13 / 20

Refer to Amsterdam 10-3V chart from the Jeppesen GSPRM 2017.
The MSA is...

  • A

    1 700 ft clockwise between Radials 117° and 356°.

  • B

    1 700 ft clockwise between Radials 177° and 130°.

  • C

    1 700 ft clockwise between Radials 176° and 297°.

  • D
    1 700 ft clockwise between Radials 297° and 176°.

Refer to figure.
Minimum Sector Altitude (MSA) is the lowest altitude in feet which provides a minimum vertical clearance of 1000 ft above all obstacles in an area contained within a circle of 25 NM radius centred on a ground navigational aid. MSA may be given as one value or could be divided into sub-sectors, each sector having a different value.

On a Jeppesen SID chart, MSA is depicted in maroon colour.

On the AMSTERDAM (EHAM) SID 10-3V chart, the MSA is divided into two sub-sectors by two magnetic bearings to the station (QDM) VOR/DME SPL: 357o and 310o.

If subtracted by 180o, the two bearings to the station VOR/DME SPL will be converted into Radials (QDR) and they become correspondingly:

  • 357o - 180o = 177o
  • 310o - 180o = 130o

The MSA as an altitude is always expressed in feet.

Therefore, the MSA is:

  • 1 700 ft, clockwise between Radial 177 and Radial 130.
  • 2 300 ft, clockwise between Radial 130 and Radial 177°.
