Hey everyone,. .I have made an award winning freeware heads up guidance system for Microsoft Flight Simulator 2000 and 2002 (for all you jealous FO's out there) based on the one Southwest Airlines Uses. . .For any one that uses the Flight Dynamics Heads Up Guidance system in the 737, in PRI mode, if one is doing an approach in PRI mode, does the radio altitude show above the HSI or not. Also how often does the system update the track information? One more question: Since the 737-700 has a GPS reciever, does the HUD use it for navigation data instead of the IRS?. .Thanks for your help,. .Jon Gibbs. .p.S. the hud is availible at <a href="http://www.alliedfsgroup.com" target="_blank">www.alliedfsgroup.com</a> Also if any pilot interested in testing a new version of my HGS or my version of the 737-700 insturment panel for flight simulator please send me an email. jgibbs456@<hidden>
I usually use IMC or AIII mode for approaches. I do not have my manuals with me at home. But I think it is to the right of the HSI since altitudes are on the right and speeds are on the left. It is only visible below 2500 FT AGL.
>>Also how often does the system update the track information?<<
Flying with the HGS is like flying with the regular instruments.
The -700 uses the GPS to update the IRS.
Here is the rest of the answer.
A digital Radar Altitude is displayed directly below the Flight Path sysmbol. (about one inch below and it moves with the Flight Path sysmbol). The Radar Altitude value is removed from the display at 1500 feet when ascending and is again displayed at 1400 feet when descending. If the Flight Path sysmbol is not displayed, the Radar Altitude is displayed relative to the Aircraft Reference sysmbol.
The digital value is displayed in flight in ten foot increments between 50 and 1500 feet, five foot increments between 10 and 50 feet and one foot increments between -20 and 10 feet. Radar Altitude is not displayed on the ground.
