Mumbai: Boeing aircraft manufacturers recently issued airline-specific bulletins warn pilots for a long list of possible cockpit problems can be surrounded with in lowlands if 5G signals from the transmission station near the US airport have occurred hazardously to disturb people from a plane that instruments Accurately measure the height of the plane on the ground.
Air India, the only Indian operator that flew to the US, operates a route with a wide-bodied boeing aircraft.
Other aircraft manufacturers have also issued the same document, but the 5G effect varies.
For example: Airbus Country documents: “On the A350 and A380 aircraft, 5G interference with altimeter radio can be ignored, there is no cockpit effect.” A senior B777 commander said: “Boeing has registered everything that might be wrong in the cockpit if 5G disruption has ever happened.
Pilot Message Getting is not to try a low visibility landing, radio altimeter is not reliable.
Also, when landing in good weather, stay extra alert after falling 2,500ft and ready to land the manual.
” Boeing 777 Senior Commander, which originated from India Pilot Guild, Indian Air Union with the B777 pilot member, said: “About eight of the 10 pilots will never face one of the situations listed in the bulletin.
As long as the engine works and runway is in sight, there should be no problem.
” What all pilots agree is, with 5G launch in the US, the workload in the as-bound aircraft cockpit has gone up.
For example: at a height below 2,500ft, the pilot will now have to be aware of the possibility of 5G disorders.
Boeing instructed them to monitor and cross-check between two different altimeter readings.
Above 2,500ft, the barometric servo altimeter provides altitude information by reading the difference in atmospheric pressure.
This is not affected by 5G waves.
Under 2,500ft, the aircraft and pilot systems rely on the reading of a more accurate altimeter radio.
But if 5G wave interference occurs, the radio altimeter can fail or provide the wrong reading, said the bulletin.
Captain Amit Singh, an air safety expert, said: “At very low temperatures, reading barometric altimeter is inaccurate.
Now, the radio altimeter reads too is suspected because of the possibility of 5G disorders.
So how can cross-check occur between two unreliable sources? ” Low temperatures can also present low visibility conditions when approaches and landings such as CAT-III – ‘blind’ landing is carried out by depending on aircraft instruments and land navigation aids – done.
A 5G wave interference can cause missteping the altimeter radio entered into the aircraft system.
So ‘autopilot’ function that he-LP carry out low landing visibility can fail, said the bulletin.
The system that pilot warning to another plane on the Cou-LD collision path failed a warning.
The system that gives a warning on approaching Terra-in and barriers may be made not operating or functi-on mistaken.
Captain Singh said: “During training, pilots were drilled to trust aircraft instruments to prevent spatial disorientation during low operation visibility.
With 5G, this instrument is suspected.
In addition, there are special instruction sets given in the bulletin.
From human factors / performance perspectives are difficult tasks that will add workload and stress.
” Captain Sam Thomas, Director (India) of the International Federation of Air Line Pilots Association, said: “What needs clear information pilots and clear risk mitigation procedures.” He added that evidence-based study needs must be carried out before comprehensive comments can be made.
Captain Mohan Ranganathan, an air safety expert, said: “One more reason for the pilot to not be complacent with automation.
They will need to have a manual flying ability.
