Tornado F 2
In 1987, at EPTS, we exchanged our Lightning T5 XS 422 for a Tornado F2 ZD 935.. Whilst the F2 acceleration at low level exceeded that of the Lightning any hope of level supersonic flight at 40,000 ft was not realised. In the Lightning we could demonstrate the loss of roll rate when supersonic, caused by the shift in cp, whereas the F2 could not get to 1.3 at 40 and sustain a level turn!
