Teoh Z Yao 0 Report post Posted January 12, 2007 Read this on a.net and enjoyed the f/o's account. He claims confidently it was cellphones' fault. How true is that, the pilots? well here is another one of my famous cell phone stories, this time it got bad.... Flight TK 459 from ADA-IST - Captain's leg for flight. The weather at ADA was CAVOK we were using runway 5 for departure and we got to rolling, all systems normal and take off thrust set itself just fine on autothrottle.... then after my V1 call and rotate we took to the air and everything was good too, then the drama starts... at 400 AGL we are required to select a ROLL mode, i selected Heading for the captain, as we were cleared on runway heading, however it didn't engage, the mcp didn't light up or the FMA or the F/D bars...nothing....so i tried putting on LNAV, same thing.....we continued manual...then at 1000 i tried to engage the A autopilot...that did nothing...B, that did nothing...then at 1500 I tried to reduce to climb power by pressing the N1 button...nothing, tried changing the MCP speed, didn't budge....at this point departure cleared us to MUT vor after 3000, so the captain was flying full manual turning the a/c while the F/D were telling him to continue his heading, started getting confusing.... then passing 7600 feet while climbing to level 260, we asked the Chief F/A to do a cell phone check in the back...she came back with no results....we were slightly shocked....then we were able to put in autopilot A but when it engaged, the VNAV AND LNAV came on all by them selves and the plane dove downwards a little, and then autopilot kicked off.....she started going insane, level change came on by itself, and it pulled the speed back to 171 knots with the flaps up while we were doing 284 so she started climbing at 4500 feet per min, im sure people noticed at the back that something was kinda wrong....i didn't enjoy it....then both EADI flight directors disappeared completely, and the FMA locked on VNAV and LNAV, and the aircraft was telling us to turn in a completely useless direction, the captain kept her in manual, now passing 22,000 feet we were utterly confused, the checklist had nothing, we couldnt use our FMS LNAV and the aircraft was being crazy, then several seconds later i was cross checking the 3 airspeed indicators like MAD because i had no idea which FCC was engaged versus which was we selected and what the damn plane would command us to do....i tried autopilot A again (to reduce the workload so we could problem solve together) it engaged! however, 10 seconds later it kicked off...because...and im glad this didn't happen in IMC...the Captain's EADI flight director was asking for a 20 degree nose dive, and my EADI F/D was commanding a 20 degree nose UP attitude....we just looked at each other....., the altitude warning horn went off at random intervals...and the stress level was a lil higher than usual because we know VERY well flying the -400 that someone's friggin cell phone is on back there, that's the ONLY thing in almost 10 years of TK history that messes up the MCP panel, coming from experienced captains... so the pre recorded cell phone announcement was played FOUR times, and nothing, then we asked each one of our cabin staff to basically violate people and find the phones..... guess what.....5 cell phones were on, 2 were text messaging, and one person was playing music and looking for a cell phone tower at altitude to see if it kicked in or not....pax were furious, because we were heading to CAT II airport at the time and we needed these damn instruments for the approach into IST.... once those 5 cell phones were switched off....everything came back to normal, both autopilots came on when we selected each one, all F/D indications came back, the FMS was usuable and nothing went wrong again.... i can't tell you how friggin upset i get, people always pray that we fly safe etc and oh i hope god watches out for you etc...but then they try to use their cell phones...can you believe someone was trying to text message that they were in the plane right as we rotated? don't you just wanna beat these people up?

Edwin P K 0 Report post Posted January 12, 2007 Doubt so, I don't know much about cellphones, and how it interferes, but if it really interferes, cellphones should be banned altogether (ie not allowed entry into the plane) Share this post Link to post Share on other sites

How about those who don't check in baggages? What's your idea? Share this post Link to post Share on other sites

Hakan 2 Report post Posted January 12, 2007 hmmm very interesting report. ADA is Adana Airport which is one of biggest and domestic trade center in middle of Anatolia.So, there is one of domestic carries major destination. Anfotunately, Adana peoples are not fully educated according to other 3 major Turkey big cities. Not the same but likes passangers problem can be getting in anatolia flights in Turkish carriers by uneducated peoples. Past years while I was flying as a passanger with THY, I was disputting to some other unresponsbile passangers sometimes about regulations! Generally, cell phones negative effects were not prove yet excatly. Specialists says, "this is a higher possibility but nıt means every cell phone can be disengage aircrafts navigsiton and autopilot systems but in depends on devices type or frequecy wave power." In my opinion, I believe cell phones excatly gives negative effects on aircraft navigation systems with their frequency transreceiver capability. As you know so many antennas located under passanger section on fuslage and also some of navigation devices located near cargo bays too. I'm not support cellphones "flight mode" special for listening MP3 or etc. cellphone is cellphone and no one can't give me a gurantee to anyone does not open phone instead open "flightmode" for mp3 or anything! 5 cellphones is really serious problem for older 737-400.new aircrafts have advanced and isolated antennas but -400s are a bit older for this new technologies. But I'm very angry to another point; why other passangers did not warn to unresponsible passangers!!!!!! I'll forward this report to my Turkish forums or taking attentions to cellphones use.

razlan 0 Report post Posted January 12, 2007 (edited) And phones will have to be stocked in the cargo area (in check-in baggages), right? How about those who don't check in baggages? What's your idea? any equipments that interfere with aircraft navigation/handling should be banned, period. I hv a pda phone with offline/flight mode but still switch it off - not going to be the caused for other people misery/death. what the airline/airport can do is request the pax to handover the equipments to f/a before boarding the aircraft and return it back upon reaching the destination's terminal. Is there any scanner that can scan for cellphone etc? this can be used to any pax who refused to co-operate. Edited January 12, 2007 by razlan Share this post Link to post Share on other sites

Damian 0 Report post Posted January 15, 2007 hmm interesting report..the worst thing that i've experienced similar to this is that the a/p disengages when i press on the a/p B when we try to engage a dual autopilot approach..or VNAV refuses to engage when u press the button on the MCP..but these senarios have no all-too-serious implications other than an entry into the MR1.:-) well since it wasnt IMC,i guess they could have told ATC to RTB and request for a visual app or fly the instrument app completely raw data without all the fancy instruments and autopilot..they would have to ignore the F/D command bars if they have gone crazy..
