Technical Delegate's Report Before the race:
Components of all cars were checked and compared with the information supplied by the relevant
team's Used Inventory Incremental List (UIIL).
The spare front corner of car numbers 31 and 10 was digitally scanned and the scanned data were compared with the team declared CAD drawings. Further the team declared CAD drawings were
also compared with previously submitted versions and checked for conformance with the 2023 Formula One Technical Regulations. The front wing adjustability of car number 55 was digitally scanned and checked. The spare left rear corner of car numbers 77 and 24 was digitally scanned and the scanned data
were compared with the team declared CAD drawings. Further the team declared CAD drawings
were also compared with previously submitted versions and checked for conformance with the 2023 Formula One Technical Regulations. Clutch paddle linearity checks have been carried out on cars 11, 55, 44, 10, 4, 77, 24, 14, 20, 40, 23 and 02.
A front floor deflection test was carried on car numbers 63, 20 and 40. The uppermost rear wing element adjustable positions were checked on car number 40.
The minimum distance between the adjacent rear wing sections at any longitudinal vertical plane was
checked on car number 40.
On the grid it was checked that all cars had fitted their tyres and the tyre heating blankets were disconnected, when the "5-Minutes" signal was given.
On the grid the temperature of the LHS and RHS front and rear tyre was checked on car numbers 01, 11, 16, 55, 63, 44, 31, 10, 81, 14, 20, 27, 40 and 23.
