No 'A1' or even 'B2' QFI would ever stoop to such utter rot! During Climbing and Descending, the student is taught to LOOKOUT, maintain the correct ATTITUDE and then to verify that the correct attitude has been achieved by brief reference to the INSTRUMENTS appropriate at the time. In straight climbing/descending flight, these instruments are the ASI, DI and ball, with ocasional reference to the altimeter. No 'special mnemonic' is required; however, occasionally the additional brief scan of Ts and Ps is required, as is a positive 'clearance' of the flight path by a small turn to clear the area hidden by the engine, but NEVER by 'lowering the nose' (or even selecting, holding and trimming a lower pitch attitude as real QFIs would say).
'DABLE' = drivel!
