landing flap
Low (Specialised/Technical)Technical/Aviation
Definition
Meaning
A hinged or movable control surface on the trailing edge of an aircraft wing that is extended to increase lift and drag during landing approach.
Primarily a technical aeronautical term; can also be used in other fields metaphorically to describe a mechanical part or device that lowers or extends to facilitate a controlled descent or landing. No significant extended metaphorical use in general language.
Linguistics
Semantic Notes
This is a highly specific compound noun with a fixed technical meaning. It is a subtype of 'flap'. The term is almost exclusively used in the context of aviation and aerospace engineering.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or form. Both dialects use the same term identically in technical contexts.
Connotations
Neutral, purely technical in both regions.
Frequency
Equally low frequency in both, confined to specialist domains.

Usage
Context Usage
Business
Rare, only in aerospace manufacturing or airline maintenance reports.
Academic
Used in aeronautical engineering, physics of flight, and aviation textbooks.
Everyday
Extremely rare. Only used by pilots, aviation enthusiasts, or in very specific news reports about aviation incidents.
Technical
The primary domain of use. Precise term in aircraft design, piloting, and maintenance manuals.
Examples
By Part of Speech
verb
British English
- The pilot will land with the flaps fully extended.
- The co-pilot is landing the aircraft manually.
American English
- The pilot will land with the flaps fully deployed.
- The first officer is landing the airplane manually.
adverb
British English
- The plane descended slowly for landing.
- The flaps were lowered fully.
American English
- The airplane descended slowly for landing.
- The flaps were extended fully.
adjective
British English
- The landing flap mechanism is being inspected.
- We observed the landing flap deployment.
American English
- The landing flap actuator is being inspected.
- We observed the landing flap extension.
Examples
By CEFR Level
- The big plane has flaps on its wings.
- The flaps help the plane land.
- Before landing, the pilot extends the flaps on the wings.
- The landing flaps make the wing bigger to create more lift at slow speed.
- A fault in the landing flap system forced the aircraft to abort its approach.
- Engineers are checking why the left landing flap did not deploy symmetrically with the right one.
- The innovative design of the variable-camber landing flap significantly reduces noise during the final approach phase.
- Post-incident analysis focused on the hydraulic pressure loss that prevented the landing flaps from achieving their fully extended position.
Learning
Memory Aids
Mnemonic
Think of a bird lowering its feathers to slow down and land softly. A plane's LANDING FLAP is like those feathers – it FLAPS down for a safe LANDING.
Conceptual Metaphor
A MECHANICAL WING is a BIRD'S WING (the flap mimics the function of feathers adjusting for descent).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'посадочный клапан' – 'клапан' is incorrect. The correct term is 'посадочный щиток' or 'закрылок'.
- Do not confuse with 'landing gear' (шасси).
Common Mistakes
- Using 'landing flap' to refer to the landing gear (the wheels).
- Saying 'landing flag'.
- Using it in non-aviation contexts where it would be confusing.

FAQ
Frequently Asked Questions
No. Landing flaps are on the wings and change their shape. Landing gear refers to the wheels and struts that support the aircraft on the ground.
Nearly all modern fixed-wing aircraft, from small trainers to large jets, have some form of flap system to aid landing. Some very simple or vintage aircraft may not.
It is highly unlikely. It is a technical term. In everyday conversation, people would just say 'the flaps on the plane's wings' if they needed to mention it.
Both are high-lift devices. Flaps are on the trailing (rear) edge of the wing. Slats are on the leading (front) edge of the wing. The term 'landing flap' specifically refers to the flaps used during landing.
