1. An aircraft system for an aircraft, the aircraft system comprising a controller that is configured to:
receive at least one non-simulated signal during a real landing procedure of the aircraft;
determine that the aircraft is at a predetermined stage in the real landing procedure prior to touchdown of the aircraft, on the basis of the at least one non-simulated signal, wherein the predetermined stage is before a command to extend at least one landing gear of the aircraft is issued during the real landing procedure;
on the basis of the determination, and before the command to extend the at least one landing gear of the aircraft is issued, causing the aircraft system to initiate a first part of a procedure to interrogate an aircraft braking system, on the basis of the determination; and
in response to the issued command to extend the at least one landing gear of the aircraft, cause the aircraft system to initiate a remaining part of the procedure to interrogate the aircraft braking system, the remaining part to be performed after completion of the first part,
whereby initiating the first part of the procedure to interrogate the aircraft braking system before the command to extend the at least one landing gear is issued causes the remaining part of the procedure to interrogate the aircraft braking system to be initiated after the command to extend the at least one landing gear is issued and thus to be completed before touchdown of the aircraft.
