Descent High 105-120

Question 1

1. (Refer to figure 177 and Legend 27.) What glide path and rate of descent should you plan to use initially to establish the glide slope for the ILS RWY 36L approach? (Use 120 knots ground speed.)

Answer 1

637 feet per minute

HI 120, half and half; 12, 6, 3, 7
(HIGH)

Question 2

2. (Refer to figure 188 and Legend 27.) For the LOC/DME RWY 21 at Portland International (PDX), what descent rate should the pilot expect at 120 knots ground speed?

Answer 2

720 fpm

HI 21 multiple from 7, 20 from 120
(HIGH)

Question 3

3. (Refer to figure 242.) What is the recommended descent angle and descent rate for the RNAV RWY 36 approach with a ground speed of 105 knots?

Answer 3

3.00* and 557 feet per minute

HI 5, from 105, 5, 5, 7
(HIGH)

Question 4

4. (Refer to figure 160 and Legend 27.) What is the approximate rate of descent. Required (for planning purposes) to maintain the electronic glide slope at 105 kts ground speed.

Answer 4

557 ft/min

HI 5, from 105, 5, 5, 7
(HIGH)
