Instruments (51-100)

During an approach to an autoland at 1500 feet:

• off line channels are manually engaged, flare mode is armed

• localizer is controlling the roll channel, off line channels are automatically engaged and flare mode is armed

• localizer is controlling the roll channel, stabilizer is trimmed nose up and roll out is armed

• provided both localizer and glide slope signals are valid LAND 3 will illuminate

What type of autoland system would be required for the landing to continue following a single failure below alert height?

• Fail-soft

• Fail-passive

• Fail-operational or fail-active

• Land 2 system

During an autoland the caption LAND 2 is illuminated. The system is:

• fail-active or fail-operational

• fail-passive

• approaching decision height

• requiring a crew input

During an autoland approach:

• flare is engaged at 1500'AGL

• localizer roll control is disengaged just prior to touchdown

• flare is disengaged prior to touchdown at 5' GA

• glide slope is the engaged pitch mode until 5' GA

In an autoland at 1000' AGL with two autopilots engaged:

• the armed roll mode would be LOCALIZER

• the engaged roll mode would be GLIDE SLOPE

• the engaged pitch mode would be FLARE

• the engaged roll mode would be LOCALIZER

If a fault develops in a triplex autopilot system during an approach, the system will revert to:

• fail-passive and the landing may continue

• fail control wheel mode

• fail-operational

• a manual disconnect

Central Air Data Computers (CADCs) transmit data concerning;-

• airspeed, altitude and decision height

• airspeed, altitude and Mach number

• airspeed, attitude and Mach number

• airspeed and altitude only

The autothrottle is used to control some factors during the three primary control modes; they are:

• EPR, Mach and Speed

• EPR, wheel and speed

• EPR, Mach and altitude

• EPR, wheel and altitude

During a CAT 2 ILS automatic approach, the source for altitude information is the:

• basic altitude capsule stack

• x

• radio altimeter which becomes effective below about 2500 feet

• mode comparator sensor

The type of automatic landing system which would necessitate a manual landing after a system failure during an automatic approach is:

• fail-passive

• fail-safe

• fail-active

• fail-operational
