise until hand tight)
[ ] ensure Raven beeps out appropriate voltage (9 beeps)
[ ] wait for Raven to enter pre-launch mode (low single beep every 2 seconds)
[ ] install Q2G2 ematch in Apogee terminal block, ensure Raven beeps out proper terminal and resistance. then remove

Chan1 Apogee
Baro Only
Delay 0

[ ] Watch screen for Channel 2 programming – ensure it is correct. screen will have:

Chan2 Main
Alt 700
Delay 0

[ ] Wait for countdown timer to reach 0 to enter pre-flight mode. DON’T TOUCH THE JOYSTICK!
[ ] Ensure Maras4 beeps out pre-launch mode (5 beeps)
[ ] Verify on screen POST tests screen will say the following:

Sensors OK – this indicates there are no malfunctions in the Baro or Accelorameter.
IC2 W OK – this indicates it would write data to memory properly
IC2 R OK – this indicates it could read data from memory ok

[ ] Wait for 3 LONG beeps from Marsa4 to indicate it will check the pyro continuity
[ ] Verify on screen that continuity has passed – screen will say

Pyro Test Pass
