The primary purpose of a supercritical wing section is to:
Increase the critical drag rise number
When considering pilot related operating techniques to get the greatest braking effort from an anti-skid system, the pilot should:
Maintain constant brake pedal pressure, and let the anti-skid do the work
The total loss of system ‘A’ and system ‘B’ hydraulic systems in a 767-300 ER aircraft including their respective electrically driven pumps, means that hydraulic power is limited to supplying:
The primary flight controls, leading and trailing edge flaps
You are programming the FMC for the departure, and the CDU screen shows an annunciation of “NO DATA” when a particular waypoint is entered. Which of the answers below best describes the method(s) by which the waypoint can be manually entered?
Latitude/Longitude
The purpose of the “swirl vanes” is to:
Reduce the axial air velocity, and anchor the flame in the primary zone
T/F: ‘Annular’ combustion chamber types, when compared with “can annular” types have the advantage of being more space efficient, suffer less pressure loss, and can be shorter in length:
True
The turbine ‘shroud ring’:
Reduces blade vibration by stiffening the blade tip
Which statement is most correct about turbine blade creep stress values with time in service?
Initially during the “primary” stage, and finally in the “tertiary” stage blade stretching is significant, being less between these stages
Which statement is most correct regarding Avtur?
It weighs more per unit volume than Avgas
Which statement is most correct regarding fuel quantity readings taken using drip-sticks and/or magna-sticks?
Readings need to be corrected for wing low, and tail high/low conditions
Which answer best represents the display characteristics of the ‘Expanded ILS mode’?
Weather radar returns can be displayed, orientation is heading up. Aircraft is displayed as a white triangle at the bottom of the display. Compass arc shown is 70 degrees
Provisional or modified routes are displayed as:
A dashed white line
The aircraft is cruising at FL310 in VNAV with the auto-throttle and autopilot engaged approaching the FMC predicted Top of Descent point. The MCP altitude window value is 35,000 ft. What will happen as the aircraft reaches Top of Descent?
The aircraft will continue to cruise at FL310 and VNAV will disengage
Which statement is most correct regarding lubricating oil types?
Synthetic oils are less likely to produce carbon deposits
Large transport jet aircraft use:
Air starters
