A friend of the passenger who landed a plane after the pilot was taken ill said he was "nothing short of a hero".
Richard Tomlinson, who was also a friend of the pilot, told BBC Radio Sheffield, "For somebody who is not a pilot but has been around airfields and been a passenger on several occasions to take control is nothing short of phenomenal."
Mr Tomlinson said the man who died was a very experienced pilot.
He continued: "Only this week I was sat having a cup of tea and airfield banter [with both men].
"They were both very funny gentlemen to have a conversation with. "It is very, very sad news."
The post mortem of a pilot who died after falling ill at the controls of his plane is expected to take place tomorrow afternoon, Humberside Police have said.
Police are not treating his death as suspicious "at this time" and the results of the post mortem will determine whether an inquest is necessary.
"In accordance with the wishes of the family of the deceased, police will not be confirming the identity of the pilot nor releasing any video footage of the incident," a spokesperson added.
The pilot of the light aircraft who became incapacitated while flying back to Sandtoft airfield during the evening of Tuesday 8 October resulting in an emergency landing at Humberside Airport was sadly pronounced dead last night.
Police are not treating the death as suspicious and as such a file will be prepared for the coroner in order to establish what led to the death of the pilot by way of an inquest.
Formal ID of the pilot is likely to take place later today.
A pilot who fell ill at the controls leaving a passenger who had never flown an aircraft before to land the plane has died, Humberside Police said.
Emergency services gathered at Humberside Airport, north Lincolnshire, on Tuesday evening after a passenger in the light aircraft had to land it with the help of two instructors from the ground, an airport spokesman said.
A passenger who had never flown an aircraft before has been praised for making a safe emergency landing after the pilot became ill and unable to operate the controls.
Roy Murray, one of the flight instructors who helped the passenger land the plane from the ground, told the BBC the passenger had no flying experience and did a "remarkable job".
He said the passenger made quite a good landing in the circumstances, considering he had never flown a plane before and was "flying blind".
Mr Murray said: "It's a fantastic feeling, knowing I have achieved something and probably saved somebody's life.
"I think without any sort of talk-down he would have just gone into the ground and that would have been the end of it."
A plane passenger who made an emergency landing after the pilot became ill and was unable to operate the controls "sustained no injuries", police said.
The passenger in the aircraft sustained no injuries. The exact condition of the pilot is not known at this time.
The police investigation is now underway. However, it is too early to speculate as to what caused the pilot to become incapacitated.
Humberside Airport said the "major emergency" caused when a pilot fell ill at the controls of an aircraft has been "successfully dealt with":
We are pleased to say that the incident that started a few hours ago has been successfully dealt with.Great response from emergency svs!
