(c) Oil pressures
Normal at 7,600 r.p.m. 35 lb./sq. in.
Minimum at 7,600 r.p.m. 25 lb./sq. in.
56. Flying limitations
(a) (i) Intentional spinning is prohibited. Stalling practice is not to be
carried out below 25,000 ft. nor continued beyond the buffet stage.
(ii) RP's may be carried and fired, with or without drop tanks fitted
on the inboard pylons. The maximum diving angle during RP
firing must not exceed 60°.
(iii) When carrying external stores, other than empty inboard drop
tanks, practice selections of Manual must not be made since the
presence of stores increases the difficulties of reselecting
Power. Gun ammunition must be carried to maintain the CG
within reasonable limits during take-off.
