Narrative:
On the first leg of the sequence; during climb out at approximately FL210; we were cleared present position direct ldn then fpr. Captain was flying and said 'you have the aircraft.' I said 'I have it' and he began making a PA to the passenger. I thought the autoplt was engaged and was monitoring the progress of the trimmed aircraft during its climb. When we reached ldn; I saw the flight director indicate the turn; but noticed the aircraft was not turning. I then noticed that the autoplt was not engaged and took manual control and made the turn. ATC called to ask us our heading and I reported that we had overshot ldn and were correcting back to the outbound course. I saw 7.4 DME from ldn at the widest part of the turn back to course. Upon query to ATC; they reported that there would be no further action required and we continued on the flight without incident.
