UPDATES TO FOURTH EDITION
These changes have been incorporated in the fifth edition
NOTAMS
Just after I went to press with the new edition, NATS changed the format of the NOTAMS slightly.
A new example is given below:
EGTT
NAVW: Q)EGTT/QWPLW/IV/M/W/000/040/5234N00052E003
FROM 06/04/27 16:30 TO 06/04/27 18:30 H0951/06
E) AUS 06-04-0394/1078/AS6
PJE WILL TAKE PLACE WI 3NM RAD OF 5234N 00052E(WATTON)
F)SFC G)4000FT AGL
The main change is that the code letters A, B, & C have now vanished.
EGTT means the London Flight Information Region
NAVW = navigation warning
The Q code is to assist software to process the NOTAM more easily
If an aerodrome were quoted, the ICAO aerodrome code would be given eg Barkston Heath is EGYE
The start and finish times which were prefixed by B and C then follow.
The H0951/06 and AUS reference numbers are followed by a description of the event (a parachute jump exercise) in section E
F) and G) give the lower and upper limits as before
The link given in book to the NOTAM page no longer works. Instead go to http://www.ais.org.uk/aes/login.jsp
, register and log in. Then choose NOTAM and VFR FIR Brief for EGTT (London) or EGPX (Scotland).

THE BRONZE PAPER
The BGA's new Bronze Papers are generated by a CD, but I have a few issues with these. These points have been carried over from
the updates for edition 3.
The questions include some questions which are of, at best, marginal relevance. (I have not seen all the questions so there may be others.) The topics are difficult to include in a coherent book, so I have alerted you here.
"Which method of reducing dip error in the magnetic compass (not Bohli type) is the correct one?" The answer is "to suspend magnets below the pivot".
"What is the principle of the gyroscope in the turn indicator?" The answer given is "If a turning force is applied to the gyro, the resultant movement will be 90 degrees from the initial force and in the direction of rotation"
"While flying in cloud you notice the ASI reading strangely such as showing less speed after the stick has been moved frowards (sic). What is the most likely cause?" The answer given is that there is ice in the pitot system.
The other choices are: water in the pitot system, ice in the static system or you are fully stalled. It is not sensible to provide enough information in Bronze & Beyond to diagnose problems with ASIs in flight.
"Approximately what proportion of the weight of a glider is supported by the lift from the upper surface of the wing?" Answer given 80-110%. It is possible to measure the pressure at various points on a wing and draw a graph of the
pressure above and below the wing at various places along the chord, ie from the leading edge to the trailing edge. This graph indeed shows that most of the pressure differences at positive angles of attack comes from above the wing.
See graphs of pressure distribution However the percentage quoted is highly unreliable. It is also debatable that this question has any relevance
Some answers are just plain wrong. I have contacted the BGA and I have also pasted in my comments below

OXYGEN
The General Aviation Safety Information leaflet in June 2006 stated that a future amendment to the
Air Navigation Order is expected to make it mandatory for private flights to carry such a serviceable system if flying above FL130, or if flying
between FL100 and FL130 for more than 30 minutes, and for the crew to use it in these circumstances.
However the ANO has not yet been amended. The latest version, dated October 2006, states on page 192-103
that "In any other flying machine (other than pressurised aircraft)
.....the flight crew shall be supplied with oxygen sufficient for continuous use for any period during which the flying
machine flies above flight level 100". CAP393

RIGHT OF WAY
I am grateful to Andrew Watson for pointing out an error. Gliders have to give way to balloons but
not to airships. (Powered aircraft have to give way to both.)

CLASS C LOWERING
Class C airspace will be lowered to FL195 on 15 March 2007. Gliding above FL195 can only occur in Temporary Reserved
Areas (gliding) [TRA (G)], which must be activated by ATC. IFR flight will not be permitted in an activated TRA
(G). With the exception of the TRA (G)s located in the Aboyne area, TRA (G)s will generally only be available at a
weekend or on a public holiday. Check with the local club for the precise regulations in the area.
