When do you need an alternate airport?
123 Rule one hour before, to one after your ETA, 2000 feet agl, or, 1500 above the HAT, whichever is higher, and 3 miles visibility, or 2 miles above the straight in minimums, whichever is greater
How do you identify the FAF?
Outer marker or glide slope intercept
What happens to TAS and IAS in a constant mach climb?
Climbing at a fixed Mach number will cause TAS and IAS values to decrease
What are the types of icing?
Clear Mixed Rime only
Holding speed limitations?
Below 6000ft MSL= 200 KIAS
6,001ft-14,000ft MSL= 230 KIAS
14,001ft MSL and up= 265 KIAS
What alternate weather is good enough to be an alternate?
Precision approach 600 ft 2sm
Non Precision approach 800 ft 2sm No instrument approaches must be able to descend from the MEA to airport in VFR
What is the holding speed at 10,000 ft?
230KIAS
What is VDP and where is it on the plate? How can you figure one when not on the plate If published, can you descend below it if visual, is it regulatory
Marked by a “V,” the VDP is the last point at which a descent from the MDA to to the touchdown zone can be made at a stable three degree glideslope.
What the MSA and what does it provide you?
The Minimum Sector Altitude (MSA) is the lowest altitude which may be used which will provide a minimum clearance of 300 m (1 000 ft) above all objects located in the area contained within a sector of a circle of 46 km (25 NM) radius centered on a radio aid to navigation.
What is the DH
Decision Height. The altitude AGL at which a decision must be made to continue on an ILS or execute the missed approach.
When you can descend below DH?
- You are in a continuous position to land using normal descent rate
- You have the required flight visibility
- You have the runway environment in sight
What is the difference between a swept wing and a straight wing?
Swept wing: Higher critical mach number, designed for high speed flight with poor slow flight characteristics. Stalls at the wingtips first. Straight wing: Better at slower speeds. Stalls at the wing root first.
How do you identify MAP if DME fails?
Timing
What are slats and what do they do?
slats are leading edge devices, helps with high stall speed associated with a swept wing aircraft. energizes the boundary layer and changes the camber of the wing to Lower stall speed
What is mach tuck?
Mach tuck is the nose-down pitching movement an aircraft experiences as it passes its critical Mach number (Mcrt
Swept wing advantages
Wing sweep allows a faster airfoil speed before critical mach is reached when compared to a straight wing.
How are Critical Mach, stall speed and altitude related?
As you climb in altitude your stall speed is increasing , your critical mach and stall speed will eventually converge (creating coffins corner)
What is the ILS critical hold short line?
ATC may direct aircraft and vehicles to remain outside of the ILS critical areas when weather is below 800’ ceiling AND/OR visibility is below 2SM and an aircraft is on the approach past the Outer Marker
What is viscous hydroplaning?
Hydroplaning that requires a very smooth surface (ie new pavement, rubber coated pavement). Thin layer of water, low tire speed. Anything more than gentle braking can cause tires to lock
What is maximum speed in class charlie airspace within 4 nm from an airport?
200 Knots
A crew-member must breathe oxygen above how many feet?
Above FL350 when one crew member leaves his station. Above FL410:one crew member wears mask at all times.
What is mach tuck?
Mach tuck is the nose-down pitching movement an aircraft experiences as it passes its critical Mach number (Mcrt).
What is the most dangerous type of precipitation?
Supercooled Water Droplets
What is the airway width communication range guaranteed by MOCA?
MINIMUM OBSTRUCTION CLEARANCE ALTITUDE (MOCA)- The lowest published altitude in effect between radio fixes on VOR airways, off-airway routes, or route segments which meets obstacle clearance requirements for the entire route segment and which assures acceptable navigational signal coverage only within 25 statute (22 nautical) miles of a VOR.
