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.
What is an aircraft equipment list?

furnished with the aircraft which specifies all the required equipment, and all equipment approved for installation in the aircraft
.
Who is required to have a minimum equipment list?

, based on the kind of operation or size and type of aircraft are required to have a Minimum Equipment List (MEL) in order to operate the aircraft with inoperative instruments or equipment. However, operators of the following types of aircraft may operate under part 91 without an MEL.
What is the minimum equipment list MEL and its purpose?
The Minimum Equipment List (MEL) is
a document and method aircraft operators use to obtain relief from Federal Aviation Regulations requiring that all equipment installed on the aircraft be operative at the time of flight
.
What is the difference between master minimum equipment list and minimum equipment list?
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 a kinds of operations 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.
What is the difference between Mel and CDL?
While the MEL describes the limitations of aircraft operation in case of a system being inoperative/having malfunctioned (e.g. transponder failure), the CDL deals with
situations where external parts of an aircraft are missing/fallen off
(e.g. fairings, aerodynamic seals or panels).
What minimum equipment is required for IFR flight?
In the United States, instruments required for IFR flight in addition to those that are required for VFR flight are:
heading indicator, sensitive altimeter adjustable for barometric pressure
, clock with a sweep-second pointer or digital equivalent, attitude indicator, radios and suitable avionics for the route to be …
What are the types of Mel?
There are
four different categories
; A – the deferral period defined in the comments column of the MEL, B – three days, C – 10 days, and D – 120 days. In closing, to operate an aircraft with inoperative instruments or equipment you have to comply with the requirements of 14 CFR Part 91.213.
How do I fly with Inop equipment?
Inoperative equipment and instruments must
be repaired, removed, replaced, or inspected and properly deferred again
at the next scheduled inspection (Ref 14 CFR Part 91.405(c)). An MEL created for use under Part 135 is a document created by the air carrier and approved by the FAA for that air carrier.
WHO Issues Minimum Equipment List?
The master minimum equipment list (MMEL) is a list established for a particular aircraft type by
the organisation responsible
for the type design with the approval of the State of Design which identifies items which individually may be unserviceable at the commencement of a flight.
Where do you find Minimum Equipment List?

in aircraft operating under Part 121, 125 and 135
.
Who prepares MMEL?
MMEL is defined on a per aircraft model basis. MEL is prepared by

Where is the kinds of equipment list?
If you fly one of the newer aircraft, you need to be familiar with the Kinds of Operations Equipment List, which is generally located in
the Operating Limitations Section of the POH/ AFM
. The KOEL is meant to be an easy-to-use reference for what the manufacturer deems essential for particular operations.
What is a kinds of operation list?
Kinds of Operations List (KOL). The KOL specifies the kinds of operations (e.g., visual flight rules (VFR),
instrument flight rules (IFR), day, or night
) in which the aircraft can be operated. The KOL also indicates the installed equipment that may affect any operating limitation.
Who develop the master minimum equipment list?
A minimum equipment list is developed by (or on behalf of) an aircraft operator based on a ‘Master Minimum Equipment List’ (Master MEL or MMEL) developed by
the aircraft manufacturer
. The MMEL is a document that covers all aircraft of a given type, or even a range of types.
