SAAB 340 Limitations Memory Items FCOM Chapter 2 Flashcards
Wing span of SF340B & WT?
340B = 21.44m
340B(WT) = 22.75
When do Icing conditions exist?
Icing conditions exist when visible moisture in any form is present is present on the ramps, taxiways or runways and the OAT or SAT is +5°C and below during ground and flight operation. In these conditions, or whenever the blue ICE SPD status light or EAI is on, the minimum speed for flight in icing conditions must be observed. IAS
mode must be selected on the FD if climbing when these conditions exist.
What are examples of Visible Moisture?
clouds, fog with visibility of one mile (1,850 m) or less, rain, snow, sleet, ice crystals) or standing water, slush, or snow (hardpacked snow excluded)
Maximum Flaps Extended Speeds, VFE
7-15 degrees = 175 KIAS
20 degrees = 165 KIAS
35 degrees = 140 KIAS
When may flaps be extended and up to what altitude?
Flaps may be extended on the ground, as required for take-off, low altitude holding, approach and landing. Up to a maximum altitude of 14000 ft.

VLOEE
VLE
VLOR = 150 KIAS
VLOE = 200 KIAS
VLOEE = 200 KIAS
VLE = 200 KIAS
Minimum Control Speeds for SF340B & WT
VMCG
VMCA
VMCL Flaps 20 & 35
VMCG = Incorporated into calculations for RTOW charts
VMCA = Incorporated into calculations for RTOW charts
VMCL SF340B flaps 20 & 35 = 106 KIAS
VMCL SF340B(WT) Flaps 20 & 35 = 103 KIAS
Maximum Operating Speed VMO
VMO = 250 KIAS up to approx. 16,000 ft. Above this altitude VMO decreases as indicated by the VMO pointer to approx. 210 KIAS at 25,000 ft.
Maximum Manoeuvring Speed VA
180 KIAS
Maximum Rough Air Penetration Speed VRA
VRA = 190 KIAS up to 21,000 ft ISA. Above this altitude, reduce the speed as indicated by the VMO pointer minus 30 knots.
Maximum take-off Tailwind Component
10 Kts.
Maximum Landing Tailwind Component
10 kts.
Maximum Landing Tailwind Component for AFMS-54/55 (which aircraft are those allocated to)
15 kts. AFMS-54 is applicable to all 340(WT) aircraft.
AFMS-55 is applicable to ZPA, ZPB, ZPC, ZXF, ZXG, ZXK.
Airborne Collision Avoidance System (ACAS) deviations?
Deviations from the ATC assigned altitude is authorised only to the extent necessary to comply with an ACAS Resolution Advisory (RA).
Manoeuvres must not be based solely on information presented on the Traffic Advisory (TA).
Flight Director use
Use of flight director information in Go-around MODE (double click on Power Levers) during take-off is not authorised.
Auto pilot
Autopilot operations not authorised
- Below 200 ft AGL - During take-off or go-around.
- Below 500 ft AGL - During Cruise
- Below 50 ft AGL - During Approach
- Below 100 ft AGL - For non-coupled approach.
In Icing Conditions FD/AP IAS mode is the only vertical mode to be used during CLIMB when ice accumulation is observed or if it is not certain there is no ice accumulation on the aircraft.
It is a requirement to disconnect the autopilot following an engine failure and re-trim the aircraft before re-engagement of the autopilot.
Yaw Damper is not authorised when?
Take-off
Go-around
Landing
Landing Flap and flap in icing conditions
(when must landing flap be set by and called by?) Holding in icning conditions what flap setting must be used?
Landing flap is to be set by 300 ft radio height during normal landing. Company requires that the final flap setting is called for no less than 500 ft AGL.
When holding in icing conditions Flap 0 must be set.
Instrument colour codes
Operating limits = red
Caution, temporary or idle range = yellow
Normal operating range = green
Cargo fire protection length
35 min for B models
60 min for WT models
Attitude/Heading Reference System:
1. Can you move the aircraft during initialisation on the ground?
2. When is take off permitted after initialisation?
3. What is the attitude difference between both EADI’s and standby AI?
4. What is the compass checked for?
During initialisation on the ground the aircraft must not be moved.
Take-off is not permitted until two minutes after initialisation is completed and the attitude difference between the attitude displayed on both EADI’s and the standby attitude indicator is 3 degrees or less (BANK & PITCH) and the heading on the compass card is not slewing away from the aircraft heading.
