Three brothers who died in RAF service have been remembered with the unveiling of new planes bearing their names.
The Aquila aircraft are dedicated to Alasdair, Roderic and Iain MacRobert who all died in their mid-20s, two of them during the Second World War.
The three planes have been named 'Spirit of Sir Alasdair', 'Spirit of Sir Iain' and 'Spirit of Sir Roderic'.
A fourth plane was also unveiled at Tayside Aviation in Dundee in memory of Flight Sergeant Donald Jeffs, who survived a crash in a memorial plane commissioned by the men's mother, Lady Rachel Workman MacRobert.
Flight Sergeant Jeffs was held as a Prisoner of War after crashing in Denmark in 1942 but went on to live a full life until he died in 2017 at the age of 98.
The planes will be used to teach cadets how to fly.
Every year, Tayside Aviation trains around 200 RAF cadets, with many going on to become pilots or officers in the RAF or Royal Navy.
Managing director Jim Watt said: "We are honoured and proud to be unveiling these four aircraft which tell an important story of selfless bravery, sacrifice and resilience, which we are keen to keep alive in the minds of today's cadets.
"Although the RAF has continued to carry the MacRobert Crest on a bomber, the names of the three sons have all but disappeared so we felt that it would be a fitting tribute."
