Explanation

Reliability is most critical for an aircraft in flight because a system that fails mid-air cannot simply be taken offline or restarted - loss of reliability can be catastrophic and irreversible. Availability (B) matters greatly on the ground for scheduling and operations, but an available aircraft that fails in flight is worse than useless. Manageability (C) relates to ease of administration and control, which is secondary to the system actually functioning correctly. Maintainability (D) concerns how easily a system can be repaired, but maintenance happens on the ground - not at 35,000 feet.

Memory tip: Think "RAAM" - when something cannot afford to fail mid-mission (aircraft, pacemakers, nuclear reactors), Reliability always wins. Availability and Maintainability are pre/post-mission concerns, not in-flight ones.
