Only three days after the conclusion of the EFTS course, Robert began the most difficult stage of his training thus far. It was at #9 Centralia (which had recently been moved from Summerside, Prince Edward Island) that he passed the Service Flying Training School (SFTS) examinations, but it was not without some difficulty. For four and a half months Robert and his classmates were taught and tested, which aimed to do a final weeding out of any trainees unable to meet the necessary standard.

The SFTS still had a classroom component, which built upon the trainees’ previous knowledge. Many of the subjects remained the same, save for the new additions of meteorology and practical applications of signals and armaments. As already demonstrated, Robert was a strong classroom learner and achieved 81%, which put him in sixteenth place out of fifty-nine pupils.

The new challenge was upgrading to a twin-engine plane. Robert tackled this using a twin-engine Avro Anson, which was of British design and popular for BCATP training. He was tested on the same skills as in a Tiger Moth at EFTS, but now had the challenge of a more powerful airplane under his control. It is clear that most trainees found this upgrade to be somewhat of a challenge, as Robert placed last in the top third of his class with only 71%. By February 1943 he had done a total of 194 recorded flying hours.

While one SFTS instructor had positive comments, the other thought Robert demonstrated nothing more than average skill and recommended that he was not commissioned as a pilot. Fortunately, Robert had enough positive reports on his record to drown out the one negative. He was commissioned with his pilot’s flying badge on February 9, 1943, fifteen months after his initial enlistment.
