Of one Declination entry and that for the next higher degree, and is used Interpolation for Declination is required to establish the exact calculatedДЄltitude Difference (d) or вЂdвЂ™ is the difference of Altitude in minutes of arc LHA and the exact DR/EP Latitude can be resolved by plotting,

Tabulated Altitude (Hc) results from using вЂround-figureвЂ™ integer arguments Tabulated Altitude (Hc) and Azimuth Angle (Z) obtained require further interpolation, Provides Tabulated Altitude (Hc), Altitude Difference (d) and Azimuth Angle (Z). A horizontal line in the table shows theД. Read from the BOTTOM ) are always in the range from180В° to 90В°ДЄnd 180В° to 270В° for Latitude and Declination of the SAME Right-hand pages ( LHA read from the TOP ) areДЄlways in the range from 0В° to 90В° and 360В° to 270В°, for LatitudeДЄnd Declination CONTRARY name. Left-hand pages always show LHA s in the range ofД В° to 90В° and 360В° to 270В°, for Latitude and Declination of the To save space, the tablesДЄre arranged to allow this multiple application. PZX triangles can be solved using the same table. It can be shown (see Para 0542e) that up to four вЂdifferentвЂ™ The tables arrange the arguments as follows: Extract of Double-Page from NP 401 Showing Arrangement of Arguments An extract of a doublepage from NP 401 is at Fig 5-7 opposite, and showsДЇig 5-7. The tables make this conversion to provide convenient entry arguments for the Triangle (see Para 0531 and Fig 5-5), Co-Latitude and Co - Declination are, and Whilst neither Latitude nor Declination are sides of the PZX (to the nearest whole degree) of Local Hour Angle (LHA), followed by Latitude ,ДЄnd either Declination ( SAME name as Latitude ) or Declination ( CONTRARY 5. The tables are entered with the Tabulated (or Calculated ) arguments NP 401 is normally used with the Sight Form (NP 400 or NP 400a) to simplifyД«.

Each volume contains full user instructions and to avoid confusion with these, the terms Azimuth Angle (Z) and True Bearing (Zn) will be used when explaining NP 401 in this section. US/UK publication) uses the US notation and abbreviations of Azimuth Angle (Z) and Azimuth (Zn) to mean what is known in the RN as Azimuth and True Bearing respectively (see Para 0536). Volume overlap those of the preceding and succeeding volumes. However, each volume is arranged in twoДЁ-degree sections (or zones) of Latitude thus the first and last Latitude in each The tables are arranged in six volumes, each These tables (NP 401) provide computed values ofДЄltitude and Azimuth for arguments of Latitude, Hour Angle and Declination Explanation of Marine Navigation Sight Reduction Tables (NP 401 series).ДЄ. NAVPAC 2 User Instructions is at Annex 3A.Д 542. Reduction calculations are at Chapter 3, and an extract of HM Nautical Almanac OfficeвЂ™s

Generally calculate an Observed Position to an accuracy of 1 nautical miles,ДЄlthough this could increase to 2 nautical miles in certain circumstances.Дetails of the procedures for using NAVPAC 2 on a Windows-based PC for sight Precision of the ephemeral data entered and the capability and use of theД¬oncise Nautical Almanac Reduction Tables. NAVPAC 2 (ie within 0 nautical miles) but will in practice depend on the The potential accuracy of these formulae is comparable to Nautical Almanac Formulae and Procedures for Programmable Calculators. NP 303 will generally calculate an Observed Position to an accuracy of 0.

Vol 1 of NP 303Д¬overs all Latitude s and is the only volume of the series used within the RN. Generally calculate an Observed Position to an accuracy between 0 and 0.ДЄir Navigation Sight Reduction Tables (NP 303 series).

Passage and Polaris calculations are at Para 0348 and Chapter 6. (except for NAVPAC 2 which is at Chapter 3) are Paras 0541-0546. Details of the procedures for each method Summary of Methods Available for Sight Reduction and their AccuraciesДЇive methods for sight reduction calculations are available to the mariner theirДЄccuracy and the degree of labour involved vary.
