When should the landing gear be retracted?
Normally, the landing gear is retracted after lift-off when the airplane has reached an altitude where, in the event of an engine failure or other emergency requiring an aborted takeoff, the airplane could no longer be landed on the runway
What causes landing gear failure?
Landing Gear Failures Improper rigging Improper repairs or maintenance Parts worn beyond their allowable service limits
Which of the following conditions is most likely to cause the landing gear warning signal to sound group of answer choices?
20 (8953) – Which of the following conditions is most likely to cause the landing gear warning signal to sound? C- Landing gear not locked down and throttle retarded
Can you retract the landing gear?
Well, the short answer is no Modern airplanes have something called “Squat switch” Essentially it is a sensor, which can tell if a plane is still standing on the ground When the squat switch is activated, meaning that the plane is still on the ground, it is physically impossible to retract the landing gear
What is a fixed landing gear?
Fixed landing gear hangs underneath an aircraft during flight, whereas retractable landing gear is stowed inside an aircraft during flight Each arrangement and design is intended for a specific purpose and/or desired performance
What positions of a retractable landing gear must be indicated?
Cards Term When is the time to check landing gear switches, lights, and warning horns or buzzers for proper operation? Definition During a gear retraction check Term What positions of a retractable landing gear must be indicated? Definition Secured in the up and secured in the down position
What is aircraft belly?
A belly landing or gear-up landing occurs when an aircraft lands without its landing gear fully extended and uses its underside, or belly, as its primary landing device Belly landings are one of the most common types of aircraft accidents nevertheless, and are normally not fatal if executed carefully
How does a retractable landing gear work?
Retractable landing gear reduces an airplane’s drag, increasing CRUISE speed and glide distance For emergency gear extension, the hydraulic pressure holding the gear up is released, and the gear freefalls into the extended position; a spring helps to push the nose gear forward against the airflow
What is belly forced landing What are the causes of it?
Belly landing is an emergency landing with the gear in the “up” position This is usually caused by equipment malfunction (the gear cannot be extended or cannot reach locked position) Crash landing is a landing where the aircraft receives significant structural damage
When a landing gear safety switch on a main gear strut closes at liftoff which system is de activated?
1 and No 2 are true When a landing gear safety switch on a main gear strut closes at liftoff, which system is deactivated? A- Antiskid system
What should be checked when a shock strut bottoms during a landing?
What should be checked when a shock strut bottoms during a landing? the direction of fluid pressure allow full debooster piston travel without fluid from the high pressure side entering the low pressure chamber What is the function of a cam incorporated in a nose gear shock strut?
Where is the landing gear safety switch usually located?
A switch in the landing gear that prevents the inadvertent retraction of landing gear on the ground This switch usually is located in the port landing gear There is, however, a provision for overriding the switch so that the landing gear can be selected up on the ground, if so required
How is the landing gear extended and retracted?
Through mechanical advantage, the pilot extends and retracts the landing gear by operating the lever Use of a roller chain, sprockets, and a hand crank to decrease the required force is common Electrically operated landing gear systems are also found on light aircraft
Why is landing gear retracted after take off?
Retracting the gear into the airplane allows for a cleaner form, which reduces drag However, this is at the expense of added weight The retract system, which is usually hydraulic, must be added, and the plane must be designed to make room for the gear somewhere at least mostly inside the aircraft
What prevents the landing gear from retracting while on the ground?
There is a weight sensor which senses if the plane is on the ground This sensor prevents gear retraction while the plane is still on the ground
What is the difference between fixed and retractable landing gear?
Retractable landing gear can be raised to be inside the fusalage and wings to reduce drag but fixed gear sticks out into the airstream and causes a lot of drag and inefficiently
What is retractable undercarriage?
Landing gear is the undercarriage of an aircraft or spacecraft and may be used for either takeoff or landing Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag Some unusual landing gear have been evaluated experimentally
What are the two types of landing gear configuration?
There are two basic configurations of airplane landing gear: conventional gear or tail wheel gear and the tricycle gear
What do winglets do?
Winglets are vertical extensions of wingtips that improve an aircraft’s fuel efficiency and cruising range Designed as small airfoils, winglets reduce the aerodynamic drag associated with vortices that develop at the wingtips as the airplane moves through the air
What is required for a high performance endorsement?
A high performance endorsement is required to operate aircraft equipped with an engine rated at more than 200 horsepower Pilots must receive ground and flight training from an authorized instructor in a high performance airplane and then receive a one-time endorsement in the student’s logbook
Is a Cessna 182 complex?
ANSWER: A complex aircraft is one which has manually or automatically controllable pitch propeller, flaps, and retractable landing gear List of high performance aircraft includes: Cessna 182, Cirrus SR22 Note that these aircraft do not have retractable gear
Can a plane land with a flat tire?
Answer: Most modern airliners have more than a single tire on a landing gear If the pilots know a tire has failed during takeoff at low speed, they will abort the takeoff At high speed they will go ahead and take off, then return to land for a safety inspection
How do planes land with no visibility?
Question: How does a pilot land a plane during heavy rain and low visibility? Answer: Pilots use precise navigation equipment, usually the Instrument Landing System (ILS), to maneuver the airplane laterally and vertically to land on the runway If an ILS is not available, GPS or other navigation aids are used
What happens if a plane lands too fast?
When it happens, it’s called wheelbarrowing, and it can lead to a loss of directional control, prop strike, or nose gear collapse On top of those problems, with little to no weight on your main landing gear, you have little braking action
