An aircraft is at FL120, flying heading 180 (south) toward a mountainous area. The highest terrain ahead is 9,500 ft. The aircraft has minimum obstacle clearance requirement of 1,000 ft. The minimum safe altitude for this aircraft on heading 180 in this area is:
Answer: 10,500 ft (FL105 approximately) — terrain 9,500 ft + 1,000 ft required clearance
Minimum safe altitude = highest terrain + required obstacle clearance = 9,500 + 1,000 = 10,500 ft.
Imagine a 3D radar display showing an aircraft at coordinates East 3, North 5, Altitude 8 (in arbitrary units). The aircraft moves: +2 East, -1 North, +2 Altitude. What are its new coordinates?
Answer: East 5, North 4, Altitude 10
East: 3+2=5. North: 5+(-1)=4. Altitude: 8+2=10. New position: East 5, North 4, Altitude 10.
On a plan view (top-down) radar display, an aircraft appears to be moving from lower-right to upper-left. On a north-up display, this corresponds to a heading of approximately:
Answer: 315 degrees (northwest) — lower-right to upper-left on a north-up display is northwest
On a north-up radar, lower-right = southeast, upper-left = northwest. Movement from southeast toward northwest = heading 315 (northwest).
An aircraft is in a 30-degree banked turn. Compared to a level coordinated flight, the vertical component of lift in this turn is:
Answer: Reduced — in a banked turn, lift is tilted sideways, reducing its vertical component
In a banked turn, the lift vector tilts with the bank angle. The vertical component decreases (cos 30° = 0.866), while horizontal lift provides centripetal force.
A holding pattern entry for an aircraft arriving from the southwest (heading 045, inbound to the hold fix) with right-hand turns is most correctly described as a:
Answer: Parallel entry — the aircraft first flies outbound parallel to the holding course
An aircraft arriving from the southwest heading 045 needs a parallel entry for a right-hand hold with inbound 090, as it arrives from the non-holding side requiring the parallel entry procedure.
Looking at a vertical profile of airspace, an aircraft is at FL230. Below it is Class C airspace from FL100 to FL195, and below that is Class D airspace from the surface to 3,000 ft. Class E airspace fills the gaps. The aircraft at FL230 is currently in:
Answer: Class E airspace — FL195 to the base of Class A airspace (FL550) contains Class E in this scenario
Class C ends at FL195 and Class A (in ICAO countries) starts at FL550 or higher. The gap FL195–FL550 is Class E airspace. FL230 falls within this Class E block.
