correct as is Heading symbol on the SA page missing

[franzy666]

Hi everyone,

 

I don't know if that's normal or if i miss something but the Heading symbol on the the HSI is visible for navigation but doesn't appear on the SA page.

So auto navigation is not easy when travelling long distances while displaying the SA page. However acting on the Heading Switch (HDG) when in AP HSEL has effect on the A/C heading...

Can you take a screenshot and show us what you mean?

 

thanks

I think he's referring to this symbol (apologies for the small size)

[franzy666]

yes that's what i refer to... this symbol doesn't appear on the SA page, its however functional since the aircraft will follow the actions on the heading switch if EP HSEL is selected

I am looking for the answer. 

 

The manual does not mention the Heading for the SA page although it does share similar functions. 

 

Situational Awareness (SA) Top Level The SA page is selected from pushbutton 13 (SA) on the TAC page. Upon selecting the SA page, the main SA page is displayed and, in many ways, duplicates the HSI page pushbutton options. Common HSI pushbutton elements include:
• MAP, pushbutton 6
• SCL, pushbutton 7
• MK2 (Mark) Point, pushbutton 9
• DCNTR (Decenter display), pushbutton 10
• WYPT/OAP/TGT, pushbutton 11
• Up Arrow (increment waypoint), pushbutton 12
• Down Arrow (decrement waypoint), pushbutton 13
• WPDSG (waypoint designate), pushbutton 14 DCS [F/A-18C]
• SEQ (1-3) (sequence), pushbutton 15
• AUTO, pushbutton 16
• MENU/TIME, pushbutton 18 All the above will function as they do on the HSI page, and changes on the HSI will translate to the SA page and vice versa.

Interior to the SA display also has much in common with the HSI display that includes:
• Compass Rose
• Lubber Line
• Waypoint/OAP/TGT Head and Tail
• TDC BRA to A/A Waypoint
• Ownship BRA to A/A Waypoint
• Aircraft Symbol
• TDC assignment symbol
• Air-to-Air Waypoint (bullseye)
• Selected Waypoint/OAP/TGT bearing, range, and time to (top right)
• Selected TACAN bearing, range, and time to (top left)

Lubber line = heading line, that should be there and it's not ingame, but the other guys seem to be referring to the heading select command marker which I don't think should appear in SA.

Hi,

Ill try to make me understand, but i might be wrong in the end if all this is normal.

 

Say you want to fly with the AutoPilot. You define your heading by pushing the Heading Set Switch (HDG) either side until you reach the desired heading, say 090. When pushing the Heading Set Switch, the Command Heading Marker (page 487 on the FA18 manual) will turn around the compas rose and mark 090 of the HSI. When you press AP, then HSEL on the UFC, the aircraft will turn to 090.

What I want to say is that when you are tactical, you use the SA Page rather than the HSI. So from the HSI, you press SA on the TAC page, you get basically all the contents of the HSI, plus tactical stuff like other aircraft etc... but the command Heading Marker is not present around the rose of the SA page. That makes navigation not easy using SA page.

 

But maybe this is normal... in that case i am sorry to bother you!
