The son of Leicester City owner Vichai Srivaddhanaprabha has thanked people for their "overwhelming support" following his father's death.
He said he would now try to carry on his father's "big vision and dreams".
Mr Vichai, two members of staff, the pilot and his partner all died in the crash outside the King Power Stadium.
On Monday, Aiyawatt laid a wreath with his mother and Mr Vichai's wife, Aimon, outside the stadium, where thousands of tributes have been left by fans and well-wishers.
A book of condolence has opened at the ground to those who died and buildings have been turned blue in tribute.
In a statement, Mr Vichai's son thanked people for their kind messages on behalf of the whole family, and the emergency services for their response on the night of the crash.
He wrote: "What happened made me realise how important my dad was to many people all over the world and I'm touched by how many people have kept him close to their hearts.
"From him I have received a very big mission and legacy to pass on and I intend to do just that."
