Highway in the Sky (HITS)

Any EFIS system with Synthetic Vision is capable of displaying Highway in the Sky (HITS). HITS is the artificial

generation of boxes that direct the pilot towards a programmed navigation course set by the GPS. HITS is

depicted as magenta boxes in the synthetic vision. Waypoint names will also be displayed in the HITS box,

giving the pilot further information about their location on the flight plan.

Laterally, the HITS boxes will follow the GPS course programmed by the external GPS navigator or by the

internal flight plan. Vertically, HITS boxes are controlled by the altitude bug. If the altitude bug is reset to a

higher or lower altitude, ALL of the HITS boxes will move up or down to the altitude. A climbing or descending

path will not be displayed.

Enabling HITS

Press [EFIS] -> [AP/FD] -> [HITS ON| or [FD/HITS ON]

Disabling HITS

Press [EFIS] -> [AP/FD] -> [FD/HITS OFF] or [FD ON]

Flying with HITS

Flying with HITS involves positioning the aircraft so the flight path marker (green target) is in the center of the

HITS boxes. This will ensure the aircraft actually flies through the center of the boxes. The HITS boxes

themselves are 700ft wide by 200ft tall, so there is a very narrow margin to fly through.

Glidepath - HITS will display a glidepath to a chosen runway when setup to do so. To use this feature go to the

Flight Plan page (CHECK -> FLT PLAN) and enter a flight plan. Select a runway at the destination, select the

glide-angle, enter a crossing restriction and press ACTIVATE. HITS boxes will then be drawn at the prescribed

angle up from the runway selected to the altitude entered. For example, a 3 degree angle from RWY 35 at

KUAO up to 1,500ft MSL. The highest box will flash white, indicating Top of Decent.
