Have you ever thought about the roots of the term 'Roger' in aviation language? Long ago, Morse code was used for distance communication. In this dot-and-dash language, the letter 'R' meant “Received." As technology advanced, the aviation world began adopting radios. These early versions were, unsurprisingly, not as crystal-clear as our modern equipment. Clarity was paramount; miscommunication, even by a single letter, could spell disaster. Enter the phonetic alphabet of the 1920s, where "Robert" stood for the letter 'R'. However, by the time of World War II, this had evolved to “Roger.” By using "Roger" in voice communications, aviators were effectively echoing the Morse code's message of "Received." Fast forward to today, our communication devices have become infinitely more sophisticated, yet the term "Roger" firmly holds its ground. 🔴More content alike @AEROEDGE

AERODROME REFERENCE CODE (ARC) 🔶The intent of the aerodrome reference code is to provide a simple method for interrelating the numerous specifications concerning the characteristics of aerodromes so as to provide a series of aerodrome facilities that are suitable for the aeroplanes that are intended to operate at the aerodrome. 🔸The code is not intended to be used for determining runway length or pavement strength requirements. 🔸The code is composed of two elements which are related to the aeroplane performance characteristics and dimensions. 📌Element 1 is a number based on the aeroplane reference field length 📌Element 2 is a letter based on the aeroplane wingspan. 🔸The code letter or number within an element selected for design purposes is related to the critical aeroplane characteristics for which the facility is provided. 📎E.g: OIMM ARC IS 4E BASED ON IRAN AIP/AD/AD2/OIMM 🔴More content alike @AEROEDGE

Assessing and Expressing Levels in Flight 🔶An aircraft’s vertical position is expressed as: • Altitude, using QNH, at or below the transition altitude • Flight level, using SPS, at or above the transition level 🔶Within the transition layer, levels are expressed as: • Flight levels in the climb and • Altitudes in the descent 📌SPS: STANDARD PRESSURE SETTING 🔴More content alike @AEROEDGE

⭕️❗️Failure or irregularity ❗️⭕️ 🔶Aerodrome control tower shall immediately report in accordance with local instructions any failure or irregularity of operation in any equipment, light or any other device established at an aerodrome for the guidance of aerodrome traffic and flight crews or required for the provision of air traffic control service. 🔴More content alike @AEROEDGE

🔶CONDITIONAL CLEARANCES🔶 🔸Conditional clearances shall not be used for movements affecting the active runway(s), except when the aircraft or vehicles concerned are seen by both the controller and pilot. 🔸When the conditional clearance involves a departing aircraft and an arriving aircraft. 🔸It is important that the departing aircraft correctly identifies the arriving aircraft on which the conditional clearance is based. 🔸Reference to the arriving aircraft type may be insufficient and it may be necessary to add a description of the colour or the company name to ensure correct identification. 🔸A conditional clearance shall be given as follows: 1) call sign 2) the condition 3) the clearance 4) brief reiteration of the condition. 📌This implies the need for the aircraft receiving the conditional clearance to identify the aircraft or vehicle causing the conditional clearance. 🔴More content alike @AEROEDGE

❄️COLD TEMPERATURE CORRECTION❄️ 🔶Temperatures lower than those of the standard atmosphere result in the actual altitude of an aircraft being lower than that indicated by the barometric altimeter. 🔶 As a consequence, the MOC actually achieved could be lower than the prescribed MOC. 🔶In order to prevent this, the pilot shall correct for low temperatures. The pilot is responsible for any necessary cold temperature corrections to all published minimum altitudes/heights in both conventional and PBN procedures. 📌This includes: 🔸the altitudes/heights for the initial and intermediate segment(s) 🔸the decision altitude/height (DA/H) or minimum descent altitude/height (MDA/H) 🔸subsequent missed approach altitudes/heights. 🔴More content alike @AEROEDGE

🔶An Introduction To STAR🔶 🔸A standard instrument arrival (STAR) route permits transition from the en-route phase to the approach phase. 🔸When necessary or where an operational advantage is obtained, arrival routes from the en-route phase to a fix or facility used in the procedure are published. This is normally the initial approach fix (IAF). 🔸Omnidirectional or sector arrivals can be provided taking into account minimum sector altitudes (MSA). 🔸MSAs are established for each aerodrome and provide at least 300 m (1 000 ft) obstacle clearance within 46 km (25 NM) of the significant point, the aerodrome reference point (ARP) or the heliport reference point (HRP) associated with the approach procedure for that aerodrome. 🔴More content alike @AEROEDGE

❗️Phases of Missed APCH❗️ 🔶The initial phase begins at the MAPt and ends at the start of climb (SOC). This phase requires the concentrated attention of the pilots on establishing the climb and the changes in aircraft configuration. It is assumed that guidance equipment is not extensively utilized during these manoeuvres, and for this reason, no turns are specified in this phase. 🔶The intermediate phase begins at the SOC. The climb is continued, normally straight ahead. It extends to the first point where 50 m (164 ft) obstacle clearance is obtained and can be maintained.The intermediate missed approach track may be changed by a maximum of 15° from that of the initial missed approach phase. 🔶The final phase begins at the point where 50 m (164 ft) obstacle clearance is first obtained and can be maintained. It extends to the point where a new approach, holding or a return to en-route flight is initiated. Turns may be prescribed in this phase. 🔴More content alike @AEROEDGE

📌Accuracy of Fixes and Fix-Tolerance Factors for Conventional Approaches 🔶The general criteria for conventional approaches using ground-based navigational guidance is influenced by the accuracy of fixes caused by the tolerances of: 🔸 Ground systems 🔸Airborne receivers 🔸 Flight technicalities 🔶This means that any conventional geographic point identified by using traditional navigation aids, such as very high frequency omnidirectional radio range (VOR), instrument landing system (ILS), and non-directional beacon (NDB), is not precise, but instead is located within a fix-tolerance area. 🔴More content alike @AEROEDGE

🔶Introduction to Fronts🔶 🔸A front is a zone or boundary between two air masses of different temperature. 🔸When the two air masses meet, the warmer will rise over the top of the colder because of the difference in density. 🔸The frontal surface where they meet is frequently active with much cloud and precipitation. The ground position of the frontal surfaces, also known as surface front, is or surface pressure charts. 🔸A front is usually only a few miles wide. If the term frontal zone is used, then the region of interaction is much wider (up to 300 NM). 🔴More content alike @AEROEDGE

🔶Runway condition assessment matrix (RCAM)🔶 📌means a matrix that allows the assessment of the runway condition code (RWYCC) using associated procedures, from a set of observed runway surface condition(s) and pilot report of braking action. 🔶Runway condition code (RWYCC)🔶 📌means a number, to be used in the runway condition report (RCR), that describes the effect of the runway surface condition on aeroplane deceleration performance and lateral control. 🔴More content alike @AEROEDGE

🔶INTERMEDIATE APPROACH SEGMENT 🔶 🔸This is the segment during which the aircraft speed and configuration should be adjusted to prepare the aircraft for final approach. For this reason, the designed descent gradient is kept as shallow as possible. To fly an efficient descent profile, the pilot may elect to configure the aircraft while in a continuous descent along this segment. 🔸Where a FAF is available, the intermediate approach segment begins when the aircraft is on the inbound track of the procedure turn, base turn or final inbound leg of the racetrack procedure. It ends at the FAF or final approach point (FAP), as applicable; Where no FAF is specified, the inbound track is the FAS. 🔸During the intermediate approach, the obstacle clearance requirement is 150 m (492 ft) in the primary area, reducing laterally to zero at the outer edge of the secondary area. 🔴More content alike @AEROEDGE

PROVISION OF ATS SURVEILLANCE SERVICES 🔶Information derived from ATS surveillance systems, including safety-related alerts and warnings such as conflict alert and minimum safe altitude warning, should be used to the extent possible in the provision of air traffic control service in order to improve capacity and efficiency as well as to enhance safety. 🔶The number of aircraft simultaneously provided with ATS surveillance services shall not exceed that which can safely be handled under the prevailing circumstances, taking into account: 🔸the structural complexity of the control area or sector concerned. 🔸the functions to be performed within the control area or sector concerned. 🔸assessments of controller workloads, taking into account different aircraft capabilities, and sector capacity. 🔸the degree of technical reliability and availability of the primary and backup communications, navigation and surveillance systems, both in the aircraft and on the ground. 🔴More content alike @AEROEDGE

⚡️Thunderstorm Motion ⛈ 🔸A thunderstorm is a process, not a solid object or block of wood. Storm motion equals the combined effects of both advection and propagation. Advection is the component of storm motion due to individual cells moving with the average wind throughout the vertical depth of the cumulonimbus cloud. 🔸The wind at FL180 (500 mb) usually provides a good approximation. Propagation is the component of storm motion due to old cell dissipation and the new cell development. Storm motion may deviate substantially from the motion of the individual cells, which comprise the storm. 🔸Individual cells that comprise the storm move northeast (advection), but dissipate and are replaced by new cells (propagation). Storm motion equals the combined effects of both advection and propagation. 🔴More content alike @AEROEDGE
