CAP 413 Radiotelephony Manual
Chapter 6 Page 24
1.11.6 When the SRA terminates at 2 miles from touchdown the advisory level checks at half
mile intervals are omitted and pilots are expected to reply to all transmissions from
the ground station.
1.11.7 Altitude/height checks below the category A aircraft OCA/OCH will be omitted.
1.11.8 The equivalent military SRA phraseology appears in Chapter 10 paragraph 3.12.
1.12 Landing Altimeter Setting (QNE)
QNE is the indication which the altimeter will give on landing, at a particular time and
place, when the hectopascal scale is set to 1013.2 hPa. QNE information may be used
by pilots of aircraft whose altimeters cannot be set to below 950 hPa. The QFE/QNE
conversion will be calculated by ATC.
Example: QFE 947.6 Set 1013.2 on altimeter
Altimeter will read 1842 ft on touchdown
1.13 PAR Approach
1.13.1 Pilots visiting military airfields may wish to undertake a PAR Approach (Precision
Approach Radar). An explanation of the phraseology used by military pilots and
controllers appears in Chapter 10 paragraph 3.11 and following sections.
1.14 Clearance to enter Control Zones (CTR)
1.14.1 The majority of CTRs in the UK are designated Class D airspace, which permits VFR
flight subject to an ATC clearance. In the case of a CTR designated Class A airspace,
a Special VFR (SVFR) clearance is required if the aircraft is being flown visually. See
paragraph 1.5.
