[LUNAR Announce:] Flying Saturday 01/13/18

[Anthony Cooper]

LUNAR did not get a 2018 FAA waiver yet. We have decided to fly on Saturday
but it will be an unwaivered launch. What does that mean? Simple answer is
no HP rockets. Real answer is a little more complicated. Below is a page I
create back when I got my Pyro III license. The blue text is the governing
rules. Your rocket must be under 3.3 pounds, have motors with no more than
125g of propellant and have less then 80 Newtons average thrust.

You want to fly bigger rockets?

This table is suppose to make it easier. You need to know your Gross Lift
Off Weight (GLOW) and your motor(s) specifications. Start from the top left
of the table and keep going down and right until you meet all the
requirements. The last cell will tell you what you have to do to fly your
rocket.
Proxitity to Airport Rocket Weight GLOW Single motor Multi Motor Average
Thrust Restriction
> 5 nautical miles <1500g/1lbs <62.5g Typical G motor and <160N-Sec <125g
and <320N-Sec <80N Standard
> 5 nautical miles <1500g/3.3lbs <125g Typical H motor <125g <80N Pyro III
< 5 nautical miles >1500g/3.3lbs <10240N-Sec M motor limit <20480N-Sec >=80N
Waiver
< 5 nautical miles >1500g/3.3lbs <40960N-Sec O motor limit <40960N-Sec
>=80N Not
CA legal, use another state
< 5 nautical miles >1500g/3.3lbs >=40960N-Sec O motor limit >=40960N-Sec
>=80N Not USA legal

*Standard* = Permission of the land owner, insurance, and a fire permit.
*Notice* = No longer used. "Large Model Rockets" (>453g & <1500g GLOW,
>62.5g & <125g propellant, >113g & < 125g total propellant in multiple
motors) was dropped from FAR 101.22.
*Waiver* = Standard plus a waiver filed with the local FAA controller and a
CA Pyro Technician Class III Rocketry. FAR 101

*Pyro III* is required when: a rocket that (1) is propelled by one or more
high power rocket motors (more than 160 Newton-seconds (36 lb.-seconds) of
total impulse or an average thrust greater than 80 N (18 lbs) or more than
62.5 g (2.2 oz) of propellant,) ; (2) is propelled by a combination of
model rocket motors having an installed total impulse of more than 320
N-sec (71.9 lb-sec); (3) is propelled by a combination of model rocket
motors having more than a total of 125 g (4.4 oz) of propellant weight; or
(4) weighs more than 1500 g (53 oz - 3.3lbs) with motor(s) installed.

Motor = Impulse
1/4A < .625NSec
1/2A < 1.25NSec
A < 2.5NSec
B < 5.0NSec
C < 10NSec
D < 20NSec
E < 40NSec
F < 80NSec
G < 160NSec CA Pyro III required for a single motor over 160NSec.
H < 320NSec CA Pyro III required for a multi motor cluster or staged over
320NSec.
I < 640NSec
J < 1280NSec
K < 2560NSec
L < 5120NSec
M < 10240NSec Single motor limit for CA
N < 20480NSec Multi motor limit for CA
O < 40960NSec Experimental motor limit for USA
