Here i would like to put some thing very straight for the record that pervaiz iqbal the captain had been in islamabad since we all started flying .
the way things work is usually hush hush.
I had asked this question on one of the forum that ,would the EGPWS work in case of radar jamming
or
since the bus is fly by wire all the systems work computer in case of a total jamming would the control function.
Secondly we all know as professional pilots that he should nor be there where he was so what made him go there was it am armed intrusion or it a sabotage or simply the radar guidance
those of u who have flown in Pakistan would bare with me it is always a very difficult approach in isb reason the area is so restricted because of prohibited areas
very little one can do
i do agree at the same time the procedure or the airman ship is in doubt
get out from there as for his training for mr mekel he was trained by the pia flying academy
no offence for any, the circling man . is easy to execute in the bus then any ac i have flown
by the way mr mekel i have also flown for the last 43 years BY THE GRACE OF GOD an all the airplane pia as well
the bus most modern
the point to emphasis is not the ac but the simplicity of the procedures and the evolution of the aviation toward the user friendly concept
Having hopefully understood which points you were raising, I'll point out that user friendly for an instrument approach includes the ground based infrastructure. I found a localizer more user friendly on final than a VOR or NDB approach, an ILS moreso. Part of the discussion in this thread is that Islamabad is perhaps, as an airport, user unfriendly due to not having instrument (straight in?) approaches to both runways 30 and 12.
As to radar jamming having an effect on fly by wire suites in modern aircraft, consider this: fly by wire capability is organic to most modern fighters, fighters that are expected to operate in a jamming environment. Do you have any reason to believe that fly by wire in the Airbus is susceptible to jamming? (Do any of the Airbus pilots on this board know of cautions in that area??) Airbus A400M has fly by wire in its design, for military environment. I think you are making some unfounded guesses ... unless you have evidence of jamming or EMI signal source ... is that what you mean by hush hush?
EMP is another matter, but why would it be related to this case? What about the crash would lead one to consider that?
EMI is another matter (did a bunch of passengers all turn on their remote electronic devices?) and I'll let that guess sit for a moment. What evidence is there to support that causal factor?
If EGPWS was to be jammed (what, jam the radar altimeter?
) how would one know? How would one do it, given how radar altimeters work? I think you are fishing, and I think this idea is a red herring.
Sabotage or armed intrusion ... the CVR data might help analyze that odds of that. Guessing again?
Lastly, on radar jamming, if one is executing a circle to land, a visual procedure, how would radar jamming influence you since you are not using radar cues to fly?
How thoroughly have you thought through this?
