V speeds not available

Recommended Posts

I flew from Mexico City to Miami,Florida without any problems.

 

After that I tried a flight from Bogota ( Columbia ) to Miami with the same payload,fuel quantity as before.

 

When selecting the v speeds I got a CDU message : V speeds not available.

 

I wonder what the problem is ? Altitude ?  However the altitude difference between Mexico City and Bogota is only a few hundred

meteres .

 

Any ideal wat is wrong ?

 

Thanks

Any ideal wat is wrong ?

See FCOMv2 page 11.60.19. I receive this message when there is a mismatch between GTW, runway length, altimeter setting, flaps, derates, and assumed temperature.

Few hundred meters however puts Bogota comfortably over 8000ft. Which might mean there is no more V speeds in database.
