Vakakaaa,
FYI...
These were the official statements coming from Alyoshin:
While investigators began their work, Lieutenant General Alexander Alyoshin, deputy head of the Russian air force, revealed that the pilots of the ill-fated airliner had repeatedly ignored instructions from air traffic controllers.
Wreckage -- including the engines and a large chunk of mud-caked tailfin -- was scattered across a forest. While sections burned for more than an hour, the black-box flight recorders were found, news agencies reported.
Some 1.5 kilometres (one mile) from the airport, air traffic controllers noticed the Tupolev -- overhauled in December 2009, according to manufacturers Aviakor -- was below its appropriate glide path, Alyoshin said.
"The head of the (air traffic control) group ordered the crew to return to horizontal flight, and when the crew did not fulfil the instruction, ordered them several times to land at another airport," he said. "Nonetheless the crew continued to descend. Unfortunately this ended tragically."
As was stated in the first interrogation, the ATC stated they could see the aircraft. This contradicts the second interrogation where ATC stated they did not see the aircraft on the radar.
And you are correct, the radar is important, that is why the Polish prosecutor is requesting information from the Russians, on the radar.
From another aviation forum... (google translated)
Re: When approaching the 3 or 4 a reversal of decline often asked the current altitude, as if you see any bad or just clarify for control.
ИМХО, поправьте меня, но я для себя всегда этот момент связывал с боковыми лепестками диаграммы направленности локатора.
IMHO, correct me, but I for myself always, this time connected with the side-lobe locator.
То есть, у любого локатора есть свои точки неустойчивого приема.
That is, any radar has its own point of unstable reception.
Хотя в данном случае скорее всего речь идет о каком нить радиодальномере.
Although in this case most likely it comes to what the thread telemeter.
На посадочном таких нюансов никогда не было.
At the landing of such nuances never had.
Что позволяет предположить скорее об особенностях использования того или иного локатора или радиодальномера, нежели о его неисправностях.
Suggesting that most of the peculiarities of a particular radar or telemeter than its faults.
Это один момент.
This is one thing.
-----------------------
На аэродроме Северный был установлен военный комплекс РСП-10.
At the airport the North became a military complex of the CPR-10.
Это диспетчерский и посадочные локаторы в одном вагоне.
This tower and landing radars in the same car.
На больших дальностях от 200 км до посадочной прямой ведут по обзорному диспетчерскому локатору.
At large distances from 200 km to the final approach led by the review dispatching locator.
У РСП-10 нет международного вторичного канала RBS а только отечественный УВД (как в гражданском ДРЛ-7СМ), все ТУ-154 сейчас летают с ответчиком в режиме RBS, поэтому диспетчер не мог видеть высоту борта.
There is no CPR-10 international secondary channel RBS only domestic air traffic control (as in civil DRL-7cm), all of the TU-154 is now flying with the defendant in the mode of RBS, so the manager could not see the high side.
Только азимут и дальность по пассивному каналу.
Only the azimuth and range of the passive channel.
В ближней зоне в локаторе обычно используется режим селекции движущихся целей.
In the near zone in the locator is commonly used mode of selection of moving targets.
Не буду вдаваться в подробности, но в районе третьего четвертого разворота и при пролете траверза РЛС из-за особенностей режима метка от ВС пропадает на 2-3 оборота антенны.
I will not go into details, but in the third and fourth turn during the flight abeam the radar of the peculiarities of the regime tag from Sun disappears for 2-3 turns the antenna.
После выхода на посадочную прямую используют ПРЛ из состава РСП-10, напоминающий РП-4Г.
After landing on the direct use of PRL from the CPR-10, reminiscent of the ER-4G.
У диспетчера есть индикаторы курса и глиссады, по которым он контролирует положение на посадочной прямой с высокой точностью
In Manager there are indicators of the course and glide path, on which he controls the situation on the final approach with high accuracy.
Alice025,
Have any of the pilots that you have spoken to talked about RSP and CAP for Smolensk?
Also there is a terminology "mode" and "planting"...
10:37:26,2 D 101, follow the fourth.
10:37:23,1 KBC and carry out the fourth, Poland 101.
10:39:08,7 D 101-th, removing 10, the entrance to the glide path.
10:39:30,1 D 8 at the course, glide path
10:39:33,6 KBC undercarriage, flaps are released, Poland 101.
10:39:37,3 D band is free.
10:39:40,8 D Planting additionally 120-3 meters. 10:39:40,8 Д Посадка дополнительно 120-3 метра.
10:39:45,6 KBC Thanks.
