1971
CIVIL AVIATION ACT
The Civil Aviation Act of 1971 created the Civil Aviation Authority and the British Airways Board, the latter to function as a holding company for BOAC and BEA.
The Civil Aviation Authority would be given a broad remit to ensure that services met demand cheaply and profitably.

MINISTRY CHANGE
Another change affecting CAFU happened in January when the Board of Trade (BOT) merged with the Ministry of Technology to form the Department of Trade and Industry (DTI), which had come into being on the ....................., and now became responsible for Civil Aviation matters.

JOHN BOYD-CARPENTER
After the recommendations of the Edwards Committee on the Administration of Civil Aviation, was published, Ted Heath, Conservative Prime Minister, asked John Boyd-Carpenter to be Chairman of a proposed Civil Aviation Authority.  It will be remembered that .........................


NEW CAFU BUILDING
At last, CAFU staff were able to work in some comparative comfort when they moved into their newly completed building.   It was two-story in the shape of an ‘H’ (minus the bottom right-hand leg - see photograph).

NAVIGATIONAL AIDS
The network of en route navigation aids operational within the U.K., which CAFU were involved in flight inspection, had grown over the years.  By the end of 1971 there were:
      ..              NDB’s (20 en route).
     ..               VOR’s (including one DVOR).
     ..               DME (including some TACAN ranging elements).

CAT 3A ILS

In 1971 a BEA Trident 3B, with auto rudder control to steer the aircraft during ground roll, after touchdown to 80 knots, was provided with steering guidance for manual control below that speed, enabling CAT IIIA operations.

NAVAID INSPECTORS
There were six Navaid Inspectors (NAI’s).  Each flight inspection normally carried one NAI per flight together with an assistant.  The NAI made the assessments regarding the navaid being checked, liasing with the airfield Chief Telecommunications Officer as to the aids serviceability and certification.

NAVIGATORS
Who now undertook both navigation and the co-pilot duties, including the pre-flight preparation for flight inspections were still heavily engaged in post flight analysis of the results.

1972
UNDER NEW MANAGEMENT
In January it was announced that John Boyd-Carpenter would be the Chairman of the CAA.  Among the Board Members were R.R. Goodison, Deputy Secretary in the Department of Trade and Industry, Mr G.W. Stallibrass, mentioned earlier in Chapter Two and now the Controller of the National Air Traffic Services, and Professor D. Keith Lucas, professor of aircraft design at the Cranfield Institute of Technology and chairman designate of the Air Registration Board.  Mr Goodison would be acting as Chairman until .................................

AIRCAFT
During November two Telecommunication Doves, G-ALFU and G-AJLV were no longer registered as being with the CAA.  LFU had served 23 years and JLV, the first ever Dove registered to the MCA 25 years previously, as flight inspection aircraft, both checking landing & en-route navigational aids between the Channel Isles and Northern Scotland.  Both were ‘Permanently Withdrawn from Use’, although Dove G-ALFU can still be seen, resplendent in its old colours of white, red and black cheat-line, hanging, as if in flight, in one of the hangers at Duxford, a fitting tribute to the Calibration Unit of the fifties, sixties and early seventies.
Also in November of 72, the first Instrument Rating Dove registered to CAFU, G-ALVS, was also retired and ‘Permanently Withdrawn from Use’ (PWFU).  This IR Dove had been registered with the Ministry for .. years.
Eight months after the creation of the CAA the Flight Operations Directorate, under which CAFU was controlled, recognised the need to provide Examiner/Inspectors, as well as Flight Operations Inspectors, the necessary experience of operating an aircraft in an airline environment, particularly in light of the burden of ever more Air Operators Certificates (AOCs) being issued.  With this in mind the CAA purchased ................

ILS
1972 there were installed at U.K. airports:
    ..                 Category 1 ILS
    ..                 Category 2 ILS
    ..                 Category 3 ILS

AIRPORTS
Apart from the major Scottish airports, Edinburgh, Glasgow and Prestwick, that CAFU were concerned with, there were other Highland and Island airports also visited, all of which required Flight Inspection of their navigational and landing aids:

These airfields were also visited, ...............................................................

LICENSING
CAFU had conducted some ........... tests up to this period.
The number of professional pilots doubled from ..... to ..... between the period 196. to 197., an indication of the workload that CAFU Examiners had faced.

ACCIDENTS
The number of fatal accidents to U.K. scheduled flights between 1962 and 1972 almost halved.

CONCORDE
Although Capt John Oliver had attended the first Concorde Introductory Course during January 1969, it was not until this year that he attended the second introductory course at Bristol Filton.

1973
G-ATMJ which had joined CAFU at the end of last  year, had its first  flight  after conversion  in January.

MIDDLE EAST CONTRACT
Somewhere in the early 1970’s CAFU were approached, through DOSO, the Directorate of Operational Services Overseas of the DTI, to conduct Flight Inspections for a number of Middle Eastern Countries for both en Route and Landing aids.
Middle East Aids calibrated during this period:
  

ICAO
Since 1970, teams in five countries had worked on the best way of satisfying the AWOP (All Weather Operational requirements) operational requirement.  Though the ICAO requirement made no specific reference to microwave frequencies, most of the development teams chose to use this band.  But as far as ICAO was concerned, the new landing system could have been based on ‘foghorns and ear-trumpets’, wrote Flight magazine, just so long as the requirements were met.
Five states made initial submissions to ICAO in 1973.  These, with the techniques proposed, were:
·         ............. (TRSB)
·         ............. (FRSB)
·         ............. (DME-based landing system, DLS)
·         UK (commutated Doppler)
·         ............. (FRSB and commutated Doppler).

AIRCRAFT
G-ANAP, the Dove used in the 50’s and 60’s for Ordnance Survey work was taken off the register in August as PWFU.  NAP had been with CAFU for ...... years.

BRITISH AIRLINE SAFETY
Flight magazine asked the question, ‘
Has the creation of the CAA cured any deficiencies in liaison between the sections of the organisation that existed before?" ......................

CONCORDE

Capt John Oliver, the CAFU Flight Examiner chosen to be the Concorde Training Inspector, had several visits to Toulouse during this period, for demonstrations of various sorts on the Flight Test Development Simulator.

CAFU worked with the Education Department of the Essex County Council and provided Educational flights to children from schools in Essex.  Two hostesses were contracted to fly on each flight.
Pilot/Navigator Derek Carruthers, who had joined in 1947, can be seen ascending the steps.  He is reported to have given informative commentaries as they flew about 2,500ft around the Thames area.

1974
ICAO - MLS
The initial Working Group meeting set up to evaluate the technical submissions, was held at The ....... in March 1974, followed by a second in September of the same year.  The Working Group comprised ten members, eight of whom were considered to have sufficient expertise to judge the proposed techniques.  They came from Australia, Canada, France, West Germany,  the Netherlands, the UK, USA and USSR, and were joined by two delegates nominated by .......................... and the International Federation of Air Line Pilots Associations.  The Group was intended to work as a purely technical forum, free of ...................

TELECOMMUNICATION SECTION
They were still headed overall by a Superintendent.  The Navaid Inspectors who did all the flying were headed by a senior NAI, who no longer flew, or only when a situation dictated.
The Tels ground staff engineers each had their own sections and section heads.  There were four main functions for the Tels organisation as listed below.
         Workshop                            
         Calibration
         P and E      (Planning & Evaluation)                         
        Telecroscope              
There was an installation workshop, which was soon disbanded (in 1975).  It's responsibilities of installing Flight Inspection systems in Aircraft became less and less as the 748's settled down and the work was split .................................
There was also a technical Library, used for holding aircraft manuals, as well as the Tels department documentation.  The Tech Library was run by Jack Straw, father of the politician .......................................................... 
The Nav Aid Inspectors were both aircrew and Tels engineers, which enabled both sides, flying and ground staff, to work closely together.

VIP FLIGHTS
Northolt figured more this year, Ministers found it attractive as it was close to Heathrow but with far less problems with boarding and disembarkation due to this less busy RAF station.  Flights were going to ...........................................
Ministers flown by Capt Morgan were, Mr Peter shore (twice), Minister for Trade, Mr Tony Benn, Minister for Industry, Mr Peart (twice), Minister for Agriculture, Mr Peter Shore as Minister for Trade and later as Secretary for Industry.  Lastly, Mr Roy Hattersley, Secretary, Foreign and Commonwealth Affairs.

1975
CIVIL SERVICE CONTRACT
Most CAFU staff, who had been pressed for some time by the CAA with payment incentives, eventually terminated their contract with the Civil Service at the end of .......... 1975.  The new CAA terms and conditions were said to be similar, or as good as, the Civil Service — though only time would tell the changes to be implimented.

CHARTER
In May, the HS748, G-ATMJ, was being leased, to Dan Air.   It was picked up by Flight and reported, in their July 17th  magazine, that an HS748 of the Civil Aviation Flying Unit was operating weekend charters for Dan-Air .........................................

CONCORDE
Both Capt John Oliver and Geoffrey Packham, CAA FOI, attended the first British Airways Conversion Course at Bristol Filton on what was BA’s ‘nucleus course’.

CALIBRATION
There were now thought to be around ........ U.K. ILS installations in the U.K. which CAFU were currently Flight Checking.  By the early 1970’s CAFU had stopped checking  ....................

CAT 3B ILS
Clearance for Category 3B operations came in 1975, allowing ILS landings to be made with the visibility down to 330  feet (Runway Visual Range) and a 12 foot decision height.

CAA COSTS
In1975 inflation had been so high that the CAA difference between income and expenditure had expanded to £..m.  It was a dilemma that the Chairman, Lord Boyd-Carpenter, endeavoured to redress.  The CAA pushed out a paper to the industry proposing how costs ought to be applied.
Some of the charges suggested, which CAFU might have to apply, annually, were:
        Simulator Approvals       £....... 
        School Approvals           £.........
        Charges for (DE) Authorised Examiner course
        Senior Flight Examiner hourly charges to be £....
A Flight magazine leader called the proposed Simulator charges “Grotesque”,  and indusrty leaders responded ..............................

AUTOLAND DEVELOPMENT
Refinement of the landing ground-roll phase for BEA’s BAE21 Trident had now been completed (see Flight for ......., 1972) and the system was now ready for Category 3b operations (under which the pilot did not have to see the runway lights for any great distance ahead until the landing roll was almost complete).  In practice, zero visibility meant anything up to 25m, the first figure beyond zero on the RVR scale.

MANDATORY OCCURRENCE REPORTING SYSTEM (MORS)
A comprehensive Mandatory Occurrence Reporting System is introduced, ..........................

MINISTERS’ TRANSPORT
There were more questions asked in the House about Ministerial Flights on the 1st May, when Hansard reported the Prime Minister being asked what rules applied to the use by Ministers of military or other aircraft in the course of their duties, and what rules for repayment were applied in cases when such planes were used for unofficial purposes.
The Prime Minister replied:

CHAIRMAN
April saw the end of the five year term of the first Chairman of the CAA, Lord Boyd-Carpenter.  His replacement was Mr Nigel Foulkes, who reportdly, promptly declared, “Our job is to ............ — the Government thinks so and I heartily agree”.


OPERATIONS
Since CAFU’s inception Operations had traditionally been headed by an Operations Officer (OO) but, perhaps because of savings that the CAA were now trying to make, when Bernard Fitch the Ops OO retired, one of the senior Navigators, Sid Pritchard, was asked to take control.

CALIBRATION
The pressure of air traffic growth was restricting the accessibility of some airports.  At Heathrow, for instance, it was expected that it might soon be necessary to perform ILS calibrations at night.
Although not exactly calibration work, CAFU aircraft were engaged in trialling a Ground Proximity Warning device in one of the HS748s ................

The FAA was also having to face challenges from the British MLS development team, which maintained that Doppler MLS had fully lived up to expectations in the demonstrations and trials that had been completed since last June. A comment in Flight magazine: "If the previous week's House of Representatives hearing in Washington - which was primarily concerned with the Lincoln Laboratories simulations - generates more scepticism about FAA procedure, it is likely that the Administration would come under increased pressure to be more open about TRSB trial results.

HEAD ON COLLISION  -US MLS INQUIRY seeks "plain truth"
In January, representatives , from the US and Britain were testified before the US House of Representatives' transportation subcommittee, investigating accusations that the Federal Aviation Administration (FAA) deliberately misled the ICAO All Weather Operations Panel about microwave landing system (MLS) performance.

CATEGORY ‘C’ AIRFIELDS
Category ‘C’ airfields were considered difficult to arrive at, usually with high surrounding terrain and or many procedures.  The crew were not only briefed beforehand, but one of the crew members had to have flown into the airfield within the last six months.  After an accident at Tenerife North, where a UK B707 aircraft turned the wrong way in the holding pattern and crashed into high ground, CAAFU Inspectors flew the BAe125 to Lisbon, Tenerife North, Tenerife South, Madera, Gibraltar, Tarbes.  Not only were they able to check the pattern at Tenerife North, as well as the English spoken by ATC, but also took the opportunity to visit the other category ‘C’ airports on that route.  The flight was accomplished using the HS125 hours allocated to each Inspector.

CAFU COMPUTERS
Although the Telecommunication side were already using computers, this year the Administrative side were also supplied with an ICL CPM system.  The main server was held in the IRE/TRE office under the control of Sid Pritchard, Manager of Operations, who oversaw the introduction of Word Processing in several offices.  This arrangement led to the introduction of a computerised Flight Planning system used by Operations for the BAe125 flights.........................."

EUROPEAN JOINT AIRWORTHINESS REQUIREMENT (JAR)
The UK adopts the first European Joint Airworthiness Requirement, covering standards for large transport aircraft.
 
FCL
Until now, pilots wanting to be CAFU Examiners were required to have a CPL and an Instructor qualification to apply as a permanent FE2 grade, but with little or no prospect of being up-graded.
