A320 MEL
 

Hello Fellow Aviators,

I am a newbie to A320. I want to know more about the application of MEL on A320. Suppose in flight I get ECAM >

NAV ADS-B RPTG 1 FAULT

NAV ADS-B RPTG 2 FAULT



essentially both ADS-B Reporting systems have failed.

Then I applied OEBs - None // Tech Notices - None // ECAM - No Actions listed // QRH - Nothing in Abnormal PROC // Comp Reset - No System Reset Related to ADS-B OUT //

FCOM Procedure says ATC/XPDR…SYS 2(1) however this is only for a Single system failure.



Now I go to MEL 34-50-10 ADS-B OUT Function

34-50-10A Not required for the intended route

34-50-10B Required for the intended route

In this, I apply 34-50-10 B which specifies that for airspace I am flying in it requires ADS-B Out functionality if I am flying RVSM.

So do I need to Vacate RVSM?

My understanding is MEL is applicable only ON GROUND from Door Closure till application of take-off Power. Then why would I refer and apply MEL in the air?

Yes, MEL need not apply when airborne, but it can be useful to refer to for the notes, and possible operational procedures and consequences.

I would just inform ATC and follow their instructions. As long as you can maintain RVSM, and TCAS remains operational, I can't see a problem with continuing that flight?

Just trot on further north-west until you leave the area of GPS-spoofing, problem solved.
