| Message | (Thursday 2005) Tomorrow we have the first test in Hawk AOI's and tomorrow week we'll have the final AOI test. I'm starting to get the hang of things but it's still rather challenging to shift gear when you've been at idle for so long, doing very little every day and then suddenly have to learn everything there is to know about an aircraft in nine days. The Hawk is so much different than the Harvard. I used to think that the T6 was complicated but compared to this it was pretty straight forward. For instance, the airframe "don't exceed" speed limit was 316kt or Mach 0.57 on the T6, whichever occurs first. On the Hawk, the same limit is 575kt at low altitude. Then as you climb higher, if you fly at 575kt, your Mach number will rise until you reach M0.9 which becomes your new speed limit. As you climb further and maintain M0.9, your indicated airspeed will fall and when you reach 500kt, maintaining M0.9, the 500kt becomes your new speed limit, until, at higher alititude, the new limiter becomes Mach 1.2 which is then kept until the aircraft service ceiling of 48,000 feet. That's just the airframe speed limt, then there are a bunch of G-limits, engine temperature & RPM limits etc. Not to mention that flaps at different settings and the landing gear have their own speed and g limits. And the crosswind component limits obviously vary depengin on whether you're flying a "clean" aircraft or if you have external tanks or weapons, if you use the drag chute on landing and if you're flying single or in formation. If you think the ejection seat is just a handle that you pull; well, think again! You'd be surprised as to how much relevant (from a pilot's prespective) information there is to know. And those are just the limitations. Then of course, the normal and emergency operating procedures, performance charts and just knowing how to use all the functions in the cockpit is a big job. The more you learn, the more you realise how little you know. It's a humbling experience to work on something so complex. I better stick my head back in the books. /GEA |
