7.4 Approaches

Question 1

Maneuvering Speeds.

Answer 1

Minimum maneuvering speeds are calculated by adding 10 knots to the applicable flap setting speed, as indicated in the speed
book. This 10 knot additive provides adequate speed margin to stick shaker actuation for an inadvertent 15-degree overshoot
beyond the normal autopilot banked turn.

Question 2

Aircraft Approach Category.

Answer 2

For determining straight-in approach minimums the CRJ-200 and CRJ-900 are category D aircraft, and the CRJ-701 is a
category C aircraft.

Question 3

Approach Speed Additive (Gust Factor)

Answer 3

A final approach speed additive will only be applied for wind gusts.
To calculate, add ½ of the gust factor to VREF using a maximum of 10 knots to be flown for the approach.
EXAMPLE: Wind 280° at 15 gusting 23 knots.
Gust Factor is 8 knots (23-15 = 8).
½ of Gust Factor is 4 knots.
Bug should be set to VREF + 4 knots

Question 4

Approach Facility Identification.

Answer 4

If the approach navaid to be used does NOT have DME, the PM must audibly verify the navaid Morse code identification prior
to approach. If the approach navaid to be used DOES have DME, pilots may visually confirm the navaid identification on their
respective PFD prior to approach

Question 5

Approach Minimum References.

Answer 5

All Category I DA/MDA approach minimum references on the PFDs will be done using MDA set via the Air Data Reference
Panel (ARP). All nonprecision approaches will be flown to an “adjusted” MDA, which is the charted MDA rounded up to the
nearest 100’ (i.e. a published MDA of 610’ is set to 700’ and flown to 700’ minimums).
All Category II approach minimum references on the PFD’s will be done using DH (if available), set via the Air Data
Reference Panel (ARP). (i.e. An approach is published with a RA of 106’, set 106 for the DH.) When “RA NOT AUTH” is
specified on the approach chart use the Inner Marker or the barometric altitude DA(H) (Set the DA via the ARP), whichever
comes first, as the means for minima determination.

Question 6

Threshold Height

Answer 6

Height over the threshold is a function of glide path angle and glide path intercept point. During a typical 3-degree approach
with a 1,000 ft. touchdown point, the main landing gear will cross the threshold at approximately 50 feet.
Special attention must be given to establishing a final approach that will assure safe threshold clearance and touchdown 1,000
ft. down the runway and within the touchdown zone. Deviation from the visual glide path is not permitted in an attempt to
touch down shorter than normal. A go-around should be executed if threshold clearance is doubtful.

Question 7

Missed Approach

Answer 7

A missed approach is executed for many reasons including: unstable, runway environment not in sight, loss of runway
environment, etc.
Either the pilot flying or the pilot monitoring may make a go-around callout. The pilot flying will immediately execute a
missed approach.
