With regard to the speed stability characteristics of a jet transport aircraft when operating in the region of reverse command -

any decrease in speed will result in increased power required to maintain altitude while an increase in speed will result in less power required to maintain altitude

When flying a jet transport aircraft on approach with steep wind gradients or wind shear and/or gusts the approach speed should be modified accordingly. As a rule of thumb the approach speed may be increased to a max value of VREF+15kts for wind gradients by adding half the wind speed to the normal approach speed. In gusty conditions the approach speed may be increased to a max of VREF+10 by adding half the wind speed and half the gust value. If the reported wind speed was 20kt gusting to 30kt to the appropriate approach speed would be?

VREF+15

The measurement of temperature in a gas turbine engine is one of the most critical items of information the pilot needs for safe operation.

prevent flameout

if thermocouples are used in parallel to measure the temperature in a jet engine, the temperature shown will be ?

the average temperature of all probes on the circuit

when conducting a CAT IIIc autoland in an aircraft equipped with 3 autopilots, and you see “Land 2” indicated on the autoland status announciator, the status of the autoland system would be -

Fail Passive, and any failure of any single item would result in no significant deviation from flight path

Some jet transport aircraft are equipped with a feature known as aileron lockout. If aileron lockout appears as a caution message on the EICAS you would expect to experience?

If the EPR probe at the compressor inlet of a jet engine becomes blocked with ice during taxiing and the pilot advances the thrust levers for take off to the predetermined EPR setting for take off , the likely result is ?

the EPR gauge will overread and the engine thrust will be less than take off thrust

Regarding the cabin altitudes at which cabin altitude warnings occur and the cabin altitude at which emergency passenger oxygen masks deploy in the event of a depressurisation in most jet aircraft is?

cabin altitude warning at 10,000ft and oxygen mask deployment at 14,000ft

if the FMC detects a difference between the FMC computer fuel quantity and the fuel gauge indicated quantity it will ?

alert the pilot(s) to the discrepancy with a fuel quantity error message and the pilot then decides which quantity to use for subsequent navigational calculations

Advantages of a tricycle undercarriage configuration include ?

greater braking effectiveness, better visibility during landing and taxiing? the CG is forward of the main gear which minimises ground loop tendencies
