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 | ||||

Charlie Time The planned landing time on a vessel. Often also used for landing ashore. Usually the expected end of the sortie. | |||

Chicken Fuel The minimum fuel required to continue the route as planned. | |||
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. | |||

The Exhaust Gas Temperature of a jet engine is one of two primary measurements of engine performance. The temperature is usually measured at the Power Turbine that drives a shaft through the centre of the engine to spin the blades of the multi-stage compressor. Additional Information: | |||
FEEL | |||
---|---|---|---|
Fuel, Engine, Electrics, Location A method of ensuring the aircraft has sufficient fuel for the task, is operating correctly and that you know where you are. All AircraftFUEL - Check the quantity against the expected quantity at that stage of the flight. Consider this as an amount up or down and compare that to the wind you have experienced so far. Also ensure that the fuel tanks are in balance and correct with fuel transfer if needed. ENGINE - Check the engine instruments for any fluctuations or unusual readings. ELECTRICS - Check the generator is providing charge to the battery. LOCATION - Check your location is as you expect and you know where the nearest air station is in the case of an emergency. Modern AircraftThe additional systems of a modern aircraft often require a little more than just the above FEEL. Consider this as FEEL+ and can include things like: HYDRAULICS - Check the Temperature and Pressure OXYGEN - Check the contents, flow and pressure CABIN - Check the Pressurisation and Temperature Combat SituationsAgain, Combat situations may require further checks, see Fence In and Fence Out RepetitiveThese checks should be conducted about every 20 mins (as a minimum after each 30 mins) or after each change of altitude or turning point of a navigation exercise. | |||
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.
