PMDG 777 false terrain alarm

Recommended Posts

I was landing at LHR with the 777-300ER the other day, and when I was locked and coming down the glideslope, at about 1000ft, the terrain alarm screamed all the way until I touched down on 27R, despite I was in full landing configuration (flaps 30, gear down, autobrakes 1)

scenery : UK2000 London extreme

 

I would be grateful for a reply.

Well it did happen to me and I am just desperate to find a solution to fix a little flaw in an otherwise perfect aircraft.

P.S. Did you use the PMDG 777?

Same here, same aircraft, same Rwy. There are no hills on that glideslope to trigger terrain alarms.

Can you elaborate on 'landing config for a T7'?

oh I apologize

 

No worries. Thanks for making the correction.

 

 

 


I would like to ask what is the landing config for a T7?

 

You should be at either Flaps 25 or 30. Flaps 20 is only used in non-normal situations (engine out), and the crew would use the GPWS FLAP OVERRIDE switch to tell the plane that this action (landing with Flap 20) is intentional. The switch is located above the gear handle and labeled FLAP OVRD.

yes but I am landing in full landing configuration as mentioned above

 

It is also happening at every airport

I think the plane is not recognizing the aircraft is in landing config

Full names. Every post.

 

Have you set a route in the FMC? Origin and destination?

it kept warning terrain terrain pull up

NOT too low terrain

and NEVER too low gear

OR too low flaps

yes I did programme the FMC correctly, including the VREF
