Tire preservation

  • Tire preservation Israel Jantzen

    Why has someone not designed a landing wheel with a fin or fins on it so that the air will start the wheels turning before the wheels touch the ground? Wouldn't that preserve the tires longer from wear? Or would it make the control of the aircraft more dangerous in some circumstances, such as rain or snow, to have the wheels already turning when landing? If so, perhaps the fins could be manually or computer controlled for various weather conditions.

  • I've now seen several landing strips up close and there are lots of tire tracks from planes' landing wheels. I wonder if it somehow modifies the properties of landing strips to make for poorer landing conditions. Do landing strips suffer from lots of tire tracks?

  • When moving to and from the runway, does a large passenger aircraft turn by changing the thrust difference on its side engines, or by turning the front landing gear to a different angle? If it is by turning the front landing gear, through what device does the pilot control the angle?

  • How does autobrake work? Gabriel Brito

    An autobrake is a type of automatic wheel-based hydraulic brake system for advanced airplanes. The autobrake is normally enabled during takeoff and landing procedures, when the aircraft's longitudinal deceleration system can be handled by the automated systems of the aircraft itself in order to keep the pilot free to perform other tasks - Wikipedia How does the aircraft "know" when is time to activate the autobrake systems on a rejected takeoff and landing? Does it apply full brake to all the aircraft's wheels? Is it really used by commercial jets?

  • I'm pretty sure that there are no aircraft equipped with a brake on its nose wheel, however two of my colleagues think there might have been. Are there? Aircraft with retractable gear of course have devices to stop the wheels from spinning when retracted, but I'm asking about brakes used to stop or slow down the aircraft. Please don't consider aircraft with a tail wheel, gliders, experimental aircraft, or aircraft used for flight testing (certified aircraft only).

  • I have a question regarding this Missed Approach Procedure Im in my final approach segment and reach DME 1.1 and the runway is not in sight so I start my Missed approach, how should it be executed? Since I have to hold I'd start a tear drop entry turning to heading 125° and then left turn intercepting 275° course inbound. This option sounds viable to me I first do a right 360° as charted (???) and going to the VOR and then starting probably a parallel entry into the hold. This doesn't sound viable to me Textual description is also clear about that 360° If it 1.) why would they chart

  • There are two sides I've heard when taking off in a Cessna 182 or other small airplane with a normally aspirated engine driving a constant speed propeller: As soon as your wheels are off...), but on the flip side, I've heard that if an engine is going to do something funky, it's probably going to happen when you do a power reduction, or otherwise do something. I personally want all the power I..." as to when you should perform this power reduction (inches off the ground or 700-1,000 feet), and if so, have there been actual studies that say why one way is better than the other, or is this one

  • Let's say you discover that your landing light is inoperable during the preflight. Your aircraft doesn't have a MEL, so you follow 14 CFR §91.213(d). Assuming you do everything else required (placard, etc.), would placing a collar around a circuit breaker be considered deactivation? If not, is there anything that a private pilot can do that would be considered deactivation?

  • The Socata TB-family wikipage lists the TB-9 and TB-10 as having "spatted undercarriage". What does that mean? From the pictures it appears to be a normal tricycle-gear-setup so I assume it's not referring to the layout of the landing gear.

  • These days, when reading news about missing Malaysia Airlines Boeing 777-200, I keep coming across a scenario where pilot might have deliberately turned off the transponder which is used for the communication of flight with ATC. When there is a possibility that any bad thing can happen when pilot turn off transponder, why would one give the ability of turning off the transponder to a pilot when he/she usually depends on instructions from ATC or flight control. Is there anyway that ATC can turn on transponder back from ground?
