This forum post from r/flying is a crowdsourced glossary thread rather than a news story, but it captures something genuinely useful to working pilots: the informal vocabulary that flight crews use to describe aircraft handling characteristics that don't have precise technical definitions in any AFM or FCOM. The original poster cites two terms — "brick" for an airplane that is very draggy in a power-off configuration (meaning it drops out of the sky quickly once thrust is removed, offering little glide performance) and "dog" for an airplane with poor climb performance (typically underpowered relative to its weight or wing loading). These terms exist because certification documents and performance charts quantify things like glide ratio, climb gradient, and drag coefficients numerically, but pilots need quick shorthand to communicate "feel" and relative performance to each other, especially when transitioning between aircraft types or briefing less experienced pilots.
This kind of slang matters more than it might first appear, particularly for pilots who fly multiple types or who are checking out in unfamiliar equipment. Terms like "brick" carry real operational implications — an airplane that glides poorly demands earlier decision-making on engine-out scenarios, more conservative traffic pattern management, and tighter margins if an engine fails on a multi-engine aircraft or if a single-engine airplane loses power. Similarly, calling an airplane a "dog" on climb has direct relevance to density altitude planning, obstacle clearance calculations, and go-around performance at high-elevation or hot-and-high airports. Flight instructors and check airmen often rely on this kind of informal characterization to set expectations before a student or newly rated pilot ever pulls power to idle or attempts a maximum-performance climb, supplementing — not replacing — the official POH numbers.
The broader significance lies in how this kind of tribal knowledge gets transmitted across the aviation community, especially as flying becomes more geographically and generationally dispersed. Historically, this vocabulary passed from instructor to student, from captain to first officer, or among mechanics and line pilots at a single FBO or airline base. Online forums like r/flying have become a de facto clearinghouse where pilots from GA, corporate, and airline backgrounds compare notes on aircraft-specific quirks that don't show up in type-specific training materials. Terms like "floater" (an airplane that won't settle onto the runway during landing, often due to ground effect or excess airspeed), "slippery" (low parasite drag, tendency to accelerate quickly in a descent), "barn door" (high-drag flap or gear configuration), and "widowmaker" (historically applied to aircraft with unforgiving stall/spin characteristics, like early Bonanzas or the F-104) are examples that populate this same lexicon.
For corporate and airline pilots moving between fleet types, or for instructors building risk-mitigation briefings, this kind of slang serves a genuine safety function by compressing complex aerodynamic behavior into memorable, quickly communicated concepts. It's a reminder that stick-and-rudder culture and informal knowledge transfer remain vital even in an era of standardized SOPs, FOQA programs, and highly quantified performance engineering — pilots still need a shared, intuitive language to talk about how an airplane actually behaves, not just what the numbers say it should do.
