The first part of the summary shows you the flight settings that were used, the second part shows
you the elapsed time and altitude for each major flight event. It also shows you the measured ASL
altitude of the launch site, the temperature, the beep code (in case the flight was aborted), the flight
status code (more on that later), and the total elapsed time of the flight. All times are in
milliseconds, so 2.5 seconds would be 2500 milliseconds.
The flight status is updated by the Eggtimer as the flight progresses, and saved into the flight
memory. In the event that for some reason something goes wrong, you can use this value to help
you figure it out. The status codes are:
0 - Flight Not Started (in programming or pre-Ready mode)
1 - Waiting for LDA
2 - LDA reached
3 - Not used
4 - Airstarted on CHB (if selected)
5 - Mach Lockout expired (< 100 ft/sec for over 1 second, after LDA)
6 - Nose-Over
7 - Drogue on CHB (if selected)
8 - Main (CHA) deployed (if selected)
9 - Landing detected
Most of the time after a successful flight, this code will be a "9". If the rocket gets stuck in a tree,
for example, and the landing altitude is never reached (< 30 ft for at least 5 seconds) this will end up
being the last previous flight phase; for example, if it was a multiple-deployment flight, the last
status code will be 8 (Main Deployed), if there was no deployment selected it will be a 6 (Nose-
Over).
As you can see from this data, the rocket got to 1347 feet, had a maximum velocity of 565 feet/sec.
The actual LDA was 118 ft at 350ms into the flight, it was set to 100 ft. The burn timer expired at
2350 ms, 2 seconds after LDA, at 855 ft. Nose-Over and CHB (drogue) fired at 1337 ft at 8850 ms,
and the main (CHA) fired at 196 ft at 43350 ms.
