HOLD-SHORT POSITION LIGHTS (P/CG) - Flashing in-pavement white lights located at specified hold-short points. HOLD-SHORT POSITION SIGNS (P/CG) - Red and white holding position signs located alongside the hold-short point. HOMING (P/CG) - Flight toward a navigational aids, without correcting for wind, by adjusting the aircraft heading to maintain a relative bearing of zero degrees. (See Bearing) HOMING (JCS, NATO) - The technique whereby a mobile station directs itself, or is directed, toward a source of primary or reflected energy or to a specified point. HOMING (ICAO) - The procedure of using the Direction Finding equipment of one radio station with the emission of another radio station, where at least one of the stations is mobile, and whereby the mobile station proceeds continuously towards the other station. HOVER CHECK - Used to describe when a helicopter/Vertical Take-off Landing aircraft requires a stabilized hover to conduct a performance/power check prior to hover taxi, air taxi, or take-off. Altitude of the hover will vary based on the purpose of the check. HOVER TAXI - Used to describe a helicopter/Vertical Take-off Landing aircraft movement conducted above the surface and in ground effect at airspeeds less than approximately 20 knots. The actual height will vary, and some helicopters may require hover taxi above 25 feet above ground level to reduce ground effect turbulence or provide clearance for cargo slingloads. (See Air taxi, Hover Check) HOW DO YOU HEAR ME? - A question relating to the quality of the transmission or to determine how well the transmission is being received. IDENT - A request for a pilot to activate the aircraft transponder identification feature. This will help the controller to confirm an aircraft identity or to identify an aircraft. IDENT FEATURE - The special feature in the Air Traffic Control Radar Beacon System (ATCRBS) equipment. It is used to immediately distinguish one displayed beacon target from other beacon targets. (See Ident) IF FEASIBLE, REDUCE SPEED TO (SPEED) - (See Speed Adjustment) IF NO TRANSMISSION RECEIVED FOR (TIME) - Used by Air Traffic Control in radar approaches to prefix procedures which should be followed by the pilot in event of lost communications. (See Lost Communications) IFR AIRCRAFT/IFR FLIGHT - An aircraft conducting flight in accordance with Instrument Flight Rules. IFR CONDITIONS - Weather conditions below the minimum for flight under Visual Flight Rules. (See Instrument Meteorological Condition) IFR DEPARTURE PROCEDURE - (see IFR Take-off Minimums and Departure Procedures) IFR MILITARY TRAINING ROUTES (IR) - Routes used by the Department of Defense and associated Reserve and Air Guard units for the purpose of conducting low-altitude navigation and tactical training in both IFR and VFR weather conditions below 10,000 feet Mean Sea Level at airspeeds in excess of 250 knots indicated airspeed. IFR TAKEOFF MINIMUMS AND DEPARTURE PROCEDURES - Federal Air Regulations, Part 91, prescribes standard take-off rules for certain civil users. At some airports, obstructions or other factors require the establishment of nonstandard take-off minimums, departure procedures, or both, to assist pilots in avoiding obstacles during climb to the Minimum Enroute Altitude. These airports are listed in National Ocean Service/Department of Defense Instrument Approach Charts (IAPs) under a section entitled "IFR Takeoff Minimums and Departure Procedures." The National Ocean Service/Department of Defense Instrument Approach Procedure chart legend illustrates the symbol used to alert the pilot to nonstandard take-off minimums and departure procedures. When departing IFR from such airports, or from any airport where there are no departure procedures, Standard Instrument Departures, or Air Traffic Control facilities available, pilots should advise Air Traffic Control of any departure limitations. Controllers may query a pilot to determine acceptable departure directions, turns, or heading after take-off. Pilots should be familiar with the departure procedures and must assure that their aircraft can meet or exceed any specified climb gradients. |
