  MOCA along the airway is 2,700 feet and MEA is 4,000 feet. The aircraft is within 22 NM of the VOR. The pilot should remain at 2,700 feet until crossing the VOR because that altitude ... minimum IFR altitude for the route segment being flown. 3. The MEA between a and b: 5,000 feet. The MEA between b and c: 5,000 feet. The MEA between c and d: 11,000 feet. The MEA between…

  pilot is expected to comply with the crossing altitude as a provision of the clearance. Any other clearance in which pilot execution is optional will so state “AT PILOT’S DISCRETION.” EXAMPLE-1. “United Four Seventeen, descend and maintain ... commence descent upon receipt of the clearance and to descend at the suggested rates until reaching the assigned altitude of 6,000 feet. EXAMPLE-2. “United Four Seventeen, descend at pilot’s discretion, maintain six thousand.” NOTE-2. The pilot…

  Chapter 8: Flight Instruments › Altimeter Operation

  altimeter indicates an altitude above the actual field elevation. If the barometric pressure setting is reset to the current altimeter setting of 29.68 "Hg, then the field elevation is again indicated on the altimeter. This pressure change ... easily noticed in flight since aircraft fly at specific altitudes. The aircraft steadily decreases true altitude while the altimeter is held constant through pilot action as discussed in the previous section. Knowing the aircraft’s altitude is vitally important…

  Descending From the En Route Altitude Making the transition from cruise flight to the beginning of an instrument approach procedure sometimes requires arriving at a given waypoint at an assigned altitude. When this requirement is prescribed by a published arrival ... restriction. Even when ATC allows a descent at the pilot’s discretion, aircrews need to choose a waypoint and altitude for positioning convenient to start the approach. In either case, descending from a cruising altitude to a given waypoint…
