April-May
The team moves overseas, to perfect their display in the better weather conditions of Greece or Cyprus. This is known as Exercise Springhawk. Shortlist week also takes place here – where pilots hoping to get a place on the team are assessed. The training season ends in May when the Red Arrows’ Air Officer Commanding makes an assessment of their safety and professionalism. If he is content, Public Display Authority is awarded – permission to display in front of the public. The pilots, engineers and support staff are now allowed to wear their red and blue flying suits.
