A minimum equipment list (MEL) is a list which provides for the operation of aircraft, subject to specified conditions, with particular equipment inoperative (which is) prepared by an operator in conformity with, or more restrictive than, the MMEL established for the aircraft type.
Do all aircraft have a Minimum Equipment List
14 CFR Part 91.213 (d)(1) states that an aircraft does not require an approved Minimum Equipment List provided the aircraft is a non-turbine powered airplane for which a Master Minimum Equipment List has been developed.
What is difference between Mel and MMEL
Their difference is that the MEL is formulated for a particular operator and a certain aircraft or a few aircraft, whereas the MMEL is formulated for all aircrafts of this type. The MEL of the operator shall be based on the MMEL of a specific aircraft type and model approved by the authorities.
What is mel and cdl
MEL (Minimum Equipment List) or CDL (Configuration Deviation List) refers to the situation where an aircraft has certain components on the airplane that are inoperative (e.g., MEL may be broken air-conditioning) or missing (e.g., CDL may be missing winglet).
What are the 4 parts of an mel
A FAR Part 91 MEL consists of the MMEL for a particular type aircraft, the MMEL’s preamble, the procedures document, and a LOA. The FAA considers the MEL as an SC. As such, the MEL permits operation of the aircraft under specified conditions with certain equipment inoperative.
Where is Mel found aviation
You will mostly find MELs in aircraft operating under and 135.
Do all aircraft have an MMEL
Aircraft Type or Size: 14 CFR Part 91.213 (d)(1)
However, even if an MMEL has been developed for a small rotorcraft, small aircraft, glider, or lighter-than-air aircraft, its use is optional.
What is an MMEL in aviation
MMEL Explained
Master Minimum Equipment List (MMEL): A master list of items on an aircraft that are allowed to be inoperative under specific conditions without impacting the safety of flight. The MMEL is established by the aircraft manufacturer and approved by the national aviation authority.
Who develops the MMEL?
The MMEL is an Airbus document, developed by the Flight Operations Support and Services Department. Operators use the Airbus MMEL as a reference for creating their own MEL, which is provided to their flight crews, line maintenance personnel, and/or flight operations personnel.
Who creates an Mel
6 An MEL is developed by the operator for their particular operation (parts 91K, 121, 125, and/or 135). An MEL is typically developed from a Master Minimum Equipment List (MMEL) for the aircraft type.
Do I need an LOA to use a MMEL
Many U.S. Part 91 operators request FAA authorization to use a master minimum equipment list (MMEL) to legally fly with certain inoperative equipment. This authorization is provided through a Letter of Authorization (LOA) and issuance of D095.
How does an mel work
MEL or Minimum Equipment List is an exact list of equipment, instrument, and procedures that allow flying an aircraft under specific conditions and limitations. In a few words, it is a document that enables a pilot to legally operate an aircraft, even if something is not working.
What is CDL in aviation
A configuration deviation list (CDL) is a list, established by the organization responsible for the type design with the approval of the State of Design, which identifies any external parts of an aircraft type which may be missing at the commencement of a flight, and which contains, where necessary, any information on
What is AML in aviation
AML means Aircraft Maintenance Licence and is normally called a Part-66. This official document is issued by the aviation authorities of an EU member state.
What is Nef aviation
Nonessential equipment and furnishings are those items installed on the aircraft as part of the original certification, supplemental type certificate, or engineering order that have no effect on the safe operation of flight and would not be required by the applicable certification rules or operational rules.
What are O and M items in Mel
Where the (O) or (M) symbols appear, an operating or maintenance procedure must be developed which provides clear direction to the crew members and maintenance personnel of the action to be taken. This procedure must be included in the MEL.
What is a mel used for?
The MEL is a commonly used tool allowing for the safe and continuous operation of the aircraft until rectification of certain inoperative equipment or unavailable system functions that are not adversely affecting the airworthiness of the aircraft.
What is the SRM in aviation
Single-pilot resource management (SRM) is the art of managing all onboard and outside resources available to a pilot before and during a flight to help ensure a safe and successful outcome. Incorporating SRM into GA pilot training is an important step forward in aviation safety.
What is AMM in aviation?
Aircraft Maintenance Manual (AMM) | SKYbrary Aviation Safety.
What is a kinds of equipment list
As the name implies, the Kinds of Operations Equipment List (KOEL) is a list of equipment installed in an aircraft that specifies for which kinds of operations a specific piece of equipment is required. The KOEL is used as part of the process of determining if an aircraft with inoperative equipment is airworthy.
Is TCAS Mel?
TCAS, like any other on-board equipment, is covered in a Minimum Equipment List (MEL) which allows the operation of aircraft with particular equipment temporarily inoperative, subject to specified conditions (more information about MEL on SKYbrary).
What is the minimum required equipment for VFR day flight
For VFR flight during the day, the following instruments and equipment are required: (1) Airspeed indicator. (2) Altimeter. (3) Magnetic direction indicator.
Can Mel be extended
If the operator wants or needs to extend the interval again, the operator must get approval from the FAA office. A certificate holder/program manager is not authorized to extend the maximum repair time for category A and D items, as specified in the approved MEL.
What are the 5 T’s in aviation?
The five T’s: TURN, TIME, TWIST, THROTTLE and TALK. I use them as a mechanism for thinking in front of the airplane, as a way to think deeply about the next event.
Can a plane land without ATC
The most common reasons for landing without clearance are: Loss of Communication – e.g. due to equipment failure or mistuning the next (TWR) frequency. In some cases, e.g. VFR flights, the tower controller might not even be aware that an aircraft is approaching and is intending to land.
Can a plane fly without an APU
Aircraft are allowed in general to fly without an APU. Exceptions are flights with two-engined aircraft and long routes over water or terrain without an alternate airport – so called ETOPS flights. ETOPS stands for Extended Twin Operations.
What is the 3/6 rule in aviation
For larger aircraft, typically people use some form of the 3/6 Rule: 3 times the altitude (in thousands of feet) you have to lose is the distance back to start the descent; 6 times your groundspeed is your descent rate.
What is MFD in cockpit
Multi-Function Display (MFD) is an avionic device that manages and displays information such as the aircraft’s flight, navigation, engine, hull and alarm on a single AMLCD Ruggedize display screen with pilot-friendly graphics. Display systems & instruments. Avionics.
What is AMC in aircraft
AMC-20: General AMC for Airworthiness of Products, Parts, and Appliances.
What is the maximum number of days for which Mel can be scheduled
3 In all other cases, when an MMEL revision is issued, operators will be allowed 90 days from the date of notification to amend their MEL.
Who built MCAS
The Maneuvering Characteristics Augmentation System (MCAS) is a flight stabilizing feature developed by Boeing that became notorious for its role in two fatal accidents of the 737 MAX, which killed all 346 passengers and crew among both flights.
Why is Mel important in aviation
An MEL essentially is designed to enable safe operation of aircraft, subject to specified conditions, when certain equipment is inoperative. As such, the MEL has a vital function as one barrier in the layers of defenses against an unacceptable risk level.
Does the Mel apply to revenue flights
The MEL is defined as a dispatch document and therefore the MEL is not applicable in flight. However, if a system or equipment defect is detected during flight, the MEL information may be useful to assess the likely dispatch condition for the next flight.
