FEAST Logical Reasoning and Rules 2

Question 1

Rule: Aircraft may only enter sector Alpha if: (1) altitude is between FL200 and FL400, and (2) the aircraft is on an approved route.
Aircraft X is at FL250 on an approved route.
Aircraft Y is at FL180 on an approved route.
Aircraft Z is at FL300 on a non-approved route.
Which aircraft may enter sector Alpha?

Accepted Answer

Aircraft X only

Answer

Aircraft X and Y

Answer

Aircraft X and Z

Answer

Aircraft Y and Z

Question 2

A procedure states: 'Separation minima are reduced from 5 NM to 3 NM only if: (a) radar coverage is confirmed, and (b) the sector is not in a high-density period, and (c) a supervisor approves the reduction.' A controller wants to apply 3 NM separation. The radar is confirmed, the supervisor has approved, but it is a high-density period. The controller may:

Accepted Answer

Not apply 3 NM separation — all three conditions must be met and condition (b) is not satisfied

Answer

Apply 3 NM separation — two out of three conditions are met

Answer

Apply 3 NM separation — the supervisor's approval overrides the density condition

Answer

Apply 3 NM separation only if the supervisor explicitly overrides condition (b)

Question 3

Sequence rule: Aircraft must be sequenced for the ILS as follows: Heavy aircraft first, then Medium aircraft, then Light aircraft. Within each weight category, earlier estimated arrival time (EAT) takes priority. Four aircraft have these profiles: Alpha — Medium, EAT 12:10; Bravo — Heavy, EAT 12:15; Charlie — Light, EAT 12:05; Delta — Heavy, EAT 12:08. The correct ILS sequence is:

Accepted Answer

Delta, Bravo, Alpha, Charlie

Answer

Charlie, Delta, Bravo, Alpha

Answer

Bravo, Delta, Alpha, Charlie

Answer

Alpha, Delta, Bravo, Charlie

Question 4

Rule: A squawk code of 7700 indicates general emergency. A squawk code of 7600 indicates communication failure. A squawk code of 7500 indicates hijack. A radar target appears with squawk 7600. The controller's correct interpretation is:

Accepted Answer

The aircraft has lost radio communication and cannot be contacted on the normal frequency

Answer

The aircraft has declared a general emergency

Answer

The aircraft has been hijacked

Answer

The aircraft's transponder is malfunctioning

Question 5

An instruction states: 'Vectors to final shall not be issued if the glide slope is not captured, unless an ILS hold short instruction is applied.' An aircraft on base leg has not yet captured the glide slope. A hold short instruction has been applied. Can vectors to final be issued?

Accepted Answer

Yes — the exception condition (hold short instruction applied) is satisfied, so vectors to final may be issued

Answer

No — vectors to final require glide slope capture regardless of other conditions

Answer

No — the hold short instruction cancels all normal vectoring procedures

Answer

Yes — glide slope capture is not relevant during base leg

Question 6

Five aircraft are holding at the same fix at different levels: FL90 lowest, FL100, FL110, FL120, FL130 highest. Inbound aircraft must be descended from highest to lowest and released for approach in that order. A slot opens for an approach. Which aircraft is released first and which second?

Accepted Answer

FL130 released first, FL120 released second — descend from highest hold to lowest in sequence

Answer

FL90 released first as it is already at the lowest level and closest to the runway

Answer

FL130 released first, then all others simultaneously

Answer

The aircraft with the longest holding time is released first regardless of level
