    curious lang ako, pano ba napapahinto ang eroplano?
    katulad ba ng sa mga oto/truck na may preno?
    disc break ba or drum, hydraulic, pnemautic?

    sa aircraft carrier, merong cable na sumasabit yung mga airplane.

    sa airport, yung mga airplane ng rereverse engine, makikita mo yung side ng engine bumubukas para magreverse thrust.

    it's a combination of different factors.

    first would be the wing flaps. it is positioned at an angle that will slow the plane's momentum.

    second is the reverse thrust. it blocks the air coming from the engine and forces it to go up and down instead of pushing thru the back thereby slowing down the plane significantly.

    last would be the brakes on the wheels.. dunno what type of brakes though..

    You are the MAN.

    what type of brake? Its a drilled disc brake similar to high performace car but bigger and thicker and equiped w/ anti-lock brake system now using by most cars and trucks. A 747 jet has 9 disc brake.

    Those brakes control by 2 back rudder pedal controlled by pilot feet. If the pilot steps on the top of right pedal, only the rights brakes engaged same holds thru other side. They are assisted by reverse thrust.

    On the Aircraft carrier, jet pilot must bring down his tailhook for the purpose to hook the arresting cable on the flightdeck. If he connect the hook to the cable it will assisted with powerfull reverse thrust and the disc brake similar to those in the commercial jet.

    sa commercial aircraft ...combination of hydraulic brake sa tires, hydraulic flaps down sa wings and reverse thrust sa engine.

    may i just add, ang gulong ba ng airplane e solid or tubeless?

    OT

    Nakakaatras ba eroplano? Pansin ko kasi, yung mga commercial jetliners, may tumutulak pa sa kanila para makaatras lang.

    pag turbo-prop with reversible propellers, yes. yung propeller blade angle can be reversed thereby reversing the air flow from front-to-back to back-to-front. minsan ko pa lang nakita, sa oman desert on a fokker twin turbo-prop. we were at the end of the landing strip (part of the desert that was cleared of rocks) and the plane reversed its props, atras din ang plane. but it did this just to make a u-turn.

    can't do this with a jet because the air intake is always at the front and reverse thrust can never be 100% on a jet engine (more like 30% only)

    Meron akong nasakyan na eroplano sa Amerika na kayang mang reverse ng mag-isa.. American Airlines ako naka subok noon. Yung eroplanong iyon medyo maliit lang baka mga 120+ passengers lang capacity. Merong 2 engines na di kalakihan sa magkabilang side ng dulo ng eroplano near the tail. Tapos pag mag backing na sya, merong flaps yung engine na bumubukas then nagrereverse thrust.

    Ganito ang feeling pag dun ka nakasakay; pag magbabacking na yun eroplano, mafefeel mo na aabante muna then sabay parang biglang aatras pati ikaw mapapa jerk patalikod ng husto sa upuan mo tapos yun na... Atras na sya mag-isa then abante na dun sa runway! (hehehehe)

    parang naexperience ko na ung sariling paatras sa airbus A300 and A320

    yes, MD-80, 82 DC-9 pwede mag reverse thrust depende sa load ng plane and distance of the terminal. Sometimes sa states they use reverse thrust para maka save time and bayad sa tractor tug.

    In that case, if one of them is not working, does the plane can still manage to stop?

    yes sir, if a small aircraft lands in a long runway like in HK they sometimes use brake lang to warm up the landing gears and a little quick reverse thrust...like in HK the runway is 3.8 kilometer long so akala mo smooth landing... you can't do it in Manila

    Di ba 3.7km ang runway ng MIA?

    It can but it needs a longer runway than usual that’s why there were planes that overshoots.

pano humihinto ang eroplano?
