IFOD Flashcards
mel/cdl ops specs performance weight and balance
What does the MEL stand for?
Minimum equipment list
What is the MEL used for?
The MEL lists inoperative aircraft systems. It is used to determine whether or not a flight is legal to depart with a particular component inoperative. The MEL provides this information to the pilots and flight dispatcher. The MEL is referred to only on the ground, not while in flight.
What CDL stand for?
Configuration Deviation List
What is the CDL used for?
The CDL lists components on the outside of the aircraft that are physically missing from the aircraft. When a part is removed, the configuration of the aircraft is changed. Sometimes there are takeoff and landing weight penalties associated with CDL items.
If an item is inoperative, and it cannot be found in the MEL, what course of action should be taken?
If the item cannot be found in the MEL, then the item must be fixed.
If an airplane is already out of the gate, sitting at the end of the runway, and the captain calls on the radio to advise that an electrical generator just went inoperative, what must be checked to see if the flight is still legal to depart?
The MEL
Is the MEL used on the ground, in-flight, or both?
The MEL is referred to only on the ground . For issues in flight refer to the operating manual, and the emergency checklist.
What does the AFM stand for?
Airplane Flight Manual
What is Ops Specs?
Operation Specification
What is the difference between the AFM and the ops specs?
The AFM is a manual for the aircraft written by the manufacturers. The Operation Specification is a company written manual that provides information about the company’s geographic and operating preferences.
What is an adequate airport?
An airport is considered adequate when it satisfies the aircraft performance requirements applicable at the expected landing weight, availability of the airport, over flight and landing authorizations, capability of ground operations assistance, and availability of NAVAIDs, and airport category for rescue and firefighting.
What is a suitable airport?
A suitable airport is an airport confirmed to be adequate, but also has the dispatch weather requirements in term of ceiling and visibility. In addition, crosswind forecast should be acceptable for the same period.
What is the maximum structural takeoff weight for the B737?
174,200
Is it possible to always takeoff at 174,200 lbs?
No
What are some of the factors that may have an effect on the maximum allowable takeoff weight?
hint: RAFTCAME
Runway length and slope Airport Elevation Flap setting Temperature Contaminated runway (snow,slush,ice, etc) Air conditioning packs off MEL/CDL items Engine anti ice on wind/ weather
What document does one refer to when considering maximum allowable takeoff weight for each flight?
The airport runway analysis will determine the maximum allowable takeoff weight for each flight
What is the standard flap setting for takeoff with the B737?
15 degrees of flap
What other flap setting are available for takeoff with the B737?
5 and 25 degrees of flap
What effect does snow, ice, or slush on a runway have on takeoff performance?
Decreases performance. Contaminated runways call for large takeoff weight penalties.
Are air conditioning packs normally on or off for takeoff?
Normally on, however, they can be turned off in order to achieve a higher maximum allowable take off weight.
If the air temperature increases, what effect does it have on takeoff weight?
The higher the temperature, the more of a penalty there is to the maximum takeoff weight.
Define the center of gravity?
The point at which all of the weight of an object is considered to be concentrated (the point at which the airplane would balance perfectly on the head of a pin.)
What does the MAC stand for and what is it?
Mac stands for Mean Aerodynamic Chord. It is the chord of an imaginary rectangular wing that has the same aerodynamic characteristics as the actual wing.
What is the STAB trim setting for?
The STAB trim is used to adjust the stabilizer for the correct airplane nose up setting for take off.
