A Diamond DA62 was on a pre-arranged training flight for the procedural ILS RW21 at Lydd and on a procedural service from Lydd Information. Whilst established on the outbound leg of the alternate procedure (LZD 360) and in level flight, a good lookout was being maintained by the instructor (front right-hand seat) and another pilot who was an observer on this flight (rear left-seat).
The instructor is familiar with the area and the potential conflict with traffic, so was ensuring a very good lookout, assisted by the accurate flying from the trainee in the left front seat (pilot flying), which enabled a better lookout. The scan was 8sec outside the aircraft, 2sec inside. On the scan previous to the conflict, it was noted by the instructor that no aircraft were visible; however, the aircraft was only 50ft below the cloudbase, which was scattered to broken stratocumulus. Visibility below the cloud was good and 3200ft was being maintained in accordance with the procedure. On looking back out after the 2sec. Both pilots reported VMC but were operating above 3000ft amsl and reported within 1000ft vertically of cloud. They were therefore operating in IMC and consequently under IFR.
scan inside, the instructor observed a glider (HpH 304 Shark S), in what appeared to be a 5° nose down attitude, in his 1 o'clock heading directly at the aircraft, no more than 100-150m away. It appeared to have descended out of the cloud, but may have been hidden behind the uneven base on the previous lookout scan. The instructor immediately applied aggressive forward pressure on the control stick for avoiding action; at the same time the glider banked sharply left. The closest the two came was around 20ft vertically and 10m horizontally. The instructor noted that he was an experienced formation pilot and was used to judging close distances in the air and that the DA62’s TAS showed no contacts at the time.
The pilot assessed the risk of collision as ‘High’.
