What is VMO (maximum operating speed) of the aircraft expressed in KCAS?

Explanation:
VMO is the maximum speed at which the airframe is certified to operate in normal conditions, expressed as indicated airspeed (KCAS) to reflect structural loads at lower altitudes. For the P-8A Poseidon, the published VMO is 340 KCAS, which sets the upper limit in the normal flight regime; above a certain altitude, the limit transitions to MMO (Mach number), typically around Mach 0.82. This means you should not exceed 340 KCAS in normal flight—doing so would push past the airframe’s approved handling and load limits. The other options would either unnecessarily constrain operations (lower than the published limit) or exceed what the aircraft is certified to handle (higher than the limit).
