This is my official plane Classification. It helps me name aircraft and classifies them into many different distinctions. You may use this classification as you wish, just if you upload an aircraft utilizing this, somewhere in your description please say (without quotes) "This Upload Uses Walnut's Plane Classification". This classification appears complex, but examples are abundant throughout the page, so without further ado, Enjoy!

Dr - Drone

A - Attacker

X - Scramjet (Hypersonic jet with a powerful laser cannon used to blast other aircraft from far away. These aircraft are often at Mach 5 or even Mach 10 in Simpleplanes standards. For more info, watch this video

H - Helicopter

PL - Patrol

AERO - Aerobatics craft/Stunt craft (Ex: Blue Angels)

AG - Attack Glider

T - Trainer

TA - Test Aircraft (used to test experimental weapons from other aircraft)

PT - Personnel Transport

C - Civilian/civil

CG - Cargo

MR - Multirole

F - Fighter

B - Bomber

CB - Carrier-based

S - Stealth

R - Recon

I - Interceptor

GA - Ground Attack

D - Defence (defending convoys, bombers, bases, etc).

EX - Experiment

GS - Gunship

N - Naval

V - Vehicle

AAF - Anti-Air Flak vehicle

AV - Attack Vehicle

GtAV - Ground to Air Vehicle

DB - Dive Bomber

HM - Historic Model (for when I build an aircraft originally from a very real historic aircraft, but it's not a replica.)

Example: CBSF-71 Mk XIV = Carrier Based Stealth Fighter. Mark 14

Aircraft number (F-##) is based on the part count. (edited in 2/4/2018) If it's a small plane, you add the third digit with the other numbers (139 = 13 + 9 = 22). if the answer is still three digits, repeat the adding step until it becomes right. And if it's STILL a three-digit number, then just leave it out. Lastly, if it is SOMEHOW the same name as another plane, then just take the number and minus 1. (38 - 1 = 37)

Marks (Mk # in Roman Numerals)

I - 1
II - 2
III - 3
IV - 4
V - 5
VI - 6
VII - 7
VIII - 8
IX - 9
X - 10
XI - 11
XII - 12
XIII - 13
XIV - 14
XV - 15
XVI - 16
XVII - 17
XVIII - 18
XIX - 19
XX - 20
XXI - 21
XXII - 22
XXIII - 23
XXIV - 24
XXV - 25 (UPPER LIMIT)

ENGINE CLASSIFICATION

P - Propeller (It's a propeller engine)

J - Jet (It's a jet engine)

P.## (like with normal aircraft, this is part count)

J.26 - Jet engine, 26 parts

Weapon Classification

MG - Machine Gun (damage of 14.9 or lower and fire rate must be REALISTIC)

CNN - Cannon (damage of 15 or higher and fire rate must be REALISTIC)

RG - Rotary Gun/Minigun (must be the minigun block and can't have a lower fire rate of 15 Rounds Per Second)

LS - Laser System (MUST be a fire rate of at least 50 Rounds Per Second or more and a spread rate of 0.1 or less)

How to Name the Weapon
put in what the weapon is, add a dash (this -), add the number of damage on it (default is 8), and add the mark. Example: A laser in its 2nd mark with 25 damage would be called the LS-25 Mk II

Bomb/Rocket Classification

BMB - Bomb
RKT - Unguided Rocket
MSL - Missile
WMD - Weapon of Mass Destruction (Bomb that holds 10-19 explosives inside)
NCW - Nuclear Weapon (holds 20 or more bombs inside)
PCM - Pilot Controlled Missile
GB - Gliding Bomb

BMB/RKT/MSL/PCM # - Part Count

Example - MSL-6 (Missile with 6 different parts)

If it is a modified base part, name it by the fueltime/range

Example - MSL-60100 (Missile, fueltime 60, range 100)
