14 ght Hours VS Maintenance Hours RW 1.5 hours of flight = 1 hour of maintenance 1 hour of flight = 3 hours of maintenance o, after a patient transfer that required three ight hours, a fixed wing aircraft requires 2 ours of maintenance, while a rotor wing ircraft requires 9 hours of maintenance

15 ght Hours VS Maintenance Hours, to provide 24/7 coverage for aircraft that are ntinually tasked, you need: fixed wing aircraft rotor wing aircraft

16 st

17 eed Max Speed 531 km/hr RW Max Speed 287 km/hr (max take off weight at sea level in standard atmospheric conditions

18 nge FW 3338 kms RW 761 kms (at long range cruise speed at 4000 ft altitude)

19 ng Air B200 Range

20 orsky 76 Helicopter Range

21 essurization Max Altitude 35,000 ft max altitude Pressure differential 6.6 psi Sea level cabin to 15,293 feet RW Max Altitude 13,800 ft max altitude

22 essurization

23 fect on the Patient Max Altitude At 10,000 feet altitude, a 50 ml pneumothorax would still have a volume of 50 mls in a pressurized cabin At 10,000 feet altitude, a 250 ml pneumothorax would still have a volume of 250 mls in a pressurized cabin RW Max Altitude At 10,000 feet a 50 ml pneumothorax will have expanded to 73 mls At 10,000 feet a 250 ml pneumothorax will have expanded to 363 mls

24 fect on the Patient

25 eather vcanada website: New Brunswick and the Gaspe eninsula have thunderstorm ctivity occurring, on average, etween 10 to 20 days a year hile Nova Scotia and Prince dward Island receive only bout half this number, or less

26 Able to fly in bad weather FW ft max RW 13, 800 ft max

27 erating Costs (including fuel) RW $2.60 USD per nm ($3.20 CAD per nm) $7.37 USD per nm ($9.06 CAD per nm)

28 ene Landings

29 ene Landings airly rare xcluded after dark (go to landing zones) enefit of scene landing is for sites that are within imited range of a Level 1 facility, otherwise the benefit s lost due to slower flight speed and the potential need o refuel estricted in bad weather fter 1100 there is a 1 hour response time

30 auma Patients Flown by ANB Air Ambulance

31 auma Patients Flown by ANB Air Ambulance patients 83 Adult, 18 Pediatric 7 were outside the range of the only available elicopter based in Halifax pproximately 50% of these occurred after dark

32 mmary ed Wing asier to fly ess mechanically complex n full engine failure has bility to glide ore reliable uieter (50 70 dba) ess expensive reater range Rotor Wing Hard to fly Mechanically complex Glides like a rock, but can autorotate Less reliable Higher noise levels (89 96 dba) More expensive Shorter range

33 mmary (cont.) ed Wing Faster almost twice the speed of rotor Altitude limit ft Can fly above or around bad weather Pressurized aircraft Reliable at night Many airports available for landing sites Rotor Wing Almost half the speed of fixed wing Altitude limit ft Unable to fly above or around bad weather Non pressurized aircraft Not typically utilized at night One approved Helipad next to Saint John Regional Hospital
