V-22 Brake/Park Brake Description seems reasonable. What are the issues for MROL (apart from more testing required). Seems to me a CVF will provide sufficient deck length for braking (subject to further US testing).

"...The hydraulic brake master cylinder functions as a boosted brake valve assembly when the aircraft hydraulic system is pressurized. The unit directs flow and pressure to the wheel brake cylinders.
The brake pressure delivered is a function of pilot input force, which is proportional to the brake displacement. When there is no system pressure, the unit reverts to manual braking, utilizing a two-stage piston arrangement.
The Sterer brand park/lock valve provides isolation of fluid between the pilot and co-pilot's master cylinders and the brakes. It also has a lever and poppets so that when actuated, hydraulic pressure is locked in the brakes for parking. The unit contains free maintenance accumulators to provide fluid for thermal compensation when the unit is in the "park" mode. Pressure switches are incorporated in both the right and left brake pressure indicators...."

"...-The V-22 has difficulty remaining parked on rolling aircraft carrier or assault ship decks.
Correction: This is not true. Initially there was a problem with the parking brake when the aircraft were moved on deck because the brake rider in the cockpit needed improvement. This fix was made in three of the four aircraft that were used during the recently completed Operational Evaluation and in all production aircraft since...."
