Manual UFC for RALT or BALT

[Toni Carrera]

Hi Fellow Pilots,

 

Is it possible, by way of the UFC, to enter a desired height for the aircraft on either BALT or RALT?

 

Thanks in advance

According to NATOPS, this is not possible. Warning, unformatted C&P, may be hard to read

 

2.9.2.3 Barometric Altitude Hold. To establish barometric altitude hold, press the button next to

the option display window displaying BALT. The existing barometric altitude at time of engagement

is captured and maintained. Heading or attitude hold is maintained, depending upon which mode was

previously engaged. The operating range is 0 to 70,000 feet. ATTH, CPL (MC OFP 13C AND UP), or

HSEL can be selected with BALT to provide lateral control. CSS causes reversion to heading or

attitude hold, depending upon which was previously engaged.

 

2.9.2.5 RADAR Altitude Hold. To establish radar altitude hold, press the pushbutton next to the

option display window displaying RALT. Engagement is indicated by a colon appearing in the window

next to RALT. The existing radar altitude is maintained upon engagement. Radar altitude hold

coverage is from 0 to 5,000 feet. If no other mode is selected, the lateral axis control remains in heading

hold. In this configuration, either CSS or the roll trim switch can be utilized with automatic turn

coordination up to 45° with altitude maintained. ATTH, CPL (MC OFP 13C AND UP) or HSEL can

be selected with RALT to provide lateral control.
