    1.   Pls why do we perform NTS checks on the C130?

    2.   Why do we place the NTS/Valve switch to NTS before engine shutdown

    To check the serviceability of NTS system in every post flight shutdown.  Three position SW is selected to NTS position before shutdown of engine because the system must  be checked either it is serviceable for next flight or not.

    I think output starter RPM is 8250 approx. Regard

    Just assume that  your engaging the starter in flight ,at  what RPM Turbine of starter  is revalved?

    Sir my question is which RPM u wanted to know.... I means RATED... NO LOAD CUT OUT or OUT PUT rpm??? Bcoz these all are different

    Dear muddasar What is the 100 % RPM of ENG Starter?

    Job guides are there for fault isolation..... Ok fine with the throttle anticepation but my question is how probkem shifted to other engines if the problem was with NTS BRACKET itself... 

    Moeed Hussain Sb GS/JG/FI/FR are familiar with them, how to coordinate FR with FI

    Pjvr99 do u know what actually happend in this case???? Look dear as mr. Muneer is saying problem shifted to No. 4 and No. 1 respectivly..... So NOW THE QUESTION IS IF NTS BRACKET WAS FAULTY THEN Y IT SHIFTED TO OTHER ENGINES???

    No doubt NTS may also b the reason but only for one engine not for all. 

    Dear moeed as you that what is synchrophaser stabilizing mode and throttle anticipation. Please consult T.O IC-130B-2-11. How NTS system  works?

    Dear munir abbasi sir.... Can u plz tel me how ignition occurs??? Dear i means ignition is self sustaind.. Once ignited it wil remain self sustaind and if one of your ignitor plug is working good i think it will b enough to ignite the fuel air mixture.... 


    Dear  Moeed,are you aerodynamic engineer/mechanic , Thermodynamic engineer/mechanic and FE ,please  contact me muhammadmunir332@gmail.com

    Dear during landing portion PL remain much vigilent for these flying FOD.... but once PL reaches his final aproach and landing speed after this it is much difficult for PL to avoid these... So in my opinion it is the duty of mobil as well as ATC to clear enviroment from birds near the landing points....

    I disagreed with this.....  Explain how the ignitor plugs are the defaulters in this case??? REGARDS... 

    Dear Moeed as you know that one of ignition plugs became defective what happen in flight one plug unable to ignite the rich mixture but on ground you can not judge.The pattern of mixture is changed as enrichment switch is  selected to normal.

  10. Hello world Flyer expertise ,how PL can avoid bird FOD while landing and takeoff. My opinion is, the  vision of PL is   like eagle vision ,bird FOD can be avoided during LDG and T/off

    Not much to be done there. Airfield safety should be taking care of birds thru keeping grass verges short, falcons, etc. Nothing a crew can do

    once they're committed to land or take off


    Thanks petter

    Struggling with an ongoing ATM gen problem. Getting good freqs good volts. Turn ATM gen to on gen out light does not come on but the ESS bus off lite stays on and all systems requiring 3 phase power do not work. 


    The single phase AC items on bus do work. AC instrument fuel control bus works and Elevator trim works. 

    We have changed contactor, generator, GCP, and voltage regulator multiple times with no luck. Anyone seen this??




    Have check battery was connected and  SW solenoide CB push in? EXT power contactar is not de-energized , check the K9 contactor

    Are you performing vibration analysis, prop balancing, torquemeter runout, 135 day signature checks with Honeywell VXP equipment? vibration maybe the key.

    Thanks T56 GUY

    Thanks a lot for your answer "Hehe".

    My concern is with potential significant ice accumulation under severe icing conditions and potential flow "disruptions" in front of lower pitots tubes (static pressure error ?)  with AoA for exemple.

    What beautiful picture of B model aircraft

    Thank you. based on this and your previous mentioning the shift

    to another engine, it sounds like you have a rollback, a problem

    with the synchrophaser. Check out synchrophaser, sych rack, and

    also run synch box tester. sometimes the problem can be a false

    signal generated by a seemingly good valve housing. also check

    all 4 prop pulse generators.

    is this in level flight, during a ground run, taxi, descent, take off? what are throttle sttings?

    Throttles are in takeoff range on the ground, aircraft lineup in the runway for departure
