Security searches are carried out on all passengers and baggage before they’re allowed to board the aircraft.
This includes searches of disabled people and mobility aids.
If you’re wearing headgear for religious or cultural reasons, you can ask for it to be checked using a hand-held scanner so you do not have to remove it.
You can ask for a hand search if you have an implantable cardioverter-defibrillator (ICD). You should carry your ICD identification card with you when you travel. Scanning devices and metal detectors should not cause a problem, though the metal detector should not be placed over your ICD.
You can also ask for a hand search of hearing aids. You should bring a letter from your doctor stating why they should not be scanned. However, it is up to the airport to decide if they need to be scanned or not.
