B763 High Altitude

………. Act as a membrane between the air and the blood through which gases can diffuse. Alveoli. Plasma cells. Hemoglobin cells. The lungs.

Mountain waves can be detected by the presence of: Stratiform clouds. Towering cumulus. Lenticular clouds. Virga.

These 2 features found in most transport aircraft wings make them very susceptible to Dutch Roll: Wing mounted engines and winglets. Wing leading edge devices and dihedral. Wing sweep and Fowler flaps. Wing dihedral and sweep.

………….. prevent ambient pressure from exceeding cabin pressure. Negative pressure relief valves. Outflow valves. Bleed valves. Safety relief valves.

……………. Causes moving air masses to appear to deflect to the right in the northern hemisphere and appear to deflect to the left in the southern hemisphere. Rotational inertia. Centrifugal force. Coriolis effect. Gravitational force.

With reference to wake turbulence for a typical jet transport aircraft, the wake descends behind the aircraft at approximately: 300 - 500 fpm. 500 - 900 fpm. 1000 - 1500 fpm. 1500 - 2000 fpm.

If a pressurization problem occurs or is suspected, crew members should: Immediately try to troubleshoot the problem using checklist and aircraft manuals. Immediately contact company maintenance personnel for assistance. Immediately don oxygen masks and establish communications prior to any attempt at troubleshooting. Attempt to contact cabin crew for an assesment of conditions in the cabin.

…………. Occurs when dissolved gases come out of solution in body tissues due to a drop in ambient pressure. Barotrauma. Hypoxia. Loss of consciousness. DCS.

Thrust Specific Fuel Consumptions (TSFC) is. Lowest at jet engine RPM approaching idle. Lowest at jet engine RPM approaching 100%. Highest at jet engine RPM approaching 100%. Constant across all RPM ranges.

Flight crew oxygen masks are normally: Continuous flow type. Oxygen generator type. Diluter demand type. Positive pressure type.

If completing an emergency descent in oceanic airspace. In compliance with established contingency procedures, turn from the assigned route or track. Broadcast intentions on 121.5MHZ set transponder code to 7700 and select emergency mode on the ADS/CPDLC system if applicable. Turn on exterior lights and watch for conflicting traffic both visually and with reference to TCAS displays. all the options.

The bleed air supply is normally cooled, conditioned and supplied to the cabin for pressurization by an Air Cycle Machine, commonly referred to as : Air conditioning pack. Ram air turbine. Bleed air turbine. Bleed air pack.

Maximum range speed is flown at: Lowest cruise speed. ECON speed. L/D max. Lowest fuel flow.

Clear Air Turbulence (CAT) is normally found: At the tropopause above the jet core and at the frontal slope below the jet core. In the vicinity of an upper through, where there is a sharp bend in the jet stream. At the confluence of 2 jet streams or the lee side of high terrain. all the questions.

Passenger safety is dependent on an expeditious descent to a safe altitude, normally …………….., where the effects of altitude on the average person are negligible. FL180. 10.000 ft Above ground level. 10.000 ft Above sea level. 14.000 ft Above sea level.

Pressure lapse rate: Is constant from sea level to the edge of space. Is greater at sea level and decreases with altitude. Is smallest at sea level and increases with altitude. Decreases with altitude up to the tropopause, then remains constant.

When cosmic radiation levels are elevated, overall exposure can be minimized by flight planning …………. more northerly routes at lower flight levels. more southerly routes at lower flight levels. More northerly routes at higher flight levels. more southerly routes at higher flight levels.

The standard lapse rate is ….. C per thousand feet. 0.98. 1.98. 2.98. 3.98.

…………………….. is the lowest of the maximum certified altitude, the thrust limited altitude and the buffet or maneuver limited altitude. Optimum cruise altitude. Recommended cruise altitude. Alternate cruise altitude. Maximum cruise altitude.

In areas of high terrain, an emergency descent should be initiated to Minimum Safe Altitude (MSA) only, and: Turn to heading that will have the aircraft exit the area of high terrain in he shortest time possible. Increase to maximum cruise speed to exit the area of high terrain in the shortest time possible. Continue descent below Minimum Safe Altitude (MSA) if the aircraft is equipped with EGPWS map displays. Attempt a “cloud break procedure” then descend further with visual reference to the ground.
