STAR Tutorial

  • The map below features some of the Standard Terminal Arrival Routes's (STAR's) for EGLL London Heathrow.
  • The EGLL STAR's are for the two parallel runways 09R/27L - 09L/27R (represented by purple near center).
  • The STAR's are named after their arrival point. All the arrival points below are VOR stations with the exception of TOMMO which is a Fix.
  • The red H are the holding points en-route.
  • Clockwise from the top they are:-
    • Lambourne (yellow) - for E/NE arrivals.
    • Biggin (orange) - for E/SE/S arrivals.
    • Ockham u/s (yellow) - for S/SW arrivals (u/s denotes upper airspace).
    • TOMMO (blue) - for W arrivals.
    • Bovingdon (green) - for NW/N arrivals.
    • Ockham (white) - for lower airspace arrival.

  • Aircraft are expected to arrive at 7,000ft which is the Mimimum Holding Altitude over London and speed limits etc.
  • Lambourne
    • LOGAN > TRIPO > BRASO > LAM
    • The LOGAN Fix (rightmost to north) is the entry point and also the entry point for a Biggin arrival.
    • The path is a direct radial between LOGAN and LAM with TRIPO and BRASO as convinient fix's
    • LOGAN and TRIPO are holding points.
  • Biggin
    • LOGAN is an entry point for Biggin and Lambourne arrival
      • LOGAN > KOPUL > TANET > DET > BIG
      • DVR > SANDY > BIG
      • DVR > SANDY > TIGER > BIG
      • ALESO > TIGER > BIG
  • Ockham u/s
    • U/S denotes upper airspace arrival
      • KATHY > HAZEL > OCK
      • GIBSO > ELDER > HAZEL > OCK
      • SAM > HAZEL OCK
  • TOMMO
    • TOMMO is a fix and part of the Ockham holding pattern
      • NIGIT > TOMMO
      • KENET > TOMMO
      • HON > TOBID > SOPIT > WCO > TOMMO
  • Bovingdon
    • KENET > DONNA > BOV
    • HON > TOBID > SPOIT > WCO > BOV
    • LAM > DONNA > BOV
  • Ockham in white
    • This is "lower level" arrival.
      • LAM > DORKI > OCK
      • BIG > DORKI > OCK


LONDON HEATHROW via BOVINGDON

  • The BNN STAR is for flights arriving from the north (eg X atlantic flights)
  • The Bovingdon Stack over the BNN vor, ready for Initial Approach to Heathrow. BNN is about 30km north off Heathrow and also the LON vor transmitter.

There are three simplified STAR's shown below followed by general info:

BNN 4A - yellow

BNN 4A Arrival via L10 (FL190 & below), N615 (FL90 to FL140) to HON VOR continue on HON VOR R142 to TOBID 
then SOPIT (FL150 by SOPIT) to WCO NDB then turn left onto BNN VOR R299 to BNN VOR.

BNN 1C - orange

Arrival via A47 (FL70) to DTY VOR continue on DTY VOR R166 to WCO NDB then turn left onto BNN VOR R299 to BNN VOR.

BNN 1E in green

From LAM VOR maintain LAM VOR R278 to DONNA then turn right onto inbound holding track 119°M to BNN VOR.

General Information

1 Standard Routes may be varied at the discretion of ATC.
2 Cross SLPs or 3 min before holding facility at 250KIAS or less.
3 When BNN VOR is out of service the route will be to BOVVA, see AD 2-EGLL-7-4.
4 En-route holding at HON VOR: During periods of congestion in the London TMA traffic 
  from the north may be required to hold at HON VOR.
5 As lowest level in BNN holding stack (7000) is above transition altitude, aircraft 
  will be instructed by ATC to fly at the appropriate flight level.

BNN 4A with comment

BNN 4A Arrival via L10 (FL190 & below), N615 (FL90 to FL140) to HON VOR continue on HON VOR R142 to TOBID 
then SOPIT (FL150 by SOPIT) to WCO NDB then turn left onto BNN VOR R299 to BNN VOR.
  • Flight ac001 (787) has passed the TOBID fix, heading 142, descending and slowing. Needs < 230 knots and at 15,000 by SPOIT fix ahead, before turn at WCO to BNN and IAF.

BNN 4A Arrival

  • BNN 4A is the "official CAA published name" of this route. It would appear on the "filed" FlightPlan.

via L10 (FL190 & below)

  • L10 is an airway and the leftmost brown line top left.
  • The aircraft needs to flying under 19,000ft (FL190)

N615 (FL90 to FL140)

  • N615 is an airway and the middle brown line on the top left
  • The aircraft needs to be flying on this leg FL90 and FL140

to HON VOR

  • from either of the arrival routes above, the aircraft needs to cross over Honiley vor transmitter

continue on HON VOR R142

  • then fly away from the transmitter heading south east on the 142 radial which is also the heading

to TOBID

  • TOBID is a fix on the path

then SOPIT (FL150 by SOPIT)

  • SOPIT is a fix on the path
  • the aircraft needs to be at 15,000ft by this point

to WCO NDB

  • Wescott is a Non Directional Beacon (NDB) on 335
  • and also the intersection of the HON 142 and BNN 299 radials

then turn left onto BNN VOR R299

  • over Wescott NDB turn left towards the 299 radial from Bovingdon - heading 119
  • the speed restriction ahead is < 250 (note 2)

to BNN VOR.

  • The red loop is the Bovington Stack holding point - the bottom of the stack is 7,000ft (note 5)
  • keep heading towards the BNN vor station
  • BNN is the IAP (Initial Approach Fix) for EGLL
  • The BNN Initial approach is shown in white

BNN 4A Cockpit View

  • The Autopilot is engaged (green AP ENG top PFD) and commanding the aircraft speed, heading (SPD, HNG, ALT in green top of PFD).
  • The nav display Range (R) is set on the glareshield knob to 80nm, displayed left of nav display.
  • The intersection of the arrows is around 20nm ahead.
