evaporation is least and north-westerly winds prevail. See also

Tides, —In the
Persian gulf
The historical term used to describe the body of water between the Arabian Peninsula and Iran.
, great variations occur in the type
of tide, and the information available is insufficient for any reliable
general description to be given; tides of semi-diurnal type appear, 5
however, to be usual in the northern part of the Gulf, and tides
of diurnal type, in the southern part. Times and heights of high
water at the more important ports and anchorages may be obtained
from the information given in the Admiralty Tide Tables.
Tidal streams. —On the southern part of the south-western lO
side of the Gulf of 'Oman, the tidal streams are almost
imperceptible.
On the Makran coast, from Karachi to Gwatar, the tidal stream
sets eastward during the rising, and westward during the falling
tide; but westward of Gwatar bay it sets westward during the rising, 15
and eastward during the falling tide.
In the northern part of the Gulf of 'Oman, the general set of the
stream is north-north-westward and south-south-eastward. The
north-north-west-going stream attains a rate of from half a knot
to 2 knots, and is strongest on the western side, as Ras Musandam 20
is approached. The south-south-east-going stream attains a rate
of from one to If knots.
In the
Persian gulf
The historical term used to describe the body of water between the Arabian Peninsula and Iran.
, the tidal streams are subject to great variation
in type, semi-diurnal streams occurring in some parts, and diurnal
streams in others. The type of stream in any locality is not 25
necessarily the same as the type of tide, and diurnal streams may
occur where the tide is semi-diurnal, and vice-versa. For this
reason, the time of the turn of the stream, and its rate, in any
locality, bear no fixed relation to the tide in that locality. See
also pages 292 to 296, 30
Information available regarding the streams depends, generally,
on a few hours' observations only, and conclusions drawn by the
observers, though correct at the time, may be quite erroneous during
other astronomical conditions. Information regarding tidal streams,
given on the charts, must therefore be regarded as unreliable, and 35
used with caution.
Northward of Ras al Kuh, the streams become very strong, and
they attain their greatest rate, of about 4 knots and probably more
at springs, at Ras Musandam, where eddies and races are formed
near that point and between it and the Salamah wa Binat-ha islets, 40
On the eastern shore of the entrance of the Gulf, the rate of the streams
is less, and is perhaps from 2 to 3 knots off Girau. See also page 292,
SIGNALS.—Aircraft in distress, —When any aircraft is in
distress and requires assistance, the following shall be the signals
displayed by her, either together or separately:—■ 45

telegraphy, or in the case of radio-telephony, the spoken
word "Mayday",
2, The International code signal of distress indicated by N,C,
3, A distant signal consisting of a square flag, having above or 50
below it a ball or anything resembling a ball,
4, A continuous sounding with any sound apparatus.
5, A signal consisting of a succession of white pyrotechnical

- Extent and format
- 199 folios
- Arrangement
The pilot is arranged into eight chapters (I-VIII) and five appendices (I-V). The arrangement of chapters is geographical, moving from the easternmost point of the Gulf in chapter II to the westermost point in chapter VIII. The contents page (ff 7-8) and alphabetically ascending index (ff 182-93) refer to the pilot’s pagination system.
- Physical characteristics
Foliation: There is a foliation sequence, which is circled in pencil, in the top right corner of the recto The front of a sheet of paper or leaf, often abbreviated to 'r'. of each folio. It begins on the front cover, on number 1, and ends on the inside of the back cover, on number 199.
Pagination: There are two printed pagination systems, which generally situate numbers in the top-left corner of versos and the top-right corner of rectos. The first, which uses Roman numerals, runs through the pilot’s introductory pages (ff 6-19). The second pagination system uses Arabic numerals, and runs through the remainder of the pilot (ff 23-197).
The number of each chapter is indicated throughout the chapter (expressed as ‘Chap.’ and the chapter number as a Roman numeral) in the top-left corner of rectos and the top-right corner of versos. The lines of text on each page in each chapter are numbered in intervals of five (i.e. 5, 10, etc.)
