Alternate Rules Flashcards
What is a requirement for a takeoff alternate regarding flying time?
The alternate airport must be within one hour’s flying time at normal cruising speed, in still air, all engines operating.
What is the second requirement for a takeoff alternate?
The alternate airport weather needs to be above the ‘Alternate Airport IFR Weather Minimums’ table in Ops Spec C055.
Where can a takeoff alternate be listed in a Flight Plan?
In block 18, Other Information.
How should a takeoff alternate be indicated in a Flight Plan?
Add the indicator ‘TALT/’ followed by the ICAO airport code.
Fill in the blank: A takeoff alternate must be within _______ of the departure airport.
one hour’s flying time
True or False: A takeoff alternate can be any airport regardless of weather conditions.
False
Provide an example of how to indicate Teterboro as a takeoff alternate.
TALT/KTEB
When is a landing alternate required to be selected?
A landing alternate is required if the ceiling is forecast to be less than 2,600 feet.
What is the minimum ceiling requirement for an airport with a circling instrument approach authorized?
The ceiling will be at least 1,500 feet above the lowest circling approach MDA.
What is the minimum ceiling requirement if a circling instrument approach is not authorized?
The ceiling will be at least 1,500 feet above the lowest published minimum or 2,000 feet above the airport elevation, whichever is higher.
How do you calculate the required ceiling when circling is not authorized?
Take the lowest applicable published minimums and add 1,500 feet.
What must you do when flying internationally regarding filing an alternate?
You must comply with the rules of the particular country you are operating in.
True or False: Many countries require that you file an alternate regardless of the weather.
True.
What must you determine to meet textual requirements published in the ‘For Filing as Alternate’ section?
If you can meet any textual requirements
This involves checking specific criteria for alternate airport usage.
What constitutes a different NAVAID?
A different frequency and/or ID
For example, ILS 13 and 31 with the same frequency and identifier are not different NAVAIDs.
What must you do if there is only one NAVAID?
Add 400 to the ceiling and one mile to the visibility to the lowest straight in or circling approach minimums.
NAVAID stands for Navigational Aid, which assists in navigation and approach procedures.
How is a ‘different runway’ commonly interpreted?
A different runway is commonly interpreted as one with a different number, even if it is the same piece of pavement.
For example, runway 13 and runway 31 would be considered different runways.
What does ‘suitable’ mean in the context of runway selection?
Suitable refers to whether you can land there with your airplane considering winds and landing distance requirements.
This ensures safety and compliance with operational limits.
What is the preferred approach selection method when choosing two approaches?
Preferably, choose the two approaches with different navaids and the lowest minimums.
This maximizes the chances of a successful landing under minimum conditions.
What does the acronym TEMPO represent in a forecast?
Conditions expected to last for less than an hour at a time and expected to occur during less than half of the valid time period
TEMPO is crucial for determining alternate airports.
When is a TEMPO forecast considered for determining alternate airports?
If it is during the time period one hour before to one hour after your ETA
The forecast ceiling or visibility is controlling in this case.
What does the acronym PROB indicate in a forecast?
The probability or chance of thunderstorms or other precipitation is between 30 and 50%
PROB is significant for alternate airport decision-making.
When is a PROB forecast considered for determining alternate airports?
If it is during the time period one hour before to one hour after your ETA
The forecast ceiling or visibility is controlling in this context.
What does ATA Code stand for?
Air Transport Association Codes are a numbering system for aircraft systems consistent throughout the aviation industry
What is the purpose of the CDL?
The CDL is a listing of FAA-approved non-structural external parts that may be missing but the airplane remains airworthy
What does MEL stand for?
Minimum Equipment List
Who creates the MEL?
Commercial operators (FAR 135, 121 etc.) based upon the MMEL
What is the MMEL?
Master Minimum Equipment List created by the FAA and the manufacturer
What does NEF stand for?
Non-Essential Equipment And Furnishings
What are O and M items?
Operation and Maintenance items that may be inoperative but must have associated Operations or Maintenance procedures accomplished
True or False: The MMEL lists items that may be inoperative without compromising safety of flight.
True
What must FAR part 91 operators develop alongside the MMEL?
A Procedures Manual
What chapter in maintenance manuals corresponds to ATA code 21?
Air Conditioning
