Approaches Flashcards
Alert Heights are normally uses for what type of approach?
Alert Heights are normally used for fail operational Category III approaches
Define Alert Height
Alert Height is a height above the runway, above which a Category III approach must be discontinued and a missed approach initiated if a specified failure occurs
What is “Fail Operational”?
Fail Operational refers to an AFDS capable of completing an ILS approach, autoland, and rollout following the failure of any single system after passing Alert Height.
What is “Fail Passive”?
Fail passive refers to an AFDS which in the event of a failure causes no significant deviation of airplane flight path or altitude. A DA(H) is used as approach minimums.
When are cold temperature corrections required?
Cold temperature corrections are required when at or below 0°c for all approaches that do not have RNP in the title except for RNAV with a published temperature range.
Are RNP approaches authorized if not within the charted limiting temperature value?
No, only RNAV (non RNP) approaches allow reversion to LNAV minima with cold temp corrections applied.
Is a temperature correction required to be added to a Decision Height?
No, just to Decision Altitudes.
Is a temperature correction required for a missed approach altitude?
Yes, including for RNP approaches.
How do we adjust corrected altitudes for the MCP?
Corrected altitudes shall be rounded up to the next higher 100ft increment for setting in the MCP
How are corrected altitudes entered on the LEGS page?
Enter altitudes corrected for temperature as “at or above” on the LEGS page by inserting the corrected altitude with an “A” after the altitude (eg. 3163A)
Are cold temperature corrections to the LEGS page required for ILS approaches?
No
Are cold temperature corrections required for an approach flown under visual conditions?
No, but may be done to correct the gradient path
What is the wind correction required if autothrottle is disconnected prior to touchdown?
Add 1/2 the steady headwind component plus all the gust speed. To a maximum of CREF + 20 knots. Maintain gust correction to touchdown, bleed off wind correction approaching touchdown
Gear down, Flaps 20 shall be extended no later than what point on approach?
Gear Down, Flap 20 no later than the FAF
What map scale is required no later than the FAF for the pilot flying?
Map scale set to 10
