Large Model Endorsement (LM)

The LM test can be performed with any large fixed wing, helicopter or multirotor unmanned aircraft that qualifies for Certification as a Cat 1, 2 or 3 aircraft as described in the Large Model Code of Practice.

It is a MFNZ requirement that anyone flying a model in these categories must hold the Large Model endorsement.


The Endorsements are BP (LM), GD (LM), HP (LM), BT (LM), and MR (LM).



The Large Model Endorsement rating comprises the following two (2) test components:

1/ Oral Questions
2/ Test Flight

These two tests must be carried out with a MFNZ registered club appointed examiner or a combination Inspector/Examiner detailed in Item 2, below, Test Flight.

2.0 TEST FLIGHT
Pilots must perform the LM endorsement using a schedule of maneouvres decided by the pilot and approved by the Inspector IAW Section 6.8 of the Large Model Code of Practise. The manoeuvres approved by the Inspector should be listed in the comments box on Form C.
Note:
A pilot wishing to undertake their LM endorsement with a Cat 1, 2 or 3 registered aircraft that is undergoing its’ five (5) certification test flights may do so provided:
(a) Both the inspector/witness AND examiner are present during the flights. Any one of the 5 test flights may be called as the LM endorsement check flight so long as the examiner is advised before the flight commences. This allows the pilot to become familiar with the aircraft before the endorsement check flight.
(b) The examiner must confirm that the test manoeuvres flown for the endorsement check flight are those approved by the Inspector on Form C.
A list of suggested manoeuvres to assist pilots that choose LMCOP Section 6.8 can be found here: LM maneouvre Library.
This list is by no means comprehensive and is to be used as a guide only. The pilot may choose whichever manoeuvres suit their style and aircraft. It should be considered that those chosen during the testing phase are also the only manoeuvres permitted to be flown once the Permit to Fly is issued.
Important Note.
Existing owners of Cat 1, 2 or 3 models will be granted the LM endorsement as a “grand-parented right” on the Large Model types they have completed certification flights on and hold a permit to fly as of 30 November 2017.
