Aircraft Manufacturers Codes can be found here
First shown is an aircraft’s model name/number, then the year of its appearance or first manufacture. ATC or Group-2 certifications, if any, follow in parentheses, after which its specifications begin. Descriptions will be clear once logical initials are recognized. An aircraft might be shown, as an example: 2pOlwMFb, which translates into accommodations and physical description (in this example a two-place open low-wing monoplane flying boat):
p = place or passenger (the number for multi-place aircraft may or may not include crew); O = open cockpit; C = cabin or canopied cockpit; O/C = open or closed cockpit; O-C = optional or convertible open/closed cockpit; lw = low-wing; mw = mid-wing; hw = high-wing; sw = sesqui-wing; B = biplane; M = monoplane; T = triplane; Ag = autogyro; Am = amphibian; F = pontoon floatplane; Fb = flying boat; H = helicopter.
Next are incidental codes: rg = retracting gear; hp = horsepower; load: = useful load (gross minus empty weight); v: = speed (max/cruise/landing or stall—mph unless otherwise noted, single entry is max unless otherwise noted; kts = knots, nm = nautical miles); ff: = first flight; wt: = weight (pounds); underline = principal designer(s); p: = pilot; $ = unit cost, usually at first release; POP: = population, the number built of a specific entry;  = registration(s), sometimes limited to a representative or notable few in large civil productions; ? = unknown data; x = missing or questionable data; (>) = conflicting data from an authoritative source.
All information is based on found data, nothing has been “guesstimated.” Performance figures can differ greatly in horsepower and speed between sea-level and altitude; useful loads might represent either design gross or maximum service loads; ranges can differ with empty or loaded readings and vary greatly with special equipment. Prices ($) are generally those advertised by the manufacturer.
