Maybe at Larger airfields this is correct Ghengis but we have never been required to confirm the status of a training aircrafts gears as they are usually "down & fixed" which you must only confirm to "YOURSELF" While performing pre-landing checks, Also i was once taken up in an aircraft with retractable undercarriage and we werent asked to confirm the status of the gear then either, Leeds-Bradford isnt the biggest of airports & only accepts aircraft up to around the B757 size, (VARY RARELY) , Most often Fokker 50's & Boeing 737's. So maybe its the size of the airfield that sets the requirements for radio procedures such as reporting the Gear status????
