Amen
I've learned a lot from your analysis and that of Sandee.

manny4life: Some key parts to review



Question to this part, since there was no call out, did the Pilot (captain flying the aircraft), start rotating after the 80knot call out?

joe_ekuns:


How can you say that? Even if he was suspended for 5yrs or even threatened of being fired is it enough to put his life or other's in danger Haven't you heard the saying when there is life there is hope?

baybiemee: And a heartless fellow said it was an act of God

Tintinix: ....And Stella Oduah should resign because of a blatant disregard for safety warnings!!!!!!

ndu_chucks: In Nigeria, even the blackbox recording can be doctored for political gains. Don't let them put the wool over your eyes. No sane pilot will risk his own life by ignoring such a warning and take off anyway, unless he is a kamakaze pilot. Nonesense!!

ba7man: Enforcing safe practices in Aviation is far more important than analyzing a Black Box in Nigeria.

If there are no Plane crashes, there won't be Black box analysis. Why walk through Refurbished Airports to board rickety, unsafe Planes??

moscobabs: so who 1st die now??

manny4life:


You know exactly what I meant, unless you're trying to pick my exact words. Flaps cause drags as well as help in generating lifts at slower speeds.

Like I was thought in ground school, thrust DOES NOT generate lift, thrust is the power (N1 and N2) that generate power which propels the aircraft forward direction causing enough airflow over the wings, with a little curvature from the flaps, causing the aircraft to lift when you pull back on the controls.

When you talk about pitch/yaw, that's the elevator/rudder controls, that's something totally different.

Thank you

So the pilot paid less concern abt d life of his passengers and decided to gamble wit it. He is think that there was were planestops in d air where he would park d plane if it breakdown? Its just that u can't sue d dead I would ave said d families of those decease should sue but RIP to d dead.

Point of correction, flaps do not generate lift, it's just part of an aircraft control surface used for pitching. All lift comes from the thrust that is being generated by the engines.

In this scenario, both the inability of the flaps to deploy and the lost of power from one of the engine lead to the crash. If I should analyze what happened, the pilots took off from the run way pitching the plane at a wide angle of attack (aoa). However, when it's time to pitch down or reduce the angle of attack of the aircraft after the pilot might had completed the ascension stage, the flaps developed faults. Moreover, the lift-to-drag (L/D) ratio tends to be very low at the end of ascending stage, which if not properly control will stall the aircraft, i.e. the aircraft will loose lift not matter the thrust the engine is producing.

To cut all the technical jargon, at the end of the ascension stage, the pitch was high (wide angle of attack) and the flaps used for controlling the pitch developed fault, the aircraft stalled due to low L/D ratio and came crashing down.
I disagree 100 percent,flaps do not control angle of attack,flap generate additional life.they re called lift augumentin devices,they re used to generate lift at low speed so ur aircraft can av a shorter take off and a lower landin speed

You again Sir, have your head in the right place. Too many wannabes commenting based on little they know and claiming to be experts

I think we all agree that not engaging the flap in of itself is not enough to cause a crash, all other things being equal. We are told that the crew decided not to use the flap during takeoff. It seems to me as if the real cause of the crash is the following as noted in the AIB report:

By the way i tell u to ur face u are talking nonesense; absolutely bullsssssssssssssssss! Useless opposition that will never see anything good; useless opposition that tell us the timing of SNC is bla blah

who told u thrust generate lift; so why then plane got wings; ehh? make una hold me for nl; i go break bottle for una head one day!the air flow under the wing is slower than top of the wing; the extraction and elevation of the flap can either compress more air under the wing or reduce then lift is generated.

now next time u are on board make sure u sit near the window; then take note as take off incidental happens as the flaps are almost fully extracted but as soon as the plane reaches its flying altitude then watch as the flap are retracted!

now question; do u still call for resignation after this

VULCAN: Very interesting discussion between manny and ndu chuks. I was hoping to hear from more pilots(especially commercial) and aeronautical engineers so that we could get a even more rounded perspective on what happened. Thanks to Anyanwu for shedding more light on this.

But it seems that manny and ndu chuks are attempting to blame pilot error or lack of airworthiness respectively as the cause of the crash. Who said that it had to be mutually exclusive? It appears to me that it was a mixture of both. Eyewitness account by Feyi and his in-law said the plane was in a very poor state and the discussion in the cockpit(which AIB alluded to but refused to elaborate on) gives credence to this.

And where are the Nigerian nairaland pilots and engineers? Seems there are so few. Sad. Just like the Dana crash thread. It was a foreigner who came on the thread and was a friend of the dead pilot that gave a clear idea of what might have happened.

As to some asserting that the speed of the preliminary report's release is too fast- I would like to say that the voice recorder is just a tape that records conversations just like our phones and mp3's so what's the big deal? Even a child can listen to a conversation and report it within 5mins. Analyzing the Data Recorder is where the real work is. That will take much longer and requires real expertise.

You Sir, this is one load of tosh! Arrant Nonsense and a complete trash smiley

Now can We go back to the AIB report, though preliminary, perhaps we can deduce 2 and 2 to make a 4 wink wink
