Up Front Controller The Up Front Controller was introduced in the A-10C so that important settings can be made quickly without having to look too far away from the HUD. It is a control unit whose buttons control and input of settings to other cockpit units. For the F/A-18C this concept has been extended so that entries can only be made via the centrally located UFC. | ||

3 OFFs | ||
---|---|---|
Bearing Off, Distance Off, Time Off A method of checking leg tracking and timing at the mid leg check point during navigation BEARING OFF - At your mid leg check point assess your location compared to the check point and estimate the difference in bearing from the start waypoint. DISTANCE OFF - Estimate the Distance Off of track using the 1 in 60 Rule. TIME OFF - Note hoe the time abeam the check point compares to the planned time From these three Offs the aircraft can be flown back onto track or flown directly to the end leg waypoint. Also an assessment of the time of arrival at the leg end waypoint can be made or the aircraft speed changed to maintain a time over the waypoint. | ||

Attitude Indicator The main instrument of understanding the aircraft‘s attitude with respect to earth’s surface. It is a gyro (or graphical representation) driven by either:
It is normally mounted centrally on an aircraft main instrument panel. It can be implemented as graphics within a “glass cockpit”. Further Information: Wikipedia | ||
APT | ||

Attitude, Power, Trim A method specifically for levelling off from a climb. ATTITUDE - Pitch from the Climb attitude to the Straight and Level attitude expected for the required speed. POWER - Adjust the throttle to provide the expected power required for the desired speed. TRIM - Trim the aircraft in pitch to minimise stick forces so the aircraft maintain the chosen attitude wits minimal input from you. See also: PAAT | ||

Clock Code | ||
---|---|---|
Clock Code This has two meanings depending upon its application. Lookout - When applied to Lookout, Clock Code is a method of identifying an azimuth direction from the aircraft. Directions from the aircraft begin from 12 O’clock being directly ahead with 6 O’clock being directly astern. E.g. 4 O’clock indicates a direction past the abeam on the right side of the aircraft. Drift - When applied to Drift, Clock Code is a method of mental arithmetic to estimate the Sin() function. The difference between the wind direction and the aircraft‘s flight path is compared to minutes of a clock. The resulting potion of the hour is the portion of Max Drift to be used to estimate the angular correction to make to offset the aircraft‘s heading and so allow for drift, thus keeping the aircraft on track. E.g. 30˚ implies 30 minutes which is half an hour and so half the Max Drift should be applied towards the wind for the aircraft to maintain the desired track. | ||
HAT | ||
---|---|---|
Heading, Altitude, Time A method of conducting a turn at a waypoint during navigation. This occurs twice, Before the turning point is the Pre-HAT and after the turning point is the Post-HAT Pre-HAT HEADING - Having seen the turning point (or planning to turn on time) Check the next heading from your navigation plan. Adjust this heading for drift using Max Drift and Clock Code. ALTITUDE - Check if there is a required change of altitude for the next leg and the associated Safety Altitude. TIME - If running individual leg timing, reset the clock. If running continuous timing for the route, note the time at the waypoint. At the waypoint, Restart the clock (if required), Lookout and Turn.... JUST Lookout and Turn until rolling out on heading. Do NOTHING else. Post-HAT HEADING - After rolling out, check you have rolled out on your wind adjusted heading. ALTITUDE - Adjust your altitude for the next leg. TIME - Ensure the clock is running or if you forgot to note the time at the waypoint take the time now and add a few second for the turn.
