ADX ADX Airport Operations and Ground Procedures 2

Question 1

What does the term 'alternate airport' mean in the context of US domestic dispatch?

Accepted Answer

An airport listed in the dispatch release where the flight may land if the destination becomes unusable

Answer

An alternate airport is filed in the dispatch release as a contingency landing site if the destination airport cannot be used due to weather or other conditions.

Question 2

What is an Airport Surveillance Radar (ASR) approach and when would a dispatcher consider it?

Accepted Answer

A radar-vectored instrument approach used when ILS or other precision approaches are unavailable

Answer

An ASR approach uses ground radar to vector the aircraft to the runway, providing a non-precision approach option when precision approaches are out of service.

Question 3

Under FAR Part 121, what is the minimum fuel requirement a dispatcher must ensure is aboard a domestic flight?

Accepted Answer

Enough fuel to reach the destination, fly to the alternate, and have 45 minutes of reserve at cruise speed

Answer

FAR 121.639 requires domestic Part 121 flights to carry enough fuel for the destination, the alternate, plus 45 minutes at normal cruise consumption.

Question 4

What is a 'sterile cockpit' rule and how does it affect dispatcher communications?

Accepted Answer

Below 10,000 feet, crew must focus on flight duties; dispatchers should avoid non-essential calls during this phase

Answer

The FAA sterile cockpit rule prohibits non-essential communications and activities below 10,000 feet, so dispatchers must time critical messages to avoid critical flight phases.

Question 5

What is the significance of 'TDZ elevation' (Touchdown Zone Elevation) for a dispatcher planning an instrument approach?

Accepted Answer

It is the elevation used as the reference for decision altitudes on instrument approaches, affecting weather minimums

Answer

TDZ elevation is the highest elevation in the first 3,000 feet of the runway landing surface and is used as the reference point for calculating instrument approach minimums.
