Abstract
A method, apparatus and computer program product for assisting the pilot of an aircraft in making a go-around decision. Various aircraft parameters are monitored during the approach to land and a risk level assessed. When the risk level exceeds a specified threshold, an alert is provided.
Claims12
A method for alerting the pilot of an aircraft to a potential go-around condition comprising the steps of:
- monitoring a plurality of parameters indicative of an unstabilized approach;
- assigning a risk of go-around value to each of said parameters;
- summing the assigned risk values;
- and
- asserting an alert signal when said summation exceeds a predetermined threshold amount, asserting further comprises:
- asserting a go-around caution alert signal when said value exceeds a first threshold amount and is less than a second threshold amount;
- and
- asserting a go-around warning signal when said value exceeds said second threshold amount.

A method of alerting the pilot of an aircraft to a potential go-around condition comprising the steps of:
- monitoring a plurality of parameters indicative of a runway landing length required;
- assigning a risk of runway overrun value for each of said plurality of parameters;
- summing the assigned risk values;
- and
- asserting an alert signal when said summation exceeds a predetermined threshold value,
- wherein the plurality of parameters include runway length,
- wherein said step of asserting an alert signal further comprises the steps of:
- asserting a go-around caution alert signal when said value exceeds a first threshold amount and is less than a second threshold amount;
- and
- asserting a go-around warning signal when said value exceeds said second threshold amount.
